发布说明 | Org 主模式

This is for security reasons, to avoid running malicious commands.

python-mode.el support has been removed from ob-python.el. The related customization org-babel-python-mode has been changed to a constant.

If you still want to use python-mode with ob-python, you might consider ob-python-mode-mode, where the code to support python-mode has been ported to.

Org 9.6 introduced support for searching hidden parts of the links.

Unfortunately, we had to drop this support because its implementation turned out to be unreliable for many users. Proper implementation would require patching isearch.el and possibly a number of external libraries implementing isearch equivalents. It cannot be done on Org side alone.

org-latex-line-break-safe constant was previously introduced to deal with edge cases when LaTeX interprets […] as LaTeX command argument. However, it caused a number of other issues and proved itself not to be as "safe" as it supposed to be.

We now use a Pandoc's approach to deal with the same problem, utilizing {[} to escape [...] instances where needed.

Org mode now assumes tab width to be 8 characters, when calculating list and other indentation. tab-width is also set to 8 when Org major mode is loaded.

This is done to improve consistency of the markup for lists, where indentation affects list items.

Users with non-default values of tab-width should avoid overriding the value of 8 set by Org mode. If the custom tab-width value is smaller than 8, the existing Org documents can be converted to the new standard tab width using the following helper command:

(defun org-compat-adjust-tab-width-in-buffer (old-width)
  "Adjust visual indentation from `tab-width' equal OLD-WIDTH to 8."
  (interactive "nOld `tab-width': ")
  (cl-assert (derived-mode-p 'org-mode))
  (unless (= old-width 8)
    (org-with-wide-buffer
     (goto-char (point-min))
     (let (bound
           (repl (if (< old-width 8)
                     (make-string old-width ?\s)
                   (concat "\t" (make-string (- old-width 8) ?\s)))))
       (while (re-search-forward "^ *\t" nil t)
         (skip-chars-forward " \t")
         (setq bound (point-marker))
         (forward-line 0)
         (while (search-forward "\t" bound t)
           (replace-match repl)))))))

To follow Emacs coding conventions and to avoid confusion of users who accidentally get org-ctags autoloaded due to help completion, the library does not modify org-open-link-functions during loading any more. Run org-ctags-enable to setup hooks and advices:

(with-eval-after-load "org-ctags"
  (org-ctags-enable))

Previously, priority-up and priority-down in org-agenda-sorting-strategy used a composite rank depending on item's priority ([#A], [#B], [#C], etc) and overdue time to order agenda items (see "11.4.3 Sorting of agenda items" section of Org manual).

Now, this composite rank is renamed to urgency and the relevant sorting strategies are renamed to urgency-up and urgency-down. priority-up and priority-down sort by item's priority only.

Users relying on the previous composite ranking should adjust their agenda sorting settings.

In agenda views, org-priority-show command previously displayed the composite rank consisting of the item priority and overdue. This is no longer the case. The displayed and returned value only depends on the item priority now.

The behavior in Org buffers is unchanged.

iCalendar export now uses dos-style CRLF ("\r\n") line endings throughout, as required by the iCalendar specification (RFC 5545). Previously, the export used an inconsistent mix of dos and unix line endings.

This might cause errors in external packages that parse output from ox-icalendar. In particular, older versions of org-caldav may encounter issues, and users are advised to update to the most recent version of org-caldav. See this org-caldav commit for more information.

For TODOs without a scheduled start time, ox-icalendar no longer forces them to have a scheduled start time of today when exporting.

Instead, the new customization org-icalendar-todo-unscheduled-start controls the exported start date for unscheduled tasks. Its default is recurring-deadline-warning which will export unscheduled tasks with no start date, unless it has a recurring deadline (in which case the iCalendar spec demands a start date, and org-deadline-warning-days is used for that).

To revert to the old behavior, set org-icalendar-todo-unscheduled-start to current-datetime.

Previously, some link types where not exported as protocol:uri but as bare uri. This is now changed.

When a link is known by Org mode and does not have a custom :export parameter (see A.3 Adding Hyperlink Types section of the manual), the link protocol is now not stripped.

For example, if one adds a link type tel, but does not define :export parameter

(org-link-set-parameters "tel")

[[tel:12345][John Doe]] link will be correctly exported to LaTeX as \href{tel:12345}{John Doe}, not \href{12345}{John Doe}.

However, links like [[elisp:(+ 1 2)]] will be exported as \url{elisp:(+ 1 2)}, which may be somewhat unexpected.

Previously, link anchors for footnote references and footnote definitions were based on the footnote number: fn.1, fnr.15, etc.

Now, when the footnote has a non-number name, it is used as an anchor: fn.name, fnr.name.

Previously, when exporting to Org, all the citations and print_bibliography keywords, were transformed according to the chosen citation processor.

This is no longer the case. All the citation-related markup is now exported as is.

The previous behavior can be reverted by setting new custom option org-org-with-cite-processors.

ODT exporter used to open the exported file in archive-mode "for examination". This was not documented, was done in the background, and is not consistent with all other export backends. Now, this feature is removed.

