The first paragraph of the NEWS file lists the following:

 * Release 0.7.6 (30 Sep 2007)
 
 ** Things You Need To Know
 
 *** 'buildbot upgrade-master'
 
 Each time you install a new version of Buildbot, you should run the new
 'buildbot upgrade-master' command on each of your pre-existing buildmasters.
 This will add files and fix (or at least detect) incompatibilities between
 your old config and the new code.

I'll see about changing the README and the buildbot.net front page to make
this file more prominent, as well as add some pointers in the user's manual.
In general, each time you install a new buildbot release, please read the top
of the NEWS file to find out what has been changed and how you need to deal
with those changes.

In this case, the 'buildbot upgrade-master' command will copy those
public_html/ files into your buildmaster directory, as well as informing you
about the c['bots'] and c['sources'] changes.

The NEWS file for 0.7.5 also described the buildbot.process.step ->
buildbot.steps change that Benoit mentioned.

In general, I'd recommend upgrading to the latest buildbot version one
release at a time. I make it a policy to provide deprecation warnings for
features that are to be removed for a few releases before actually removing
them, and upgrading partway first will give you a chance to see those
warnings and update your config to match.

Yeah, I think I'm going to try to release 0.7.7 in the beginning of December
to get this fix into a real release (as well as a few other really annoying
ones).
