- * When an object "$tree:$path" does not exist, if $path does exist in the
-   subtree of $tree that corresponds to the subdirectory the user is in,
-   git now suggests using "$tree:./$path" in addition to the advice to use
-   the full path from the root of the working tree.
-
  * "git blame" learned "--abbrev[=<n>]" option to control the minimum
    number of hexdigits shown for commit object names.
 
- * "git clean" used to fail on an empty directory that is not readable,
-   even though rmdir(2) could remove such a directory.  Now we attempt it
-   as the last resort.
-
  * "git diff -C -C" used to disable the rename detection entirely when
    there are too many copy candidate paths in the tree; now it falls
    back to "-C" when doing so would keep the copy candidate paths

  * "git merge" learned "-" as a short-hand for "the previous branch", just
    like the way "git checkout -" works.
 
- * "git pack-object" now takes core.bigfilethreashold into account, just
-   like fast-imoprt does.
-
- * "git reflog" allows options like "--format=.." to be given.
-
- * "git stash apply" can now apply to a working tree with changes as long
-   as there is no overlapping change as the stash being applied.
+ * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
+   commits separately, producing more a useful output.
 
  * "git submodule update" learned "--force" option to get rid of local
    changes in submodules and replace them with the up-to-date version.
 
- * "git stash apply @{99999}" now is diagnosed as an error, unless you
-   really have that many stash entries.
+ * Compressed tarball gitweb generates is made without the timestamp of
+   the tarball generation; snapshot from the same tree should result in
+   a same tarball.
 
 Also contains various documentation updates.

- * The "--dirstat" option of "diff" family of commands used to totally

- * The "--dirstat" option of "diff" family of commands used to use the

    source candidate, which made no sense.