Previously, when org-image-actual-width is a list or nil, Org used the first #+attr_... keyword containing :width ... to compute the inline image width. Now, #+attr_org, if present, takes precedence. In the following example the image preview has width of 75% while earlier versions pick 33%.

#+attr_html: :width 33%
#+attr_org:  :width 0.75
[[image.png]]

Previously, %i placeholders in the org-latex-to-mathml-convert-command and org-latex-to-html-convert-command user options were replaced with raw LaTeX fragment text, potentially triggering shell-expansion and incorrect result.

Now, the %i placeholders are shell-escaped to prevent shell expansion.

If you have single or double quotes around %i then update customizations and remove quotes.

Previously, calling org-insert-subheading on

* Heading 1
<point>* Heading 2

yielded

* Heading 1
** <point>
* Heading 2

This is no longer the case. The sub-heading is always created below current heading (prefix arguments have the same meaning as in org-insert-heading):

* Heading 1
* Heading 2
** <point>

Previously, file.org with the following contents

#+begin_src org :tangle file.org
Text
#+end_src

would overwrite itself.

Now, an error is thrown.

Org asks the user what must be done when pasting images and files copied to the clipboard from a file manager using the yank-media command. The default action can be set by customizing org-yank-dnd-method. The yank-media command was added in Emacs 29.

Images can be saved to a separate directory instead of being attached, customize org-yank-image-save-method.

Image filename chosen can be customized by setting org-yank-image-file-name-function which by default autogenerates a filename based on the current time.

Note that yank-media, as of Emacs 30, does not yet support Windows (Emacs bug#71909) and may not be always reliable on Mac (Emacs bug#71731).

By default, Org asks the user what to do with the dropped file like for pasted files. The same user option org-yank-dnd-method is respected.

Images dropped also respect the value of org-yank-image-save-method when org-yank-dnd-method is attach.

Adding search option by org-id-store-link can be disabled by setting org-id-link-use-context to nil, or toggled for a single call by passing universal argument.

When using this feature, IDs should not include ::, which is used in links to indicate the start of the search string. For backwards compatibility, existing IDs including :: will still be matched (but cannot be used together with search option). A new org-lint checker has been added to warn about this.

Previously, Org mode disallowed pop-up frames when displaying dispatch buffers. This is no longer the case. display-buffer-alist is fully obeyed.

org-switch-to-buffer-other-window and org-no-popups are now deprecated.

Running shell blocks with the :session header freezes Emacs until execution completes. The new :async header allows users to continue editing with Emacs while a :session block executes.

Repeating Scheduled and Deadline timestamps in TODOs are now exported as recurring tasks in iCalendar export.

In case the TODO has just a single planning timestamp (Scheduled or Deadline, but not both), its repeater is used as the iCalendar recurrence rule (RRULE).

If the TODO has both Scheduled and Deadline planning timestamps, then the following cases are implemented:

• If both have the same repeater, then it is used as the RRULE.
• Scheduled has repeater but Deadline does not: the Scheduled repeater is used as RRULE, and Deadline is used as UNTIL (the end date for the repeater). This is similar to repeated-after-deadline in org-agenda-skip-scheduled-if-deadline-is-shown.

The following 2 cases are not yet implemented, and the repeater is skipped (with a warning) if the ox-icalendar export encounters them:

• Deadline has a repeater but Scheduled does not.
• Scheduled and Deadline have different repeaters.

Also note that only vanilla repeaters are currently exported; the special repeaters ++ and .+ are skipped.

When FILE does not exist, the reference is searched in the current file, using the verbatim reference. This way, :var table=tbl:example will be searched inside the current buffer.

Previously, :extend t face attribute did not make folded headlines, blocks, and drawers extend their face beyond end of line.

Now, the ellipsis and trailing newline use the same face as the last character before the fold.

Previously, it was not possible to specify multi-line location, summary, or description when exporting to iCalendar.

In the following example, LOCATION was exported as "Someplace", ignoring the other lines.

* heading with multi-line property
:PROPERTIES:
:LOCATION: Someplace
:LOCATION+: Some Street 5
:LOCATION+: 12345 Small Town
:END:

Now, SUMMARY+, LOCATION+, and DESCRIPTION+ properties can be used to create multi-line values.

In the above example, LOCATION is now exported as

Someplace
Some Street 5
12345 Small Town

A new global export option :with-cite-processors, when set to nil, disables citation processors completely. This option is available to export backends via :options-alist when defining the backend.

The backends disabling citation processors must take care about exporting citation objects and print_bibliography keywords via transcoders.

Users can disable citations processors by customizing new org-export-process-citations option.

Org babel now uses session buffer (if it exists) to retrieve default-directory environment during src block evaluation.

By default, buffer named like session is checked. All the backends that create sessions inside buffers named differently should provide a function org-babel-session-buffer:<lang>. The function must accept two arguments - session name and info list (as returned by org-babel-get-src-block-info); and return the session buffer name.

With C-u prefix argument, force inserting a sibling heading below. With C-u C-u prefix argument, force inserting a child heading.

