## Version 9.4

### Incompatible changes

[[*Headline][A link to a headline]]


[[*TODO Headline][A link to a headline]]


Following the link above will result in an error: the TODO keyword should not be part of internal file links.

You can use the following command to fix links in an Org buffer:

(defun org-fix-links ()
Go through the buffer and ask for the replacement."
(interactive)
(visible-mode 1)
(save-excursion
(goto-char (point-min))
(let ((regexp (format "\\[\\[\\*%s\\s-+"
(regexp-opt org-todo-keywords-1 t))))
(while (re-search-forward regexp nil t)
(when (and (save-excursion
(goto-char (match-beginning 0))
(y-or-n-p "Fix link (remove TODO keyword)? "))
(replace-match "[[*")))))
(visible-mode -1))


#### Calling conventions changes when opening or exporting custom links

This changes affects export back-ends, and libraries providing new link types.

Function used in :follow link parameter is required to accept a second argument. Likewise, function used in :export parameter needs to accept a fourth argument. See org-link-set-parameters for details.

Eventually, the function org-export-custom-protocol-maybe is now called with a fourth argument. Even though the 3-arguments definition is still supported, at least for now, we encourage back-end developers to switch to the new signature.

#### Python session return values must be top-level expression statements

Python blocks with :session :results value header arguments now only return a value if the last line is a top-level expression statement. Also, when a None value is returned, "None" will be printed under "#+RESULTS:", as it already did with :results value for non-session blocks.

#### In HTML export, change on how outline-container-* is set

When the headline has a CUSTOM_ID, use this custom id to build the div id. For example, if you have :CUSTOM_ID: my-headline then the resulting <div> will be <div id="outline-container-my-headline">.

You may want to check whether your HTML files are rendered differently after this change.

#### New keybinding <C-c C-TAB> for org-force-cycle-archived

org-force-cycle-archived used to be associated with <C-TAB> but this keybinding is used in Emacs for navigating tabs in Emacs. The new keybinding is <C-c C-TAB>.

### New default settings for some options

These options now default to t:

• org-loop-over-headlines-in-active-region
• org-fontify-done-headline
• org-src-tab-acts-natively

You may want to read the docstrings of these options to understand the consequences of this change.

Also, org-startup-folded now defaults to showeverything.

### New features

#### Looping agenda commands over headlines

org-agenda-loop-over-headlines-in-active-region allows you to loop agenda commands over the active region.

When set to t (the default), loop over all headlines. When set to 'start-level, loop over headlines with the same level as the first headline in the region. When set to a string, loop over lines matching this regular expression.

#### New minor mode org-table-header-line-mode

Turn on the display of the first data row of the table at point in the window header line when this first row is not visible anymore in the buffer.

You can activate this minor mode by default by setting the option org-table-header-line-p to t. You can also change the face for the header line by customizing the org-table-header face.

#### New minor mode org-list-checkbox-radio-mode

When this minor mode is on, checkboxes behave as radio buttons: if a checkbox is turned on, other checkboxes at the same level are turned off.

If you want to occasionally toggle a checkbox as a radio button without turning this minor mode on, you can use <C-c C-x C-r> to call org-toggle-radio-button.

You can also add #+ATTR_ORG: :radio t right before the list to tell Org to use radio buttons for this list only.

#### New allowed value for org-adapt-indentation

org-adapt-indentation now accepts a new value, 'headline-data.

When set to this value, Org will only adapt indentation of headline data lines, such as planning/clock lines and property/logbook drawers. Also, with this setting, org-indent-mode will keep these data lines correctly aligned with the headline above.

#### Numeric priorities are now allowed (up to 65)

You can now set org-priority-highest/lowest/default to integers to use numeric priorities globally or set, for example

to define a buffer-local range and default for priorities. Priority commands should work as usual. You cannot use numbers superior to 64 for numeric priorities, as it would clash with priorities like [#A] where the "A" is internally converted to its numeric value of 65.

#### Property drawers allowed before first headline

Property drawers are now allowed before the first headline.

Org mode is moving more towards making things before the first headline behave just as if it was at outline level 0. Inheritance for properties will work also for this level. In other words: defining things in a property drawer before the first headline will make them "inheritable" for all headlines.

#### Refinement in window behavior on exiting Org source buffer

After editing a source block, Org will restore the window layout when org-src-window-setup is set to a value that modifies the layout.

#### Display remote inline images

Org now knows how to display remote images inline.

Whether the images are actually displayed is controlled by the new option org-display-remote-inline-images.

#### New option to resolve open clock at a provided time

org-resolve-clocks now has a t' option, which works just like the k' option, but the user specifies a time of day, not a number of minutes.

#### Allow text rescaling in column view

You can now use C-x C-+ in column view: the columns face size will increase or decrease, together with the column header size.

#### New startup option #+startup: num

When this startup option is set, display headings as numerated.

Use #+startup: nonum to turn this off.

#### New tool for custom links

Org provides a new tool org-link-open-as-file, useful when defining new link types similar to "file"-type links. See docstring for details.

