Org mode for Emacs – Release notes

Org mode is for keeping notes, maintaining TODO lists, planning projects, and authoring documents with a fast and effective plain-text system.

Version 8.3

Incompatible changes

Properties drawers syntax changes

Properties drawers are now required to be located right after a headline and its planning line, when applicable.

It will break some documents as TODO states changes were sometimes logged before the property drawer.

The following function will repair them:

(defun org-repair-property-drawers ()
"Fix properties drawers in current buffer.
Ignore non Org buffers."
(when (eq major-mode 'org-mode)
(org-with-wide-buffer
(goto-char (point-min))
(let ((case-fold-search t)
"END[ \t]*\$"))))
(org-map-entries
(lambda ()
(unless (and inline-re (org-looking-at-p inline-re))
(save-excursion
(forward-line)
(when (org-looking-at-p org-planning-line-re) (forward-line))
(when (and (< (point) end)
(not (org-looking-at-p org-property-drawer-re))
(save-excursion
(and (re-search-forward org-property-drawer-re end t)
(eq (org-element-type
(save-match-data (org-element-at-point)))
'drawer))))
(insert (delete-and-extract-region
(match-beginning 0)
(min (1+ (match-end 0)) end)))
(unless (bolp) (insert "\n"))))))))))))


#+CATEGORY keywords no longer apply partially to document

It was possible to use several such keywords and have them apply to the text below until the next one, but strongly deprecated since Org 5.14 (2008).

#+CATEGORY keywords are now global to the document. You can use node properties to set category for a subtree, e.g.,

* Headline
:PROPERTIES:
:CATEGORY: some category
:END:


New variable to control visibility when revealing a location

org-show-following-heading, org-show-siblings, org-show-entry-below and org-show-hierarchy-above no longer exist. Instead, visibility is controlled through a single variable: org-show-context-detail, which see.

Replace disputed keys again when reading a date

org-replace-disputed-keys has been ignored when reading date since version 8.1, but the former behavior is restored again.

Keybinding for reading date can be customized with a new variable org-read-date-minibuffer-local-map.

No default title is provided when TITLE keyword is missing

Skipping TITLE keyword no longer provides the current file name, or buffer name, as the title. Instead, simply ignore the title.

Functions signature changes

• org-export-collect-footnote-definitions
• org-html-format-headline-function
• org-html-format-inlinetask-function
• org-latex-format-headline-function
• org-latex-format-inlinetask-function
• org-link-search

Default bindings of C-c C-n and C-c C-p changed

The key sequences C-c C-n and C-c C-p are now bound to org-next-visible-heading and org-next-visible-heading respectively, rather than the outline-mode versions of these functions. The Org version of these functions skips over inline tasks (and even-level headlines when org-odd-levels-only is set).

org-element-context no longer return objects in keywords

org-element-context used to return objects on some keywords, i.e., TITLE, DATE and AUTHOR. It now returns only the keyword.

Behavior of org-return changed

If point is before or after the headline title, insert a new line without changing the headline.

org-timer-default-timer type changed from number to string

If you have, in your configuration, something like (setq org-timer-default-timer 10) replace it with (setq org-timer-default-timer "10").

New features

Hierarchies of tags

The functionality of nesting tags in hierarchies is added to org-mode. This is the generalization of what was previously called "Tag groups" in the manual. That term is now changed to "Tag hierarchy".

The following in-buffer definition:

#+TAGS: [ Group : SubOne SubTwo ]
#+TAGS: [ SubOne : SubOne1 SubOne2 ]
#+TAGS: [ SubTwo : SubTwo1 SubTwo2 ]


Should be seen as the following tree of tags:

• Group
• SubOne
• SubOne1
• SubOne2
• SubTwo
• SubTwo1
• SubTwo2

Searching for "Group" should return all tags defined above. Filtering on SubOne filters also it's sub-tags. Etc.

There is no limit on the depth for the tag hierarchy.

Additional syntax is defined for grouptags if the tags in the group don't have to be distinct on a heading.

