It's basically bug fixes. It's somewhere on the road between x.y.z and
x.y.z+1 so glancing at the NEWS file might give you an idea of what
typically gets changed. The policy is quite conservative, bug fixes go
in if considered safe, but we do allow adding "obviously missing"
functionality to be added, and also some development in areas that
have been labeled "experimental". Of course, since they are not actual
releases, there is always some risk of a bad fix or catching the
repository in a half-updated state.