#### New optional numeric argument for org-return

In situations where org-return calls newline, multiple newlines can now be inserted with this prefix argument.

#### New source code block header argument :file-mode

Source code block header argument :file-mode can set file permissions if :file argument is provided.

#### RET and C-j now obey electric-indent-mode

Since Emacs 24.4, electric-indent-mode is enabled by default. In most major modes, this causes RET to reindent the current line and indent the new line, and C-j to insert a newline without indenting.

Org mode now obeys this minor mode: when electric-indent-mode is enabled, and point is neither in a table nor on a timestamp or a link:

• RET (bound to org-return) reindents the current line and indents the new line;
• C-j (bound to the new command org-return-and-maybe-indent) merely inserts a newline.

To get the previous behaviour back, disable electric-indent-mode explicitly:

(add-hook 'org-mode-hook (lambda () (electric-indent-local-mode -1)))


#### ob-C.el allows the inclusion of non-system header files

In C and C++ blocks, :includes arguments that do not start with a < character will now be formatted as double-quoted #include statements.

#### ob-clojure.el supports inf-clojure.el and ClojureScript evaluation

You can now set (setq org-babel-clojure-backend 'inf-clojure) and evaluate Clojure source blocks using inf-clojure. With a header argument like :alias "alias" the Clojure REPL will boot with clojure -Aalias. Otherwise Clojure will boot with lein, boot or tools.deps, depending on whether the current directory contains a project.clj, build.boot or deps.edn, falling back on inf-clojure-generic-cmd in case no such file is present.

Also, when using cider, you can now use #+begin_src clojurescript to execute ClojureScript code from Org files. Note that this works only if your Org file is associated with a cider session that knows how to run ClojureScript code. A bare lein repl session outside of a directory configured for ClojureScript will not work.

#### ob-java.el supports Java command line arguments

Babel Java blocks recognize header argument :cmdargs and pass its value in call to java.

#### ob-screen.el now accepts :screenrc header argument

Screen blocks now recognize the :screenrc header argument and pass its value to the screen command via the "-c" option. The default remains /dev/null (i.e. a clean screen session)

#### ob-plantuml: now supports using PlantUML executable to generate diagrams

Set org-plantuml-exec-mode to 'plantuml in order to use the executable instead of JAR. When using an executable it is also possible to configure executable location as well as arguments via: org-plantuml-executable-path and org-plantuml-executable-args.

### New commands

#### org-table-header-line-mode

Turn on a minor mode to display the first data row of the table at point in the header-line when the beginning of the table is invisible.

#### org-agenda-ctrl-c-ctrl-c

Hitting <C-c C-c> in an agenda view now calls org-agenda-set-tags.

#### org-hide-entry

This command is the counterpart of org-show-entry.

#### org-columns-toggle-or-columns-quit

<C-c C-c> bound to org-columns-toggle-or-columns-quit replaces the recent org-columns-set-tags-or-toggle. Tag setting is still possible via column view value edit or with <C-c C-q>.

#### org-datetree-find-month-create

Find or create a month entry for a date.

### New options and settings

#### New option org-html-prefer-user-labels

When non-nil, use NAME affiliated keyword, or raw target values, to generate anchor's ID. Otherwise, consistently use internal naming scheme.

CUSTOM_ID values are still always used, when available.

#### New option for using tabs in org-agenda-window-setup

Choosing other-tab for org-agenda-window-setup will open the agenda view in a new tab. This will work with versions of Emacs since 27.1 when tab-bar-mode was introduced.

#### New option org-table-header-line-p

Setting this option to t will activate org-table-header-line-mode in org-mode buffers.

#### New option org-startup-numerated

When this option is t, Org files will start using (org-num-mode 1) and headings will be visually numerated.

You can turn this on/off on a per-file basis with #+startup: num or #+startup: nonum.

#### New option org-clock-auto-clockout-timer

When this option is set to a number and the user configuration contains (org-clock-auto-clockout-insinuate), Org will clock out the currently clocked in task after that number of seconds of idle time.

This is useful when you often forget to clock out before being idle and don't want to have to manually set the clocking time to take into account.

#### New option to group captured datetime entries by month

A new :tree-type month' option was added to org-capture-templates to group new datetime entries by month.

#### New option to show source buffers using "plain" display-buffer

There is a new option plain to org-src-window-setup to show source buffers using display-buffer. This allows users to control how source buffers are displayed by modifying display-buffer-alist or display-buffer-base-action.

#### New option org-archive-subtree-save-file-p

Archiving a subtree used to always save the target archive buffer. Commit b186d1d7 changed this behavior by always not saving the target buffer, because batch archiving from agenda could take too much time.

This new option org-archive-subtree-save-file-p defaults to the value from-org so that archiving a subtree will save the target buffer when done from an org-mode buffer, but not from the agenda. You can also set this option to t or to from-agenda.

#### New option org-latex-to-html-convert-command

This new option allows you to convert a LaTeX fragment directly into HTML.