Grouptags had to previously be defined with { }. This syntax is already used for exclusive tags and Grouptags need their own, non-exclusive syntax. This behaviour is achieved with [ ]. Note: { } can still be used also for Grouptags but then only one of the given tags can be used on the headline at the same time. Example:

[ group : sub1 sub2 ]

* Test                                                            :sub1:sub2:


This is a more general case than the already existing syntax for grouptags; { }.

Define regular expression patterns as tags

Tags can be defined as grouptags with regular expressions as "sub-tags".

The regular expressions in the group must be marked up within { }. Example use:

#+TAGS: [ Project : {P@.+} ]


Searching for the tag Project will now list all tags also including regular expression matches for P@.+. Good for example if tags for a certain project is tagged with a common project-identifier, i.e. P@2014OrgTags.

Filtering in the agenda on grouptags (Tag hierarchies)

Filtering in the agenda on grouptags filter all of the related tags. Exception if filter is applied with a (double) prefix-argument.

Filtering in the agenda on subcategories does not filter the "above" levels anymore.

If a grouptag contains a regular expression the regular expression is also used as a filter.

Minor refactoring of org-agenda-filter-by-tag

Now uses the argument arg and optional argument exclude instead of strip and narrow. ARG because the argument has multiple purposes and makes more sense than strip now. The term narrowing is changed to exclude.

The main purpose is for the function to make more logical sense when filtering on tags now when tags can be structured in hierarchies.

Babel: support for sed scripts

Thanks to Bjarte Johansen for this feature.

Babel: support for Processing language

New ob-processing.el library.

This library implements necessary functions for implementing editing of Processing code blocks, viewing the resulting sketches in an external viewer, and HTML export of the sketches.

Check the documentation for more.

Thanks to Jarmo Hurri for this feature.

New behaviour for org-toggle-latex-fragment'

The new behaviour is the following:

• With a double prefix argument or with a single prefix argument when point is before the first headline, toggle overlays in the whole buffer;
• With a single prefix argument, toggle overlays in the current subtree;
• On latex code, toggle overlay at point;
• Otherwise, toggle overlays in the current section.

Additional markup with #+INCLUDE keyword

The content of the included file can now be optionally marked up, for instance as HTML. See the documentation for details.

File links with #+INCLUDE keyword

Objects can be extracted via #+INCLUDE using file links. It is possible to include only the contents of the object. See manual for more information.

Drawers do not need anymore to be referenced in #+DRAWERS

One can use a drawer without listing it in the #+DRAWERS keyword, which is now obsolete. As a consequence, this change also deprecates org-drawers variable.

org-edit-special can edit export blocks

Using C-c ' on an export block now opens a sub-editing buffer. Major mode in that buffer is determined by export backend name (e.g., "latex" → "latex-mode"). You can define exceptions to this rule by configuring org-src-lang-modes, which see.

Additional :hline processing to ob-shell

If the argument :hlines yes is present in a babel call, an optional argument :hlines-string can be used to define a string to use as a representation for the lisp symbol ='hline= in the shell program. The default is hline.

Markdown export supports switches in source blocks

For example, it is now possible to number lines using the -n switch in a source block.

New option in ASCII export

Plain lists can have an extra margin by setting org-ascii-list-margin variable to an appopriate integer.

New blocks in ASCII export

ASCII export now supports #+BEGIN_JUSTIFYRIGHT and #+BEGIN_JUSTIFYLEFT blocks. See documentation for details.

More back-end specific publishing options

The number of publishing options specific to each back-end has been increased. See manual for details.

Export inline source blocks

Inline source code was used to be removed upon exporting. They are now handled as standard code blocks, i.e., the source code can appear in the output, depending on the parameters.

Extend org-export-first-sibling-p and org-export-last-sibling-p

These functions now support any element or object, not only headlines.

New function: org-element-lineage

This function deprecates org-export-get-genealogy. It also provides more features. See docstring for details.

New filter: org-export-filter-body-functions

Functions in this filter are applied on the body of the exported document, befor wrapping it within the template.

