Updates since v2.26
-------------------
+Backward compatibility notes
+
+ * When "git describe C" finds that commit C is pointed by a signed or
+ annotated tag, which records T as its tagname in the object, the
+ command gives T as its answer. Even if the user renames or moves
+ such a tag from its natural location in the "refs/tags/" hierarchy,
+ "git describe C" would still give T as the answer, but in such a
+ case "git show T^0" would no longer work as expected. There may be
+ nothing at "refs/tags/T" or even worse there may be a different tag
+ instead.
+
+ Starting from this version, "git describe" will always use the
+ "long" version, as if the "--long" option were given, when giving
+ its output based on such a misplaced tag to work around the problem.
+
+ * "git pull" issues a warning message until the pull.rebase
+ configuration variable is explicitly given, which some existing
+ users may find annoying---those who prefer not to rebase need to
+ set the variable to false to squelch the warning.
+
+
UI, Workflows & Features
* A handful of options to configure SSL when talking to proxies have
been added.
+ * Smudge/clean conversion filters are now given more information
+ (e.g. the object of the tree-ish in which the blob being converted
+ appears, in addition to its path, which has already been given).
+
+ * When "git describe C" finds an annotated tag with tagname A to be
+ the best name to explain commit C, and the tag is stored in a
+ "wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the
+ command gave a warning message but used A (not B) to describe C.
+ If C is exactly at the tag, the describe output would be "A", but
+ "git rev-parse A^0" would not be equal as "git rev-parse C^0". The
+ behavior of the command has been changed to use the "long" form
+ i.e. A-0-gOBJECTNAME, which is correctly interpreted by rev-parse.
+
+ * "git pull" learned to warn when no pull.rebase configuration
+ exists, and neither --[no-]rebase nor --ff-only is given (which
+ would result a merge).
+
Performance, Internal Implementation, Development Support etc.
* The advise API has been revamped to allow more systematic enumeration of
advice knobs in the future.
+ * SHA-256 transition continues.
+
+ * The code to interface with GnuPG has been refactored.
+
+ * "git stash" has kept an escape hatch to use the scripted version
+ for a few releases, which got stale. It has been removed.
