The 3.0 release mostly only affects distribution maintainers as
the build and packaging details change in support of shared libraries
and dynamically loadable maps. Otherwise, user-visible changes are
minor, and backwards incompatible changes are subject to the
"compatibility_level" setting. See the release notes.
Therefore, I would not suggest stopping at 2.11, but only you can
determine whether some changes in a later release are unexpectedly
a problem for you. As much as possible, Postfix remains backwards
compatible.