When region is active and starts at a heading, org-metaup and org-metadown will move all the selected subtrees.

Moving, promoting, and demoting of headings and items in region now do not deactivate Transient mark mode.

Users can thus conveniently select multiple headings/items and use, for example, M-<down>=/=M-<up> repeatedly without losing the selection.

A capture template can target (here) which is the equivalent of invoking a capture template with a zero prefix.

The colview dynamic block understands a new :formatter parameter, which specifies a user-supplied function to format and insert the data in the dynamic block.

A global default formatting function for colview dynamic blocks can be set via the new option org-columns-dblock-formatter which defaults to the new function org-columns-dblock-write-default, that implements the previous (fixed) formatting behavior. Hence, the default behavior is identical to previous versions.

The global default function can be overridden for any given colview dynamic block individually by specifying a custom formatter function using the new :formatter parameter on the block's BEGIN line.

This new feature replicates the :formatter option already available for clocktable dynamic blocks.

The colview dynamic block understands a new :link parameter, which when non-nil causes ITEM headlines in the table to be linked to their origins.

When org-babel-tangle-remove-file-before-write is set to t the tangle target is removed before writing. This will allow overwriting read-only tangle targets. However, when tangle target is a symlink, this will convert the tangle target into an ordinary file.

The default value is auto – overwrite tangle targets when they are read-only.

When called with a prefix argument, org-bibtex-yank adds data to the headline of the entry at point instead of creating a new one.

ob-plantuml.el now output tikz :file format via -tlatex:nopreamble option. So that the output tikz file can be an input into the exported latex correctly.

For example, exporting the following to LaTeX

will include the generated .tikz into the exported LaTeX source.

When org-num-skip-unnumbered is non-nil, org-num-mode now honors org-use-property-inheritance for UNNUMBERED property (see manual section "Property Inheritance"). Previously, only local UNNUMBERED property was taken into account.

Users can add "UNNUMBERED" to org-use-property-inheritance and set org-numb-skip-unnumbered to t to make org-num-mode skip numbering of all the sub-headings with non-nil UNNUMBERED property.

The prefix arguments are passed to org-insert-todo-heading.

sqlite source blocks with no :db header argument now make SQLite use a temporary in-memory database instead of throwing an error, matching the behavior of the official sqlite3 shell. As a result, sqlite source blocks are now usable out of the box, that is with no header arguments.

When org-return-follows-link is non-nil and cursor is over an org-cite citation, org-return will call org-open-at-point.

It supports inequality operators != and /= in addition to the less common (BASIC? Pascal? SQL?) <>. And it supports starred versions of all relational operators (<*, =*, !=*, etc.) that work like the regular, unstarred operators but match a headline only if the tested property is actually present.

ob-python now converts the following objects to org-mode tables when ":results table" header arg is set:

• Dictionaries
• Numpy arrays
• Pandas DataFrames
• Pandas Series

When the header argument :results graphics is set, ob-python will use matplotlib to save graphics. The behavior depends on whether value or output results are used. For value results, the last line should return a matplotlib Figure object to plot. For output results, the current figure (as returned by pyplot.gcf()) is cleared before evaluation, and then plotted afterwards.

ob-maxima has two new header arguments: :batch and :graphics-pkg.

The :batch header argument can be set to one of Maxima's file loaders (batch, load or batchload); the default remains batchload. The :graphics-pkg header argument can be set to one of Maxima's graphics packages (draw or plot); the default remains plot. The graphics terminal is now determined from the file-ending of the file-name set in the :file header argument.

ob-calc now supports tables in :var. They are converted to a matrix or a vector depending on the dimensionality of the table. A table with a single row is converted to a vector, the rest are converted to a matrix.

We use defaults based on the file name and title of the document, and place the entry in the Misc category if TEXINFO_DIR_CATEGORY is missing.

TEXINFO_DIR_TITLE is renamed to TEXINFO_DIR_NAME. The old name is obsolete.

Previously, fontification of inline source blocks, macros, footnotes, target links, timestamps, radio targets, targets, inline export snippets, verbatim code, and COMMENT keyword in headings replaced the containing element fontification. Now, this is changed - the inner markup faces and the containing element faces are combined, with "inner" faces taking precedence; just as for all other markup.

Previously, leading indentation and trailing newline in table rows were not fontified using org-table face. default face was used instead. This made it impossible to scale line height when org-table face has smaller height than default (Emacs calculates line height using the tallest face).

Now, new org-table-row face is used on the whole table row lines, including indentation and the final newline. This face, by default, inherits from org-table face.

If the new behavior is not desired, org-table-row face can be changed to inherit from default face. See "Customizing Faces" section of Emacs manual or "Face Attribute Functions" section of Elisp manual.

org-table takes precedence over org-table-row for the parts of table rows without indentation and newline.

Previously, only a subset of Org editing commands respected org-auto-align-tags option. Now, it is no longer the case. All the editing commands, including typing (org-self-insert-command) and deletion respect the option.

org-auto-align-tags is still enabled by default. For users who customized org-auto-align-tags to nil, org-edit-headline, org-priority, org-set-tags, org-entry-put, org-kill-line, and typing/deleting in headlines will no longer unconditionally auto-align the tags.

