+## [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 `\relax`ed keys into the global scope. This has been
+ cleaned up a little. To preserve compatibility macros that used to expand to a
+ `\relax`ed 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 `\relax`ed 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.
+
