* Tell the user which packages are queued for update or checkout, so one can
check which packages are still updating now that the output is only printed
after everything is done due to parallel checkouts.
[fschulze]
* Added ``always-accept-server-certificate`` option. When set in the
``[buildout]`` section, then invalid certificates are always accepted for
subversion repositories.
[fschulze]
* Added ``-v``/``--version`` option.
[tomster, fschulze]