#### New option org-babel-shell-results-defaults-to-output

By default, source code blocks are executed in "functional mode": it means that the results of executing them are the value of their last statement (see the documentation.)

The value of a shell script's execution is its exit code. But most users expect the results of executing a shell script to be its output, not its exit code.

So we introduced this option, that you can set to nil if you want to stick using :results value as the implicit header.

In all Babel libraries, the absence of a :results header should produce the same result than setting :results value, unless there is an option to explicitly create an exception.

See this thread for more context.

#### New option in org-attach-store-link-p

org-attach-store-link-p has a new option to store a file link to the attachment.

#### New option org-fontify-todo-headline

This feature is the same as org-fontify-done-headline, but for TODO headlines instead. This allows you to distinguish TODO headlines from normal headlines. The face can be customized via org-headline-todo.

#### New default value for org-file-apps

The new value uses Emacs as the application for opening directory.

#### New hook org-agenda-filter-hook

Functions in this hook are run after org-agenda-filter is called.

### Removed or renamed functions and variables

#### Deprecated org-flag-drawer function

Use org-hide-drawer-toggle instead.

#### Deprecated org-hide-block-toggle-maybe function

Use org-hide-block-toggle instead.

#### Deprecated org-hide-block-toggle-all function

This function was not used in the code base, and has no clear use either. It has been marked for future removal. Please contact the mailing list if you use this function.

#### Deprecated org-return-indent function

In Elisp code, use (org-return t) instead. Interactively, C-j is now bound to org-return-and-maybe-indent, which indents the new line when electric-indent-mode is disabled.

#### Removed org-maybe-keyword-time-regexp

The variable was not used in the code base.

#### Removed org-export-special-keywords

The variable was not used in the code base.

#### Renamed org-at-property-block-p

The new name is org-at-property-drawer-p, which is less confusing.

#### Renamed priority options

From org-lowest-priority to org-priority-lowest. From org-default-priority to org-priority-default. From org-highest-priority to org-priority-highest. From org-enable-priority-commands to org-priority-enable-commands. From org-show-priority to org-priority-show.

### Miscellaneous

#### ob-screen.el now respects screen :session name

Screen babel session are now named based on the :session header argument (defaults to default).

Previously all session names had org-babel-session- prepended.

#### Forward/backward paragraph functions in line with the rest of Emacs

org-forward-paragraph and org-backward-paragraph, bound to <C-UP> and <C-DOWN> functions mimic more closely behaviour of forward-paragraph and backward-paragraph functions when available.

They also accept an optional argument for multiple calls.

See their docstring for details.

#### org-table-to-lisp no longer checks if point is at a table

The caller is now responsible for the check. It can use, e.g., org-at-table-p.

The function is also much more efficient than it used to be, even on very large tables.

#### Drawers' folding use an API similar to block's

Tooling for folding drawers interactively or programmatically is now on par with block folding. In particular, org-hide-drawer-toggle, a new function, is the central place for drawer folding.

#### Duration can be read and written in compact form

org-duration-to-minutes understands 1d3h5min as a duration, whereas org-duration-from-minutes can output this compact form if the duration format contains the symbol compact.

#### C-n, C-p, SPC and DEL in agenda commands dispatch window

You can now use <C-n>, <C-p>, <SPC> and <DEL> key to scroll up and down the agenda and attach dispatch window.

#### <C-c C-c> in agenda calls org-agenda-set-tags

Both <C-c C-q> and <C-c C-c> set the tags of the headline in the Org buffer. Both keybindings are now available from the agenda too.

#### Allow to use an empty HTML extension

Using (setq org-html-extension "") or setting the HTML extension in any fashion will produce the expected output, with no trailing period to the resulting HTML file.

#### Handle repeated tasks with .+ type and hours step

A task using a .+ repeater and hours step is repeated starting from now. E.g.,

,** TODO Wash my hands
Marking this DONE shifts the date to exactly one hour from now.


#### The format of equation reference in HTML export can now be specified

By default, HTML (via MathJax) and LaTeX export equation references using different commands. LaTeX must use \ref{%s} because it is used for all labels; however, HTML (via MathJax) uses \eqref{%s} for equations producing inconsistent output. New option org-html-equation-reference-format sets the command used in HTML export.

#### ob-haskell.el supports compilation with :compile header argument

By default, Haskell blocks are interpreted. By adding :compile yes to a Haskell source block, it will be compiled, executed and the results will be displayed.

#### Support for org-edit-special with LaTeX fragments

Calling org-edit-special on an inline LaTeX fragment calls a new function, org-edit-latex-fragment. This functions in a comparable manner to editing inline source blocks, bringing up a minibuffer set to LaTeX mode. The math-mode deliminators are read only.

#### New org-refile.el` file

Org refile variables and functions have been moved to a new file.

#### The end of a 7 years old bug

This bug originally reported by Matt Lundin and investigated by Andrew Hyatt has been fixed. Thanks to both of them.