The new option makes Org expand environment variables in link and INCLUDE paths. The option is on by default.

Users who do not want variable expansion can set org-export-expand-links variable to nil or provide expand-links:nil in-file export option.

This new hook runs when a note has been stored.

Sorting of agenda items, tables, menus, headlines, etc can now be controlled using a new custom option org-sort-function.

By default, Org mode sorts things according to the operating system language. However, language sorting rules may or may not produce good results depending on the use case. For example, multi-language documents may be sorted weirdly when sorting rules for system language are applied on the text written using different language. Also, some operations systems (e.g. MacOS), do not provide accurate string sorting rules.

Org mode provides 3 possible values for org-sort-function:

1. (default) Sort using system language rules.
2. Sort using string comparison (compare-strings), making use of UTF case conversion. This may work better for mixed-language documents and on MacOS.
3. Custom function, if the above does not fit the needs.

Previously, ob-latex used org-preview-latex-default-process from org-preview-latex-process-alist to produce png output. Now, the process settings are separated into a new dedicated option org-babel-latex-process-alist.

The default value is pulled from dvipng process type from org-preview-latex-process-alist, preserving the existing behavior. However, the output is now immune to changes in org-preview-latex-default-process and can be customized independently of the image preview settings.

The string that separates the values of multi-valued results returned from Lua code blocks.

In ox-html, .avif image links are now inlined by default.

The new option defines name of an alternative environment to be used for fragile beamer frames. This option is needed to work around beamer bug with frame contents containing literal \end{frame} string (for example, inside example blocks). See https://github.com/josephwright/beamer/issues/360

The default value is orgframe.

The option should normally not be changed, except when you need to put \end{orgframe} string inside beamer frames.

A checker has been added to M-x org-lint to detect instances of org-beamer-frame-environment in Org documents.

The new option controls whether to use citation processors to process citations.

The new option controls whether to use citation processors to process citations when exporting to Org.

The new options controls whether to export special table rows in Org-Org (ox-org) export. The default value is t.

Org babel is often using Emacs's interactive REPL feature to implement :session functionality in code blocks. However, Emacs's REPLs use heuristics to detect which lines in the REPL buffer correspond to output and which lines are user prompts.

Normally, Org babel changes the default prompt to something unique. It avoids incorrect detection of code block output.

Sometimes, the Org-configured prompt is changed manually by users or when running a sub-REPL (for example, when running ssh/python interpreter inside shell).

The new option controls Org mode's heuristics for catching user-changed prompt in interactive Org babel sessions. When Org mode cannot find REPL's prompt for more than org-babel-comint-fallback-regexp-threshold seconds, imprecise generic prompt is tried to detect whether the code block output has arrived.

Users who often work with altering REPL prompts may consider reducing the default 5 second value of the new option.

A new custom option org-agenda-skip-scheduled-repeats-after-deadline is introduced in place of repeated-after-deadline value of org-agenda-skip-scheduled-if-deadline-is-shown.

The following example would no longer show in the agenda as scheduled after January 5th with the new customization set to t.

* TODO Do me every day until Jan, 5th (inclusive)
SCHEDULED: <2024-01-03 Wed +1d> DEADLINE: <2024-01-05 Fri>

The old customization will continue to work, ensuring backwards compatibility.

The option org-icalendar-ttl allows to advise a subscriber to the exported .ics file to reload after the given time interval.

This is useful i.e. if a calendar server subscribes to your exported file and that file is updated regularly.

See IETF RFC 5545, Section 3.3.6 Duration and https://en.wikipedia.org/wiki/ICalendar#Other_component_types for details.

Default for org-icalendar-ttl is nil. In that case the setting will not be used in the exported ICS file.

The option may also be set using the ICAL-TTL keyword.

Now, after attaching a file, [[attach:...]] link to the attached file is stored. It can later be inserted using M-x org-insert-link.

In addition to org-link-descriptive custom option, link display can now be controlled per-buffer as:

#+STARTUP: literallinks
#+STARTUP: descriptivelinks

You can now limit the total number of tags displayed in the fast tag selection interface. Useful in buffers with huge number of tags.

The variable is intended to be used by org-clock-out-hook. It is a flag used to signal when the CLOCK line has been removed. This can happen when org-clock-out-remove-zero-time-clocks is customized to be non-nil.

Users can now extend the value of org-info-other-documents to specify Urls to third-party (non-Emacs) online info nodes when exporting info: links.

Previously, smart quotes rules for different languages where hard-coded. Now, they can be customized by users.

New user option org-fold-catch-invisible-edits-commands controls which commands trigger checking for invisible edits.

The full list of affected commands is:

• org-self-insert-command
• org-delete-backward-char
• org-delete-char
• org-meta-return
• org-return (not checked in earlier Org versions)

New custom variable org-image-max-width limits the maximum inline image width, but only when the inline image width is not explicitly set via org-image-actual-width, ORG-IMAGE-ACTUAL-WIDTH property, or #+ATTR* keyword.

