A Portable Graphic Format for TeX
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!
\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.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.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.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.graphdrawing (gd)\pgfinterruptpicture for shapes in library

Emergency release to fix pgfplots which depends on unreleased parts of PGF.
This release introduces a fix for blend mode with the dvips driver and improvements for handling expandable material that appears on a path.
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.
Hotfix for the new topaths handling. One instance did not yet properly preserve relative coordinates.
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.
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.

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

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:

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.
This release stands in the name of the two contributors Alexander Grahn and Yukai Chou without whom this release would not have been nearly as great. Thank you very much!
In the last version, in an attempt to fix updating local bounding box in a clipping scope the \pgf@path@size@hook in \pgf@protocolsizes was set to be executed unconditionally. Unfortunately, this broke all other uses of local bounding box and has been reverted. If you need to use local bounding box in a clipping scope, use the overlay option.
The recent Ghostscript version 9.53 has changed the primitives for transparency, blend mode, and transparency groups. These are now supported by PGF and should in principle go unnoticed by the user. (Thanks Alexander Grahn!)
\pgfintersectionoflines will now always return the intersection in the untransformed coordinate system. This however requires an additional \pgftransforminvert which comes with a loss of precision and can potentially lead to Dimension too large errors in edge cases.
PGF now supports the new hook management that will be introduced in LaTeX 2020/10/01. While this should not lead to any noticeable changes, please look out for breakages with overlays and the current page nodes. Please report problems on the PGF or LaTeX issue trackers.
You can read about these new features in the manual:
PS-3 functional shading, opacity masks (fadings) and image masks for dvips. (Thanks Alexander Grahn!)
The dvisvgm4ht driver developed by Michal Hoftich has been merged into PGF/TikZ.
The pgfparser module has been slightly refactored such that it can be used without loading all of PGF.
The order in which the inner styles are applied in a \matrix is now configurable. #867
The file pgfmanual-en-macros.tex is developed specifically for typesetting the PGF manual, however, many other package developers have found it useful and made good use of it. To this end, we now install pgfmanual-en-macros.tex into a directory that is searched by kpathsea such that developers no longer have to copy the file into their own distribution.
The CI system was switched from Travis CI to GitHub Actions for better integration with GitHub and direct deployment of build artefacts to the status page.
bbox library introduced in PGF 3.1.5 was removed. I further recommend that if there are files containing bbox code left over from a previous version that these are removed to avoid potential issues.Lots of bug fixes.
