3.1.10

[3.1.10] - 2023-01-13 Henri Menke

Even though this release is not too heavy on user-facing additions it has seen a
lot of contributed changes. Thanks to everyone who volunteered their time!

BREAKING CHANGES

• \pgfversiondatetime and \pgfrevisiondatetime have been removed.
  \pgfversiondate and \pgfrevisiondate now use the format YYYY-MM-DD.
  \pgfrevision{,date} and \pgfversion{,date} are synonyms for now, but the
  revision should eventually gain back its original meaning. However, as of now
  this is not supported by l3build.
• Many operations in pgfkeys used to use \csname directly which lets the
  given csname become \relax in case it wasn't defined. This resulted in some
  leakage of accidentally \relaxed keys into the global scope. This has been
  cleaned up a little. To preserve compatibility macros that used to expand to a
  \relaxed csname now expand to a primitive \relax. This affects the
  user-level commands \pgfkeysgetvalue and \pgfkeysgetvalueof. For the
  former the change should not be visible except for the number of expansions
  required. For \pgfkeysgetvalueof, however, the behavior is manifestly
  different in that it will now expand to an alias for the primitive \relax in
  case the value is undefined instead of a \relaxed csname. It has always been
  semantically wrong to assign to the result of \pgfkeysgetvalueof, but now it
  will have undesired side-effects. Therefore this change is breaking.
• The textures and vtex drivers have been deprecated. Both engines are no
  longer in active development and lack eTeX features which are required for
  quite some time in PGF.
• The file pgfutil-common-lists.tex is deprecated and therefore no longer
  \input by pgfutil-common.tex. The macros from this file are specifically
  meant for pgfplots and are not used in PGF at all.

Added

• l3build support for packaging PGF/TikZ
• Add Matrix chat to README
• Add rhombic polihedra #1022
• Add Developer Certificate of Origin (DCO) to Pull Request template and enforce
• Add test set for graphdrawing (gd)
• pgfkeys gained support for loading libraries
• Add dependabot to keep GitHub Actions up to date

Fixed

• Wrap logic gate symbol in \pgfinterruptpicture for shapes in library
  shapes.gates.logic.IEC
• Remove superfluous ; for shape arrow box
• Remove superfluous /utils/exec in animations
• Gobble \pgf@stop when parsing finishes in animations

• Protect against comma in pgfkeys arguments #389
• Let active " expand to non-active " in pgfmath #1062
• Protect against comma in /tikz/rotate fit argument and make it
  eagerly evaluated #1071

3.1.9a

Emergency release to fix pgfplots which depends on unreleased parts of PGF.

3.1.9

Bug fixes

This release introduces a fix for blend mode with the dvips driver and
improvements for handling expandable material that appears on a path.

3.1.8b

Hotfix for handling of TeX conditionals on a path. We can't forward \relax and
frozen \relax through the parser because there is existing code that relies on
this.

The recommendation is to use expandable conditionals where possible.

3.1.8a

Hotfix for the new topaths handling. One instance did not yet properly
preserve relative coordinates.

3.1.8

BREAKING CHANGES

If a topath is bent by any of the in=, out=, bend=, etc. options, a Bezier
curve is constructed in the background. To infer the positions of the control
points the start and end coordinate are converted to absolute coordinates.
However, this has the effect that subsequent points on the path think that the
endpoint of the topath was absolute which can lead to counter-intuitive path
construction, e.g.

\draw (2,0) to[out=0,in=180] +(1,0) -- ++(0,-1) -- +(1,0);

If old code relies on this behavior, this drawing will silently break! Please
open an issue if you rely on this.

Bug fixes

This release introduces a fix for path handling which concerns expansion of
tokens on the path in particular with respect to conditional. Previously when
the expansion of a conditonal resulted in a frozen \relax the parser would just
give up. Now the parser will skip over the frozen \relax and continue to
expand tokens. Whether this will result in a meaningful expansion is up to the
user.

This release also includes other bug fixes. On GitHub you can click the commit
hashes and the issue numbers to get to the fix and the ticket, respectively.

3.1.7a

Bug fixes

Another issue with the new LaTeX hook mechanism surfaced in the external
library which is being worked around now.

This release also includes other bug fixes. On GitHub you can click the commit
hashes and the issue numbers to get to the fix and the ticket, respectively.

3.1.7

Bug fixes

Mostly spurious spaces have been fixed and some code has been adapted to work with the latest LaTeX release. In principle it should still be backwards compatible to older LaTeX releases but regressions cannot be excluded.

Some other bug fixes:

67295ec #946
74b2cc3 #934
8beaf97 #928
bf46600 #654
1e8ee72 #930

3.1.6a

Hotfix for intersections library. In the last version \pgfintersectionoflines was set to always return the intersection in the untransformed coordinate system #889. This however broke the interplay with other coordinate transformations and had to be reverted.
