This release contains performance improvements for compressed hypertables
and continuous aggregates and bug fixes since the 2.11.2 release.
We recommend that you upgrade at the next available opportunity.

This release moves all internal functions from the _timescaleb_internal
schema into the _timescaledb_functions schema. This separates code from
internal data objects and improves security by allowing more restrictive
permissions for the code schema. If you are calling any of those internal
functions you should adjust your code as soon as possible. This version
also includes a compatibility layer that allows calling them in the old
location but that layer will be removed in 2.14.0.

I don't see #6067 included - the updates required for Data Tiering GA is a major reason why we are having 2.12 a little bit earlier, so we should make sure that everything is included before tagging.

@svenklemm do you mind also making sure with @zilder, @gayyappan that this is the only one remaining and that there is nothing else we forgot to add to the 2.12 milestone?

#6067 has not been merged yet, will add it once its merged.

Shouldn't we include PG12 deprecation? @iroussos, what would be a good one-liner for the release notes?
