* "git fast-import" learned that "--signed-commits=<how>" option that
corresponds to that of "git fast-export".
+ * Marking a hunk 'selected' in "git add -p" and then splitting made
+ all the split pieces 'selected'; this has been changed to make them
+ all 'undecided', which gives better end-user experience.
+
+ * Configuration variables that take a pathname as a value
+ (e.g. blame.ignorerevsfile) can be marked as optional by prefixing
+ ":(optoinal)" before its value.
+
Performance, Internal Implementation, Development Support etc.
--------------------------------------------------------------
* Dip our toes a bit to (optionally) use Rust implemented helper
called from our C code.
+ * Documentation for "git log --pretty" options has been updated
+ to make it easier to translate.
+
Fixes since v2.51
-----------------
carefully.
(merge 466a3a1afd kn/reftable-consistency-checks later to maint).
+ * A lot of code clean-up of xdiff.
+ Split out of a larger topic.
+ (merge 8b9c5d2e3a en/xdiff-cleanup later to maint).
+
+ * "git format-patch --range-diff=... --notes=..." did not drive the
+ underlying range-diff with correct --notes parameter, ending up
+ comparing with different set of notes from its main patch output
+ you would get from "git format-patch --notes=..." for a singleton
+ patch.
+
* Other code cleanup, docfix, build fix, etc.
