+GIT v1.5.4.5 Release Notes
+==========================
+
+Fixes since v1.5.4.4
+--------------------
+
+ * "git fetch there" when the URL information came from the Cogito style
+   branches/there file did not update refs/heads/there (regression in
+   1.5.4).
+
+ * Bogus refspec configuration such as "remote.there.fetch = =" were not
+   detected as errors (regression in 1.5.4).
+
+ * You couldn't specify a custom editor whose path contains a whitespace
+   via GIT_EDITOR (and core.editor).
+
+ * The subdirectory filter to "git filter-branch" mishandled a history
+   where the subdirectory becomes empty and then later becomes non-empty.
+
+ * "git shortlog" gave an empty line if the original commit message was
+   malformed (e.g. a botched import from foreign SCM).  Now it finds the
+   first non-empty line and uses it for better information.
+
+ * When the user fails to give a revision parameter to "git svn", an error
+   from the Perl interpreter was issued because the script lacked proper
+   error checking.
+
+ * After "git rebase" stopped due to conflicts, if the user played with
+   "git reset" and friends, "git rebase --abort" failed to go back to the
+   correct commit.
+
+ * Additional work trees prepared with git-new-workdir (in contrib/) did
+   not share git-svn metadata directory .git/svn with the original.
+
+ * "git-merge-recursive" did not mark addition of the same path with
+   different filemodes correctly as a conflict.
+
+ * "gitweb" gave malformed URL when pathinfo stype paths are in use.
+
+ * "-n" stands for "--no-tags" again for "git fetch".
+
+ * "git format-patch" did not detect the need to add 8-bit MIME header
+   when the user used format.header configuration.
+
+ * "rev~" revision specifier used to mean "rev", which was inconsistent
+   with how "rev^" worked.  Now "rev~" is the same as "rev~1" (hence it
+   also is the same as "rev^1"), and "rev~0" is the same as "rev^0"
+   (i.e. it has to be a commit).
+
+ * "git quiltimport" did not grok empty lines, lines in "file -pNNN"
+   format to specify the prefix levels and lines with trailing comments.
+
+ * "git rebase -m" triggered pre-commit verification, which made
+   "rebase --continue" impossible.
+
+As usual, it also comes with many documentation fixes and clarifications.