Radio tables feature now relies on Org's export framework ("ox.el"). :no-escape parameter no longer exists, but additional global parameters are now supported: :raw, :backend. Moreover, there are new parameters specific to some pre-defined translators, e.g., :environment and :booktabs for orgtbl-to-latex. See translators docstrings (including orgtbl-to-generic) for details.

Non-floating minted listings in Latex export

It is not possible to specify #+attr_latex: :float nil in conjunction with source blocks exported by the minted package.

Field formulas can now create columns as needed

Previously, evaluating formulas that referenced out-of-bounds columns would throw an error. A new variable org-table-formula-create-columns was added to adjust this behavior. It is now possible to silently add new columns, to do so with a warning or to explicitly ask the user each time.

ASCII plot

Ability to plot values in a column through ASCII-art bars. See manual for details.

New hook: org-archive-hook

This hook is called after successfully archiving a subtree, with point on the original subtree, not yet deleted.

New option: org-attach-archive-delete

When non-nil, attachments from archived subtrees are removed.

New option: org-latex-caption-above

This variable generalizes org-latex-table-caption-above, which is now deprecated. In addition to tables, it applies to source blocks, special blocks and images. See docstring for more information.

New option: org-latex-prefer-user-labels

Headlines, for which the property UNNUMBERED is non-nil, are now exported without section numbers irrespective of their levels. The property is inherited by children.

Tables can be sorted with an arbitrary function

It is now possible to specify a function, both programatically, through a new optional argument, and interactively with f or F keys, to sort a table.

The TOC keywords now accepts an optional local parameter. See manual for details.

Countdown timers can now be paused

org-timer-pause-time now pauses and restarts both relative and countdown timers.

New option only-window for org-agenda-window-setup

When org-agenda-window-setup is set to only-window, the agenda is displayed as the sole window of the current frame.

{{{date}}} macro supports optional formatting argument

It is now possible to supply and optional formatting argument to {{{date}}}. See manual for details.

{{{property}}} macro supports optional search argument

It is now possible to supply an optional search option to {{{property}}} in order to retrieve remote properties optional. See manual for details.

New option org-export-with-title

It is possible to suppress the title insertion with #+OPTIONS: title:nil or globally using the variable org-export-with-title.

New entities family: " "

" " are used to insert up to 20 contiguous spaces in various back-ends. In particular, this family can be used to introduce leading spaces within table cells.

New MathJax configuration options

Org uses the MathJax CDN by default. See the manual and the docstring of org-html-mathjax-options for details.

New behaviour in org-export-options-alist'

When defining a back-end, it is now possible to specify to give parse' behaviour on a keyword. It is equivalent to call org-element-parse-secondary-string' on the value.

However, parsed KEYWORD is automatically associated to an :EXPORT_KEYWORD: property, which can be used to override the keyword value during a subtree export. Moreover, macros are expanded in such keywords and properties.

Viewport support in html export

Viewport for mobile-optimized website is now automatically inserted when exporting to html. See org-html-viewport for details.

New #+SUBTITLE export keyword

Org can typeset a subtitle in some export backends. See the manual for details.

Remotely edit a footnote definition

Calling org-edit-footnote-reference (C-c ') on a footnote reference allows to edit its definition, as long as it is not anonymous, in a dedicated buffer. It works even if buffer is currently narrowed.

New function org-delete-indentation bound to M-^

Work as delete-indentation unless at heading, in which case text is added to headline text.

Support for images in Texinfo export

Texinfo back-end now handles images. See manual for details.

Support for captions in Texinfo export

Tables and source blocks can now have captions. Additionally, lists of tables and lists of listings can be inserted in the document with #+TOC keyword.

Countdown timer support hh:mm:ss format

In addition to setting countdown timers in minutes, they can also be set using the hh:mm:ss format.

Extend org-clone-subtree-with-time-shift

org-clone-subtree-with-time-shift now accepts 0 as an argument for the number of clones, which removes the repeater from the original subtree and creates one shifted, repeating clone.