By default, when org-image-actual-width is set to t, org-image-max-width takes effect. Its default value is set to fill-column, limiting the image previews to fill-column number of characters.

To fall back to previous defaults, where the inline image width is not constrained, set org-image-max-width to nil.

It is now possible to customize face of source blocks without language specifier.

#+begin_src
Source block with no language
#+end_src

For example, to set highlight face, use

(setq org-src-fontify-natively t)
(add-to-list 'org-src-block-faces '("" highlight))

natbib citation export processor now uses org-cite-natbib-export-bibliography (defaults to unsrtnat) as a fallback bibliography style if none is specified by user in #+cite_export: keyword.

Previously, export would fail without explicitly selected bibliography style.

The escape %l in org-beamer-environments-extra inserts the label obtained from org-beamer--get-label. This is added to the default environments theorem, definition, example, and exampleblock in org-beamer-environments-default.

When xprintidle executable is available at org-clock load time, it is used as the default value for org-clock-x11idle-program-name. The old x11idle default is used as the fallback.

xprintidle is available as system package in most Linux distributions, unlike ancient x11idle that is distributed via WORG.

The org-cite-csl-latex-label-separator and org-cite-csl-latex-label-width-per-char options allow the user to control the indentation of entries for labeled bibliography styles when the "csl" citation processor is used for LaTeX export. The indentation length is computed as the sum of org-cite-csl-latex-label-separator and the maximal label width, for example:

    indentation length
<------------------------->
max. label width  separator
<---------------><-------->
[Doe22]                    John Doe. A title...
[DoeSmithJones19]          John Doe, Jane Smith and...
[SmithDoe02]               Jane Smith and John Doe...

The maximal label width, in turn, is calculated as the product of org-cite-csl-latex-label-width-per-char and the maximal label length measured in characters.

The org-cite-csl-latex-preamble option makes it possible to customize the entire LaTeX fragment that the "csl" citation processor injects into the preamble.

The org-latex-listings-src-omit-language option allows omitting the language parameter in the exported lstlisting environment. This is necessary when the listings backend delegates listing generation to another package like fancyvrb using the following setup in the document header:

#+LATEX_HEADER: \RequirePackage{fancyvrb}
#+LATEX_HEADER: \DefineVerbatimEnvironment{verbatim}{Verbatim}{...whatever...}
#+LATEX_HEADER: \DefineVerbatimEnvironment{lstlisting}{Verbatim}{...whatever...}

The face org-agenda-calendar-daterange is used to show entries with a date range in the agenda. It inherits from the default face in order to remain backward-compatible.

Before, a ClojureScript source block used the same backend as Clojure, configured in org-babel-clojure-backend and relied on an undocumented :target parameter.

Now, there's org-babel-clojurescript-backend to determine the backend used for evaluation of ClojureScript.

ob-clojure now supports executing babel source blocks with the official Clojure CLI tools. The command can be customized with ob-clojure-cli-command.

New custom variables org-export-body-only, org-export-visible-only, and org-export-force-publishing allow the default settings of "Body only", "Visible only", and "Force publishing" in the org-export-dispatch UI to be customized, respectively.

org-icalendar-todo-unscheduled-start controls how ox-icalendar exports the starting datetime for unscheduled TODOs. Note this option only has an effect when org-icalendar-include-todo is non-nil.

By default, ox-icalendar will not export a start datetime for unscheduled TODOs, except in cases where the iCalendar spec demands a start (specifically, for recurring deadlines, in which case org-deadline-warning-days is used).

Currently implemented options are:

• recurring-deadline-warning: The default as described above.
• deadline-warning: Use org-deadline-warning-days to set the start time if the unscheduled task has a deadline (recurring or not).
• current-datetime: Revert to old behavior, using the current datetime as the start of unscheduled tasks.
• nil: Never add a start time for unscheduled tasks. For repeating tasks this technically violates the iCalendar spec, but some iCalendar programs support this usage.

The capture template expansion element %K creates links using org-store-link, which respects the values of org-id-link-to-use-id.

The default Python command used by interactive sessions has been changed to match python-shell-interpreter and python-shell-interpreter-args by default. The default Python command for nonsessions has not changed.

New options org-babel-python-command-nonsession and org-babel-python-command-session control the default Python command for nonsessions and sessions, respectively. By default, org-babel-python-command-session is auto, which means to use the configuration for python-shell-interpreter(-args) as default.

The old option org-babel-python-command has been changed to have default value of auto. When not auto, it overrides both org-babel-python-command-nonsession and org-babel-python-command-session. Therefore, users who had previously set org-babel-python-command will not experience any changes.

Likewise, users who had neither set org-babel-python-command nor python-shell-interpreter(-args) will not see any changes – python remains the default command.

The main change will be for users who did not configure org-babel-python-command, but did configure python-shell-interpreter, e.g. to use IPython. In this case, ob-python will now start interactive sessions in a more consistent manner with run-python.

