This was a proposal by Samuel Wales. After the user selected a
refiles target, we make sure that the fully qualified target is in the
history, so that next time, UP will bring back exactly this target.
Before this patch the completion mechanism was this: TAB let's you
complete through link prefixes (gnus: file: bbdb: ...) then RET allows
completion if a completion mechanism is available for the chosen prefix.
Navigating through the history of stored links was a separate process,
available through the up/down M-n/M-p keys.
Now TAB not only completes through link prefixes but also through stored
links. This behavior matches other Emacs completion mechanisms a bit
more closely.
If you have a TODO keyword like "DELEGATED" and an entry like
"* Delegated this stuff to X", then you want this entry to be
in the list of possible targets. For that we need to distinguish
between DELEGATED as a keyword and "Delegated" as a simple word,
so (case-fold-search nil) seems relevant.
This default to t, so the default behavior of org-mode doesn't
change. But the user might want to keep at least one blank line
at the end of the remembered subtree, this option lets her do it.
This hook is called in org-clock-in earlier than the existing
org-clock-in-hook. This is useful for functions that need to
modify the Effort property, for example.
`org-export-latex-first-lines' was rather stupid and would
discard the end of the region with the region was active.
Thanks to Holst Thomas for this bug report.

When changing the publishing setup, old timestamp files can be left
behind. Forcing publishing of all projects with `C-u C-c C-e E'
will remove all existing timestamp files.
Many different people want to set many different variables in a
buffer-local way for export. This cannot be done with file variables,
because the Org buffer is not current while the exporter is running.
Lots of variables can be set with the #+OPTIONS lines, but finding
abbreviations goes only so far.
Therefore we have now a general mechanism that can be used to bind
variables during export operations.
a line like: #+BIND: variable value
will bind the variable to value. For example,
the line
>> #+OPTIONS: toc:nil
can now equivalently be written as
>> #+BIND: org-export-with-toc nil

Customize the new variable org-footnote-auto-adjust or use the STARTUP
option fnadjust to get automatic renumbering and sorting of footnotes
after each insertion/deletion.
This commit implements better support for publishing the same file in
multiple ways. For example when publishing a Org file both as HTML
and as a plain text or htmlized source file.
It does this by including information about the target directory and
about the publishing function used into the hash that is used as a
file name to keep a time stamp.
Agenda bulk commands on marked entries now can also set the scheduling
date or a deadline. Normally, all entries will be set to the
specified date. However, when writing the change as "++5d" or "++2w",
then each time stamp will independently be shifted by that amount.
This commit adds a new action to the footnote actions:
It allows to renumber footnote marks that have the simple form
fn:N where N is a number. After this action, numbers will start from
1 and increase through the document.
TAB now cycles visibility in plain lists if the cursor is in a plain
list. This corresponds now to the new default value `t' of
`org-cycle-include-plain-lists'. If you want to treat plain list
items as part of the outline hierarchy during cycling of outline
headings (this is what a `t' value used to mean), set this variable to
`integrate'.
- test on line 312 failed because these methods returned a string instead

- curl needs --silent, so that progress messages don't interrupt content

Instead, remove HTTP headers right after feed buffer is populated.
Some propel process LaTeX filed not directly to pdf, but go
through dvi and then to ps or pdf. In that case, allowed images
are ps and eps files, not pdf and jpg.
This commit adds the two extensions, so that export using that
alternative path can be supported better. However, it is up to the
user to make sure that the images are actually compatible with the
backend.

This behavior is a loft-over from the old days, and I am changing
this now.
This commit implements refiling directly from the agenda.
It also implements a mechanism for selecting a number of entries in
the agenda and then executing a command on all of them. Possible
actions include archive, refile, todo state setting, and more.

