  * The date parser now accepts timezone designators that lack minutes
    part and also has a colon between "hh:mm".
 
+ * On some BSD systems, adding +s bit on directories is detrimental
+   (it is not necessary on BSD to begin with). The installation
+   procedure has been updated to take this into account.
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+   default value of the hostname part of the committer/author e-mail.
+
  * "git am" learned how to read from patches generated by Hg.
 
+ * "git archive" talking with a remote repository can report errors
+   from the remote side in a more informative way.
+
  * "git branch" learned an explicit --list option to ask for branches
    listed, optionally with a glob matching pattern to limit its output.

+ * "git grep" used to incorrectly pay attention to .gitignore files
+   scattered in the directory it was working in even when "--no-index"
+   option was used. It no longer does this. The "--exclude-standard"
+   option needs to be given to explicitly activate the ignore
+   mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+    searched in untracked (but not ignored) files as well as tracked
+    files in the working tree, so that matches in new but not yet
