 Please send Org bug reports to mailto:emacs-orgmode@gnu.org.
 
+* Version 9.4
+** Incompatible changes
+*** Possibly broken internal file links: please check and fix
+
+A bug has been affecting internal links to headlines, like
+
+: [[*Headline][A link to a headline]]
+
+Storing a link to a headline may have been broken in your setup and
+those links may appear as
+
+: [[*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:
+
+#+begin_src emacs-lisp
+(defun org-fix-links ()
+  "Fix ill-formatted internal links.
+E.g. replace [[*TODO Headline][headline]] by [[*Headline][headline]].
+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))
+                     (looking-at-p org-link-bracket-re))
+                   (y-or-n-p "Fix link (remove TODO keyword)? "))

+#+end_src
+
+*** 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
+
+#+PRIORITIES: 1 10 5
+
+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.
+
+*** New step value =semimonth= accepted for clock tables
+
+*** 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:
+
+#+begin_src emacs-lisp
+(add-hook 'org-mode-hook (lambda () (electric-indent-local-mode -1)))
+#+end_src
+
+Alternatively, if you wish to keep =RET= as the "smart-return" key,
+but dislike Org's default indentation of sections, you may prefer to
+customize ~org-adapt-indentation~ to either =nil= or ='headline-data=.
+
+*** =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 [[https://github.com/clojure-emacs/inf-clojure][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 [[https://github.com/clojure-emacs/cider][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 [[https://code.orgmode.org/bzg/org-mode/commit/b186d1d7][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-show-notification-timeout~
+
+This option will add a timeout to notifications.
+
+*** 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 [[https://orgmode.org/manual/Results-of-Evaluation.html][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 [[https://orgmode.org/list/CA+A2iZaziAfMeGpBqL6qGrzrWEVvLvC0DUw++T4gCF3NGuW-DQ@mail.gmail.com/][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 ~org-columns-set-tags-or-toggle~
+
+See [[*~org-columns-toggle-or-columns-quit~]].
+
+*** 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.
+
+*** New function ~org-collect-keywords~
+*** 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.,
+
+#+begin_example
+,,** TODO Wash my hands
+   DEADLINE: <2019-04-05 08:00 Sun .+1h>
+   Marking this DONE shifts the date to exactly one hour from now.
+#+end_example
+
+*** 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.
+
+*** ~org-capture-current-plist~ is now accessible during ~org-capture-mode-hook~
+*** 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 [[https://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00072.html][originally reported]] by Matt Lundin and investigated by Andrew
+Hyatt has been fixed.  Thanks to both of them.
