 All of the fixes in v1.7.3.X maintenance series are included in this
 release, unless otherwise noted.
 
- * Smart HTTP transport used to incorrectly retry redirected POST
-   request with GET request (311e2ea006).
-
- * "git apply" did not correctly handle patches that only change modes
-   if told to apply while stripping leading paths with -p option (aae1f6ac).
-
- * "git apply" can deal with patches with timezone formatted with a
-   colon between the hours and minutes part (e.g. "-08:00" instead of
-   "-0800").
-
  * "git checkout" removed an untracked file "foo" from the working
     tree when switching to a branch that contains a tracked path
     "foo/bar".  Prevent this, just like the case where the conflicting
     path were "foo" (c752e7f..7980872d).
 
- * "git diff --check" reported an incorrect line number for added
-   blank lines at the end of file (8837d335).
-
  * "git log --author=me --author=her" did not find commits written by
    me or by her; instead it looked for commits written by me and by
    her, which is impossible.
