 Fixes since v1.7.9.1
 --------------------
 
+ * Bash completion script (in contrib/) did not like a pattern that
+   begins with a dash to be passed to __git_ps1 helper function.
+
+ * Adaptation of the bash completion script (in contrib/) for zsh
+   incorrectly listed all subcommands when "git <TAB><TAB>" was given
+   to ask for list of porcelain subcommands.
+
+ * The build procedure for profile-directed optimized binary was not
+   working very well.
+
+ * Some systems need to explicitly link -lcharset to get locale_charset().
+
+ * t5541 ignored user-supplied port number used for HTTP server testing.
+
  * The error message emitted when we see an empty loose object was
    not phrased correctly.

    input when GIT_ASKPASS is set but does not work (e.g. lack of X
    with GUI askpass helper).
 
+ * We failed to give the true terminal width to any subcommand when
+   they are invoked with the pager, i.e. "git -p cmd".
+
  * map_user() was not rewriting its output correctly, which resulted
    in the user visible symptom that "git blame -e" sometimes showed
    excess '>' at the end of email addresses.
 
  * "git checkout -b" did not allow switching out of an unborn branch.
 
+ * When you have both .../foo and .../foo.git, "git clone .../foo" did not
+   favor the former but the latter.
+
  * "git commit" refused to create a commit when entries added with
    "add -N" remained in the index, without telling Git what their content
    in the next commit should be. We should have created the commit without
    these paths.
 
+ * "git diff --stat" said "files", "insertions", and "deletions" even
+   when it is showing one "file", one "insertion" or one "deletion".
+
+ * The output from "git diff --stat" for two paths that have the same
+   amount of changes showed graph bars of different length due to the
+   way we handled rounding errors.
+
+ * "git grep" did not pay attention to -diff (hence -binary) attribute.
+
+ * The transport programs (fetch, push, clone)ignored --no-progress
+   and showed progress when sending their output to a terminal.
+
+ * Sometimes error status detected by a check in an earlier phase of
+   "git receive-pack" (the other end of "git push") was lost by later
+   checks, resulting in false indication of success.
+
+ * "git rev-list --verify" sometimes skipped verification depending on
+   the phase of the moon, which dates back to 1.7.8.x series.
+
  * Search box in "gitweb" did not accept non-ASCII characters correctly.
 
  * Search interface of "gitweb" did not show multiple matches in the same file