This allows to run functions after org-indent initializes a buffer to enrich its properties.

This option starts the agenda to automatically include archives, propagating the value for this variable to org-agenda-archives-mode. For acceptable values and their meaning, see the value of that variable.

For id: links, when this option is enabled, org-store-link will look for ids from parent/ancestor headlines, if the current headline does not have an id.

Combined with the new ability for id: links to use search options ¹, this allows linking to specific headlines without requiring every headline to have an id property, as long as the headline is unique within a subtree that does have an id property.

For example, given this org file:

* Parent
:PROPERTIES:
:ID: abc
:END:
** Child 1
** Child 2

Storing a link with point at "Child 1" will produce a link <id:abc::*Child 1>, which precisely links to the "Child 1" headline even though it does not have its own ID. By giving files top-level id properties, links to headlines in the file can also be made more robust by using the file id instead of the file path.

This new option allows you to define the LaTeX command the Org mode footnotes are converted to (for example \sidenote{%s%s} instead of the default \footnote{%s%s}).

The option can be customized either by

1. setting the global variable in the org-export-latex customization group or
2. by setting the file local keyword LATEX_FOOTNOTE_COMMAND

When using biblatex to export bibliographies, you can use the format as specified in the biblatex package documentation as key=val,key=val,...

colview dynamic blocks now understand a new :formatter parameter to use a specific function for formatting and inserting the contents of the dynamic block. This new option can be used to set the global default formatting function that will be used for colview dynamic blocks that do not specify any :formatter parameter. Its default value (the new function org-columns-dblock-write-default) yields the previous (fixed) formatting behavior.

Setting org-md-headline-style to 'mixed will export headline levels one and two as Setext style headlines, and headline levels three through six will be exported as ATX style headlines.

When org-footnote-auto-label is set to 'anonymous, create anonymous footnotes automatically with org-footnote-new.

The same can be done via startup options:

#+STARTUP: fnanon

Final hooks are added to the following commands:

• org-metaleft-final-hook to org-metaleft (bound to M-<left>).
• org-metaright-final-hook to org-metaright (bound to M-<right>).
• org-metaup-final-hook to org-metaup (bound to M-<up>).
• org-metadown-final-hook to org-metadown (bound to M-<down>).
• org-shiftmetaleft-final-hook to org-shiftmetaleft (bound to M-S-<left>).
• org-shiftmetaright-final-hook to org-shiftmetaright (bound to M-S-<right>).
• org-shiftmetaup-final-hook to org-shiftmetaup (bound to M-S-<up>).
• org-shiftmetadown-final-hook to org-shiftmetadown (bound to M-S-<down>).

Previously, diary type timestamps could not specify time. Now, it is allowed to add a time or time range:

<%%(diary-float t 4 2) 22:00-23:00>
<%%(diary-float t 4 2) 10:30>

The parsed representation of such timestamps will have :hour-start, :minute-start, :hour-end, :minute-end, and :range-type properties set appropriately. In addition, a new :diary-sexp property will store the diary sexp value.

For example,

<%%(diary-float t 4 2) 22:00-23:00>

will have the following properties

:type: diary
:range-type: timerange
:raw-value: "<%%(diary-float t 4 2) 22:00-23:00>"
:year-start: nil
:month-start: nil
:day-start: nil
:hour-start: 22
:minute-start: 0
:year-end: nil
:month-end: nil
:day-end: nil
:hour-end: 23
:minute-end: 0
:diary-sexp: "(diary-float t 4 2)"

Previously, Org mode interpreted (_text_) as subscript. Now, the interpretation is changed to underline.

(_text_) matches both subscript and underline markup. The interpretation is changed to keep consistency with other emphasis like (*bold*).

Most of the users should not be affected by this change - it only applies when character immediately preceding _ is one of -, (, ', and {.

To reduce confusion with "element" referring to both "syntax element" and "element/object" class, we now prefer using "syntax node" when referring to generic Org syntax elements. "Elements" and "objects" now refer to different syntax node classes of paragraph-like nodes and markup-like nodes.

Secondary strings can now be recognized as anonymous type to distinguish from non-elements. With a new optional argument, org-element-type will return anonymous for secondary strings instead of nil.

The new element type can be used in org-element-lineage, org-element-map, and other functions that filter by element type.

The code relying upon the previously used (TYPE PROPERTIES-PLIST CONTENTS-LIST) structure may no longer work. Please use org-element-create, org-element-property, and other Org element API functions to work with Org syntax trees.

Some syntax node properties are no longer stored as property list elements. Instead, they are kept in a special vector value of a new :standard-properties property. This is done to improve performance.

If there is a need to traverse all the node properties, a new API function org-element-properties-map can be used.

Properties and their values can now be deferred to avoid overheads when parsing. They are calculated lazily, when the value/property is requested by org-element-property and other getter functions. Using plist-get to retrieve values of PROPERTIES-PLIST is not recommended as deferred properties will not be resolved in such scenario.

New special property :secondary is used internally to record which properties store secondary objects.

