Discussed in
https://lists.gnu.org/archive/html/emacs-devel/2025-12/msg00903.html.
* lisp/progmodes/project.el (project-files) <vc>: Look up the
value of 'project-vc-ignores' inside DIR rather than project root.
This allows this variable to be applied in external dirs as well.
(project-ignores) <vc>: Do likewise.
(project--value-in-dir): Ensure that DIR has a trailing slash.
The caller might pass the value without slash if produced
differently.
* test/lisp/progmodes/project-tests.el
(project-vc-ignores-in-external-directory): New test.
(project-vc-supports-files-in-subdirectory): Update the test,
considering the subtle change in behavior: the directory DIR
directly includes a .dir-locals.el which sets project-vc-ignores,
which wasn't previously applied because it wasn't set in the root.
There are going to be new outstanding changes commands that will
deal in logs, not diffs.
* doc/emacs/vc1-xtra.texi (Outgoing Base Diffs): Rename and
retitle node ...
(Outstanding Changes): ... to this.
* lisp/emacs-lisp/track-changes.el (track-changes-undo-only): New var.
(track-changes-fetch): Bind it.
(track-changes--state): New slot `undo`.
(track-changes--after): Set it.
* lisp/vc/diff-mode.el (diff--track-changes-function): Use the
new var.
* doc/lispref/text.texi (Tracking changes): Mention
`track-changes-undo-only`.
* lisp/vc/vc.el (vc--read-branch-to-log): New function.
(vc-print-root-branch-log): Rewrite to use
vc--read-branch-to-log and vc--with-backend-in-rootdir.
(vc-print-fileset-branch-log): New command.
* lisp/vc/vc-dir.el (vc-dir-mode-map):
* lisp/vc/vc-hooks.el (vc-prefix-map):
(vc-menu-map): Bind it.
* doc/emacs/maintaining.texi (VC Change Log):
* etc/NEWS: Document it.
Zero-length strings are just 'empty'; 'null' can be confusing in several
ways.
* lisp/subr.el (split-string, string-lines):
* doc/lispref/strings.texi (Creating Strings):
Change argument names from 'omit-nulls' to 'omit-empty'.
* doc/lispref/strings.texi (Creating Strings):
* lisp/subr.el (split-string):
Make it clear that the SEPARATORS argument should not match the empty
string, since the behaviour was entirely an artefact of the original
implementation in this case; it makes little sense otherwise.
Clean up the examples for conciseness and do not waste space on
irrelevant details.
Some of the fixes are to continue to use American
rather than British spelling.

Fix misspelling of ‘zone--buffer-encrypted-p’.
* lisp/progmodes/csharp-mode.el (csharp-ts-mode-faces):

* lisp/vc/vc.el (vc-clonable-backends-custom-type):
Rename from vc-cloneable-backends-custom-type,
leaving an alias behind.

(bytecomp-tests--warn-arity-non-compiled-callee):
Rename from bytecomp-tests--warn-arity-noncompiled-callee.
(bytecomp-test-defface-spec): Reword a deliberate misspelling
of “default” that is so common I don’t want it to pollute the
spelling dictionary.
* test/lisp/emacs-lisp/package-vc-tests.el:
(package-vc-tests-preserve-artifacts):
Rename from package-vc-tests-preserve-artifacts.
* test/lisp/eshell/em-prompt-tests.el:

don’t want it to pollute the spelling dictionary.
These produce the binary representation of a number.
'%#b' and '%#B' prefix with '0b' and '0B', respectively.
(bug#79990)
* etc/NEWS: Announce change.
* doc/lispref/strings.texi (Formatting Strings): Describe new format
specs and add to comment on reconstructing the value with 'read'.
* src/editfns.c (format): Update doc string.
(styled_format): Add support for '%b' and '%B'. To remain
portable, avoid use of 'sprintf' by converting by hand.
* test/src/editfns-tests.el (format-binary-zero, format-binary-floats)
(format-binary-nonzero-integers): Add tests.
(read-large-integer): Add binary test cases.

This experimental variable caused more trouble than it cured:
it was rarely used, and when used it tended to be used incorrectly.

mutable if containing substitions, but that is simply not true;
they should always be treated as non-mutable.

In 2014, the Universal House of Justice announced modifications to
the Badí' calendar to bring it more in line with its original design.
>From 172 BE (Naw-Rúz 2015) onwards, Naw-Rúz is determined by the
vernal equinox as observed from Tehran, and the Twin Holy Birthdays
are calculated from the eighth new moon after Naw-Rúz.

description to mention the 2014 reform, Ayyám-i-Há, and the

astronomical calculations.
