Emacs 29.2 released

Emacs 29.2 released

[Eli Zaretskii]

Hi!

Version 29.2 of Emacs, the extensible text editor, should now
be available from your nearest GNU mirror:

   https://ftpmirror.gnu.org/emacs/emacs-29.2.tar.xz
   https://ftpmirror.gnu.org/emacs/emacs-29.2.tar.gz

The tarballs are signed; you can get the corresponding PGP signature
files at:

   https://ftpmirror.gnu.org/emacs/emacs-29.2.tar.xz.sig
   https://ftpmirror.gnu.org/emacs/emacs-29.2.tar.gz.sig

You can choose a mirror explicitly from the list at:
  https://www.gnu.org/prep/ftp.html

Mirrors may take some time to update; the main GNU ftp server is at:
  https://ftp.gnu.org/gnu/emacs/

To verify that the downloaded tarball is intact, download both the
tarball and the corresponding .sig file, and run this command:

  gpg --verify emacs-29.2.tar.xz.sig

(and similarly for emacs-29.2.tar.gz, if you download that format).

If the GPG command fails because you don't have the required PGP
public key, run this command to import the key:

  gpg --keyserver keyserver.ubuntu.com --recv-keys \
    17E90D521672C04631B1183EE78DAE0F3115E06B

Alternative keyservers to try are pgp.mit.edu and keys.openpgp.org.

You can also run sha1sum or sha256sum and confirm that these
checksums match:

SHA1 emacs-29.2.tar.gz
a3751a1dc9c68c93e00f8935603f48d7b1804360
SHA1 emacs-29.2.tar.xz
77e16923012960960c2d8fd8cc92db70f8a366b9

SHA256 emacs-29.2.tar.gz
ac8773eb17d8b3c0c4a3bccbb478f7c359266b458563f9a5e2c23c53c05e4e59
SHA256 emacs-29.2.tar.xz
7d3d2448988720bf4bf57ad77a5a08bf22df26160f90507a841ba986be2670dc

Emacs 29.2 is a bug-fix release, with no new features with respect to
Emacs 29.1.

For the complete list of changes and the people who made them, see the
various ChangeLog files in the source distribution.  For a summary of
all the people who have contributed to Emacs, see the etc/AUTHORS
file.

The online manuals and website will be updated shortly.

Printed copies of the Emacs manual are available for purchase from the
Free Software Foundation's online store at:

Thank you!

How are the DJGPP packages generated?  I have configured a machine to
build the MS-DOS port every so often, which perhaps could be repurposed
to also generate such releases.

What do you mean by "the DJGPP packages" in this context?

Packages assembled in the same format as the packages available on the
DJGPP FTP site, which are ZIP archives that can be unpacked in any
directory and executed directly from there.

Thanks.

They are just ZIP archives produced from a directory where Emacs was
built, plus a few files that describe the package.  I will probably
produce the files for Emacs 29.2 in a couple of days.

pdumper.c Wstringop-overflow warnings with CFLAGS="-O3" [Re: Emacs 29.2 released]

Thank you Eli for your stalwart maintenance of Emacs and to everyone
else who has contributed recently (and, indeed, ever).

Building Emacs 29.2 with CFLAGS="-O3" I get four Wstringop-overflow
warnings in pdumper.c (see below).  Can I (as an Emacs user) safely
ignore these warnings?  Note: I don't get these warnings with
CFLAGS="-O2".

My version of gcc is:

  gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4)

The four warnings are:

  In function ‘dump_field_lv_or_rawptr’,
      inlined from ‘dump_field_lv_rawptr’ at pdumper.c:1882:3,

If someone wants to investigate these warnings, please do.  My sincere
suggestion is not to build Emacs with -O3 regardless: it is not going
to give you a faster Emacs, and might even give you a slower Emacs.
That's because the inner-most loops in Emacs are very large, and the
optimization techniques used by -O3 are likely not to work well, while
at the same time the excessive inlining might make those loops larger
and thus overflow the CPU caches, which slows down code execution.

Thanks.

Does this mean, the emacs-29 branch is reopen for further commits? Are
there plans for an Emacs 29.3?

I'd like to sync recent Tramp changes (available already via GNU ELPA)
into that branch.

Best regards, Michael.

It was never closed.  But since this is still a release branch, only
bug-fix changes should be installed that are either very safe or fix
very urgent serious problems.

> Are there plans for an Emacs 29.3?

Not yet.  I think we should only consider 29.3 if significant problems
are reported in 29.2 that require quick remediation.

Are they safe enough and/or fix serious problems?

We're speaking about Tramp's 2.6 branch. Since Emacs 29.0.90 it sees
only this kind of changes. New features go to Tramp 2.7.

Then please go ahead, and thanks.
