 * "--pretty=<style>" option to the log family of commands can now be

 Here are fixes that this release has, but have not been backported to
 v1.6.2.X series.
 
+* "git diff --pickaxe-regexp" did not count overlapping matches
+  correctly (backport by cherry-picking 50fd699).
+
+* "git-fetch" in a repository that was not cloned from anywhere said
+  it cannot find 'origin', which was hard to understand for new people.
+
+* git-gc spent excessive amount of time to decide if an object appears
+  in a locally existing pack (if needed, backport by merging 69e020a).
+
+* "git-ls-files --deleted" did not work well with GIT_DIR&GIT_WORK_TREE
+  (backport by cherry-picking 8ad3dae).
+
+* "git-read-tree A B C..." without -m option has been broken for a long time
+  (backport by merging jc/maint-1.6.0-read-tree-overlay)
+
 * 'git-submodule add' did not tolerate extra slashes and ./ in the
   path it accepted from the command line; it now is more lenient
  (if needed, backport by merging db75ada).