New special property :deferred is used to keep information how to calculate property names lazily.

See the commentary in lisp/org-element-ast.el for more details.

Previously,

#+caption: foo
#+caption: bar
Paragraph

would have its :caption property set to (("bar") ("foo")) in reverse order.

Now, the order is not reversed: (("foo") ("bar")).

org-element-at-point, org-element-context, and org-element-at-point-no-context may now not calculate all the property values at the call time. Instead, the calculation will be deferred until org-element-property or the equivalent getter function is called. The property names may not all be calculated as well.

It may often be necessary to have the original Org buffer open when resolving the deferred values.

One can ensure that all the deferred values are resolved using new function org-element-resolve-deferred and new optional argument for org-element-property.

org-element-parse-buffer and org-element-parse-secondary-string will resolve all the deferred values by default. No adjustment is needed for their users.

The following functions are updated:

• org-agenda-entry-get-agenda-timestamp
• org-element-at-point
• org-is-habit-p
• org-id-get
• org-with-point-at
• org-entry-properties
• org-entry-get
• org-entry-delete
• org-entry-add-to-multivalued-property
• org-entry-remove-from-multivalued-property
• org-entry-member-in-multivalued-property
• org-entry-put-multivalued-property
• org-entry-get-with-inheritance
• org-entry-put
• org-read-property-value
• org-property-get-allowed-values

The traverse order for dual keywords is reversed. The main value is now traversed first, followed by the secondary value.

Org parser now assigns a new property :buffer that holds non-printable buffer object. This makes syntax tree non-printable. Using print~/~read is no longer safe.

org-element-at-point, org-element-context, org-get-category, and org-get-tags may modify the match data.

The relevant function docstrings now explicitly mention that match data may be modified.

When CHILDREN is a single anonymous node, use its contents as children nodes. This way,

(org-element-create 'section nil (org-element-contents node))

will yield expected results with contents of another node adopted into a newly created one.

Previously, one had to use

(apply #'org-element-create 'section nil (org-element-contents node))

org-element-timestamp-parser now adds :range-type property to each timestamp object. Possible values: timerange, daterange, nil.

org-element-timestamp-interpreter takes into account this property and returns an appropriate timestamp string.

org-element-timestamp-parser now adds :repeater-deadline-value and :repeater-deadline-unit properties to each timestamp object that has a repeater deadline. For example, in <2012-03-29 Thu ++1y/2y>, 2y is the repeater deadline with a value of 2 and unit of y. See "5.3.3 Tracking your habits" section in the manual.

Possible values for :repeater-deadline-value: positive integer, nil.

Possible values for :repeater-deadline-unit: hour, day, week, month, year.

org-element-timestamp-interpreter takes into account these properties and returns an appropriate timestamp string.

The :store: functions set for link types using org-link-set-parameters are now passed an interactive? argument, indicating whether org-store-link was called interactively.

Existing store functions will continue to work.

The TEST parameter is better served by Emacs debugging tools.

The old name is marked obsolete and the new name is org--print-speed-command.

This function was always aimed for internal use when building speed command help buffer. Now, it is stated explicitly.

Previously, when org-link-file-path-type is set to a function, the function argument was the filename from the link expanded via expand-file-name. Now, a bare filename is passed to the function.

In Org <9.0, org-create-file-search-functions could set description variable to suggest link description for the stored link. However, this feature stopped working since Org 9.0 switched to lexical binding.

Now, it is again possible for org-create-file-search-functions to supply link descriptions using (org-list-store-props :description "suggested description") in the search function body.

Elisp programs can now store data inside Org element cache.

The data will remain stored as long as the Org buffer text associated with the cached elements remains unchanged.

Two options are available:

• Store the data until any text within element boundaries is changed
• Store the data, but ignore any changes inside element contents that do not affect the high-level element structure. For example, changes inside subheadings can be ignored for the data stored inside parent heading element.

The new functions are: org-element-cache-store-key and org-element-cache-get-key.

When the new argument is non-nil, add data to the headline of the entry at point.

org-fold-hide-drawer-all is now a command, accepting two optional arguments - region to act on.

When TYPES is symbol, only check syntax nodes of that type.

With the new argument, the contents is copied recursively.

The value of the new optional argument DFLT is returned if the property with given name is not present. Same as DEFAULT argument for alist-get.

New optional argument FORCE-UNDEFER modifies the NODE, storing the resolved deferred values.

See the top comment in lisp/org-element-ast.el for more details about the deferred values.

New optional argument NO-UNDEFER, when non-nil, will make org-element-map keep deferred secondary string values in their raw form. See the top comment in lisp/org-element-ast.el for more details about the deferred values.

TYPES argument can now be set to t. This will match all the syntax nodes when traversing the tree.

FUN can now be a lisp form that will be evaluated with symbol node assigned to the current syntax node.

FUN can now throw :org-element-skip signal to skip recursing into current element children and secondary strings.

When non-nil, the deferred values and properties will not be resolved. See the top comment in lisp/org-element-ast.el for more details about the deferred values.

