 ==================
 
 - `meta-recipe support`_
 
 - `Conditional sections`_
 
+- Buildout now accepts a ``--version`` command-line option to print
+  its version.
+
+Fixed: Builout didn't exit with a non-zero exit status if there was a
+       failure in combination with an upgrade.
+
+Fixed: We now fail with an informative error when an old bootstrap
+       script causes buildout 2 to be used with setuptools.
+
+Fixed: An error incorrectly suggested that buildout 2 implemented all
+       of the functionality of dumppickedversions.
+
+Fixed: Buildout generated bad scripts when no eggs needed to be added
+       to ``sys.path``.
+
+Fixed: Buildout didn't honour Unix umask when generating scripts.

+Fixed: ``update-versions-file`` didn't work unless
+       ``show-picked-versions`` was also set.
