 Fixes since v1.6.1.3
 --------------------

+* .gitignore learned to handle backslash as a quoting mechanism for
+  comment introduction character "#".
+  This fix was first merged to 1.6.2.1.
+
 * "git fast-export" produced wrong output with some parents missing from
  commits, when the history is clock-skewed.

 * "git fast-import" sometimes failed to read back objects it just wrote
  out and aborted, because it failed to flush stale cached data.

+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+  deciding to descend into a subdirectory but they did not match the
+  individual paths correctly.  This caused pathspecs "abc/d ab" to match
+  "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+  and then "ab" incorrectly matched "abc/0" when it shouldn't).
+  This fix was first merged to 1.6.2.3.
+
+* import-zips script (in contrib) did not compute the common directory
+  prefix correctly.
+  This fix was first merged to 1.6.2.2.
+
+* "git init" segfaulted when given an overlong template location via
+  the --template= option.
+  This fix was first merged to 1.6.2.4.
+
 * "git repack" did not error out when necessary object was missing in the
  repository.

+* git-repack (invoked from git-gc) did not work as nicely as it should in
+  a repository that borrows objects from neighbours via alternates
+  mechanism especially when some packs are marked with the ".keep" flag
+  to prevent them from being repacked.
+  This fix was first merged to 1.6.2.3.
+
 Also includes minor documentation fixes and updates.

+==========================
+
+Fixes since v1.6.2.4
+--------------------
+
+* "git apply" mishandled if you fed a git generated patch that renames
+  file A to B and file B to A at the same time.
+
+* "git diff -c -p" (and "diff --cc") did not expect to see submodule
+  differences and instead refused to work.
+
+* "git grep -e '('" segfaulted, instead of diagnosing a mismatched
+  parentheses error.
+
+* "git fetch" generated packs with offset-delta encoding when both ends of
+  the connection are capable of producing one; this cannot be read by
+  ancient git and the user should be able to disable this by setting
+  repack.usedeltabaseoffset configuration to false.

 If your description starts to get too long, that's a sign that you
 probably need to split up your commit to finer grained pieces.
+That being said, patches which plainly describe the things that

+the code, are the most beautiful patches.  Descriptions that summarise