When the new argument is non-nil, return symbol anonymous for anonymous elements. Previously, nil would be returned.

The old name is kept as an alias. The new name creates less confusion as the function can also act on objects.

The old name is kept as an alias. The new name creates less confusion as the function can also act on objects.

A numeric value forces a heading at that level to be inserted. For backwards compatibility, non-numeric non-nil values insert level 1 headings as before.

New optional argument INHERIT means inherited ID properties from parent entries are considered when getting an entry's ID (see org-id-link-consider-parent-id option).

If a missing heading is created to match the search string, the new optional argument NEW-HEADING-CONTAINER specifies where in the buffer it will be added. If not specified, new headings are created at level 1 at the end of the accessible part of the buffer, as before.

Completion is enabled for links to man pages added using org-insert-link: C-c C-l man RET emacscl TAB to get emacsclient. Of course, the ol-man library should be loaded first.

TODO state, priority, tags, statistics cookies, and COMMENT keywords are allowed in the tree structure.

You can now retrieve the destination of a link by calling (thing-at-point 'url). Requires Emacs 28 or newer.

In Emacs 30 or newer, forward-thing and bounds-of-thing-at-point is also supported for links.

When Emacs is built with dbus support and the org.freedesktop.login1 interface is available, fallback to checking the IdleSinceHint property when determining org-user-idle-seconds as the penultimate step.

When column format contains width specifications, colview dynamic block now writes these specifications as column width in the generated tables and automatically shrinks the columns on display.

Example:

* PROYECTO EMACS
:PROPERTIES:
:COLUMNS:  %10ITEM(PROJECT)
:END:

Before

#+BEGIN: columnview :id local
| PROJECT        |
|----------------|
| PROYECTO EMACS |
#+END:

After

#+BEGIN: columnview :id local
| <10>           |
| PROJECT        |
|----------------|
| PROYECTO EMACS |
#+END:

Lua code blocks can now return values of any type and can also return multiple values. Previously, values of certain types were incorrectly converted to the empty string "", which broke HTML export for inline code blocks, and multiple values were incorrectly concatenated, where return 1, 2, 3 was evaluated as 123.

Multiple values are comma-separated by default, so that they work well with inline code blocks. To change the string used as the separator, customize org-babel-lua-multiple-values-separator.

Previously, when the link to be stored were stored already, org-store-link displayed a message and did nothing.

Now, org-store-link moves the stored link to front of the list of stored links. This way, the link will show up first in the completion and when inserting all the stored links with org-insert-all-links.

When editing a Python src block, the editing buffer is now associated with the Python shell specified by the src block's :session header, which means users can now send code directly from the edit buffer, e.g., using C-c C-c, to the session specified in the Org buffer.

Previously, when R/Julia source block had :session header argument set to a session name with "earmuffs" (like *session-name*), org-edit-special always started a session, if it does not exist.

Now, org-edit-special arranges that a new session with correct name is initiated only when user explicitly executes R/Julia-mode commands that trigger session interactions (requires ESS 24.01.0 or newer). The same session will remain available in the context of Org babel.

Previously, when storing id: link, org-store-link stored an additional "human readable" link using a node's CUSTOM_ID property.

This behavior has been expanded to store an additional CUSTOM_ID link when storing any type of external link type in an Org file, not just id: links.

Currently, the STYLE property of habits is not inherited when searching for entries.

This change allows the property to be inherited optionally by customizing the org-use-property-inheritance variable.

This change aims to provide more flexibility in managing habits, allowing users to dedicate separate subtrees or files to habits without manually setting the STYLE property for each sub-task.

The change is breaking when org-use-property-inheritance is set to t.

Previously, all the header arguments where stripped from src blocks during export. Now, header arguments are preserved.

Previously, when exporting to Org, special table rows (for example, width cookies) were not exported. Now, they are exported by default.

You can customize new option org-org-with-special-rows to fall back to previous behavior.

Previously, org-agenda-search-headline-for-time made Org agenda match anything resembling time inside headings. Even when the time was a part of a timestamp.

Now, all the timestamps in headings are ignored when searching the time.

Previously, all the text was unfolded unconditionally, including property drawers.

When certain objects in Org document are to be excluded from export, spaces after these objects were previously removed as well.

For example, if org-export-with-footnotes is set to nil, the footnote in

Pellentesque dapibus suscipit ligula.[fn:1]  Donec posuere augue in quam.

would be removed, leading to the following exported ASCII document

Pellentesque dapibus suscipit ligula.Donec posuere augue in quam.

This is because spaces after footnote (and other markup) are considered a part of the preceding AST object in Org.

Now, unless there is a whitespace before an object to be removed, spaces are preserved during export:

Pellentesque dapibus suscipit ligula.  Donec posuere augue in quam.

The :target header was only used internally to distinguish from Clojure and ClojureScript. This is now handled with an optional function parameter in the respective functions that need this information.

For symmetry with \S and \sect for the section symbol, \P has been added as an another form for the pilcrow symbol currently available as \para.

It does no longer use regexps.

It is also faster. Large tables can be read quickly.