This commit introduces a new variable `org-export-table-row-tags'
that can be used for this and similar purposes. For the example
of the poster, one could use:
(setq org-export-table-row-tags
(cons '(if head "<tr>"
(if (= (mod nline 2) 1)
"<tr class=\"d1\">"
"<tr class=\"d0\">"))
"</tr>"))
Clicking on the clock in the mode line now pops up a menu with
clocking options.
A new command `C-c C-x C-e' allows to set or change the effort
estimate of the task currently being clocked. This is mainly useful
when using an alert notification when the task should be finished.
Based on a patch by Konstantin Antipin.
This commit adds a new hook `org-src-mode-hook'.
The Hook run after Org switched a source code snippet to
its Emacs mode. This hook will run
- when editing a source code snippet with \"C-c '\".
- When formatting a source code snippet for export with htmlize.
You may want to use this hook for example to turn off `outline-minor-mode'
or similar things which you want to have when editing a source code file,
but which mess up the display of a snippet in Org exported files.
As the export preprocessor removes indentation from indented blocks,
this causes conflicts about interpreting indentation as list
termination. Now the original indentation is stored in a text
property, so hopefully the exporters can make use of this information
in due time.
When the agenda buffer for an agenda series is created, this was so
far done without the options of the custom agenda command in place.
This meant that some options would not take effect, because the only
place where that did would have an effect was during creation of that
buffer.
This commit makes sure that the global options of an agenda series are
in fact in place when the buffer is created.
This commit changes which time is shown in the mode line while
clocking. Normally this will now be the total time ever clocked on
this task and its children.
However, when the task is a repeating one, only the time since the
last reset of the task will be shown. The time of the last reset is
now recorded in a LAST_REPEAT property.
You can also set the CLOCK_MODELINE_TOTAL property to the value
"current" to only show the current clocking instance. Or it may be
the value "today", to only add up the time spent today on this task.
Other possible values are "repeat", "all", or "auto".
Finally, you can set your default for this property with
`org-clock-modeline-total'.
The content of blocks like #+begin_example will be marked with a
separate face. That same face is also used for single lines
introducing text for specific backends.
This commit introduces two new variables:
- org-treat-insert-todo-heading-as-state-change
Default is nil. When set to t, adding a new TODO item will be done
by adding an item and the executing an "official" state change which
potentially will trigger state logging.
- org-treat-S-cursor-todo-seletion-as-state-change
Default is t. When set to nil, selecting a TODO state with
S-left/right will not trigger logging, only selecting a new state
with `C-c C-t'. I actually like this a lot and would even consider
making this the default.

All export commands now push the result to the kill ring by default.
This is subject to the variable `org-export-push-to-kill-ring'.
Also, this commit adds a new variable
`org-export-show-temporary-export-buffer' which can be used to turn
off the display of the temporary buffer containing the exported text.
Since this stuff is now automatically pushed onto the kill ring, some
people might prefer not to see this buffer.

Setting the new option `org-hierarchical-todo-statistics' to nil will
make TODO statistics to be computed recursively. This means, not only
the direct children of a node contribute to its TODO statistics, but
the entire subtree.
You can also set the COOKIE_DATA property and add the word "recursive"
there to get recursive statistics for a specific tree.
Publishing a project with prefix argument to
force publishing was broken. Actually, the entire interactive side of
this function was implemented badly. Fixed now.

The better approach is clearly to allow several buffers, now

This bug was due to a missing save-match-data around a call to
org-get-tags-at. However, when studying this bug it turned out
that explicitly checking for the archive tag is not needed,
because we already have a call to `org-agenda-skip' in the same
loop.

This commit applies Beanjamin's patch
There is now a new export function, `org-export-as-org', which
basically creates a copy of the Org file with things like archived
trees, commented trees, and trees deselected by export tags,
stripped.
This commit adds:
{{{date(FORMAT)}}} current date/time, formatted with
`format-time-string'
{{{modification-time(FORMAT)}}} date/time of last modification of
file, formatted with `format-time-string'
{{{input-file}}} the file name of the source Org file.

This commit implements this, when the value of
`org-icalendar-include-todo' is the symbol `unblocked'.
The commit implements a general mechanism for providing special
(e.g. completion) support for specific link types when entering links
with `C-c C-l'. After calling `C-c C-l', you may now press RET after
inserting a link prefix, and Org will look for a function
`org-PREFIX-complete-link'. Such functions may be defined for any
link types, including link abbreviations. Currently, Org has
`org-file-complete-link' for file name completion, and
`org-bbdb-complete-link' for completion of record names from BBDB.

This was a bug, fixed now.
Editing source code examples and pictures is not done in a truly
separate buffer, not in an indirect buffer. Indirect buffers had
caused problems with fontification, for example.

It is actually the correct way to do this, and I have
implemented this change.

There is now, `C-c C-e A'.
This commit also implements commands
- org-export-as-ascii-to-buffer
- org-replace-region-by-ascii
- org-export-region-as-ascii
which are similar to what is available for HTML and LaTeX.
`C-c C-e A' used to be the key for publishing all projects.
This functionality has now been moved to `C-c C-e E'.

This situation is now avoided by forcing the selection of a valid

Chris Gray had the idea to have arbitrary blocks turned in LaTeX

There is now a better error message when either the latex or the

This commit adds a new option
`org-agenda-skip-additional-timestamps-same-entry'. When set
to t, an entry that has multiple active time stamps will get
multiple lines in the agenda.

The variable `org-refile-target-verify-function' can be set to a
function that will be called to verify a refile target. The function
must return t if the target is valid.
Users can now define custom IDs for use in HTML export.
These IDs are stores as property CUSTOM_ID. When present, HTML will
prefer using these over automatic targets like "sec-N.M".