New time block for clock tables: untilnow

It encompasses all past closed clocks.

Support for the polyglossia LaTeX package

See the docstring of org-latex-classes and org-latex-guess-polyglossia-language for details.

Removed functions

Removed function org-translate-time

Use org-timestamp-translate instead.

Removed function org-beamer-insert-options-template

This function inserted a Beamer specific template at point or in current subtree. Use org-export-insert-default-template instead, as it provides more features and covers all export back-ends. It is also accessible from the export dispatcher.

Removed function org-timer-cancel-timer

org-timer-stop now stops both relative and countdown timers.

Removed function org-export-solidify-link-text

This function, being non-bijective, introduced bug in internal references. Use org-export-get-reference instead.

Removed function org-end-of-meta-data-and-drawers

The function is superseded by org-end-of-meta-data, called with an optional argument.

Removed functions org-table-colgroup-line-p, org-table-cookie-line-p

These functions were left-over from pre 8.0 era. They are not correct anymore. Since they are not needed, they have no replacement.

Removed options

org-list-empty-line-terminates-plain-lists is deprecated

It will be kept in code base until next release, for backward compatibility.

If you need to separate consecutive lists with blank lines, always use two of them, as if this option was nil (default value).

org-export-with-creator is a boolean

Special comment value is no longer allowed. It is possible to use a body filter to add comments about the creator at the end of the document instead.

Removed option org-babel-sh-command

This undocumented option defaulted to the value of shell-file-name at the time of loading ob-shell. The new behaviour is to use the value of shell-file-name directly when the shell langage is shell. To chose a different shell, either customize shell-file-name or bind this variable locally.

Removed option org-babel-sh-var-quote-fmt

This undocumented option was supposed to provide different quoting styles when changing the shell type. Changing the shell type can now be done directly from the source block and the quoting style has to be compatible across all shells, so a customization doesn't make sense anymore. The chosen hard coded quoting style conforms to POSIX.

Removed option org-insert-labeled-timestamps-at-point

Setting this option to anything else that the default value (nil) would create invalid planning info. This dangerous option is now removed.

Removed option org-entities-ascii-explanatory

This variable has no effect since Org 8.0.

Removed option org-table-error-on-row-ref-crossing-hline

This variable has no effect since August 2009.

Removed MathML-related options from org-html-mathjax-options

MathJax automatically chooses the best display technology based on the end-users browser. You may force initial usage of MathML via org-html-mathjax-template or by setting the path property of org-html-mathjax-options.

Removed comment-related filters

org-export-filter-comment-functions and org-export-filter-comment-block-functions variables do not exist anymore.

Miscellaneous

Strip all meta data from ITEM special property

ITEM special property does not contain TODO, priority or tags anymore.

File names in links accept are now compatible with URI syntax

Absolute file names can now start with /// in addition to /. E.g., [[file:///home/me/unicorn.jpg]].

Footnotes in included files are now local to the file

As a consequence, it is possible to include multiple Org files with footnotes in a master document without being concerned about footnote labels colliding.

Mailto links now use regular URI syntax

This change deprecates old Org syntax for mailto links: mailto:user@domain::Subject.

QUOTE keywords do not exist anymore

QUOTE keywords have been deprecated since Org 8.2.

Select tests to perform with the build system

The build system has been enhanced to allow test selection with a regular expression by defining BTEST_RE during the test invocation. This is especially useful during bisection to find just when a particular test failure was introduced.

Exact heading search for links now ignore spaces and cookies. This is the case for links of the form file:projects.org::*task title, as well as links of the form file:projects.org::some words when org-link-search-must-match-exact-headline is not nil.

org-latex-hyperref-template, org-latex-title-command formatting

New formatting keys are supported. See the respective docstrings. Note, org-latex-hyperref-template has a new default value.

float, wasysym, marvosym are removed from org-latex-default-packages-alist

If you require any of these package add them to your preamble via org-latex-packages-alist. Org also uses default LaTeX \tolerance` now.
