2.12.0 changelog (#1038)

* Merge pre-release sections

An odd bug (or user error?!) with readthedocs leads
to all pre-release anchors in the changelog to be
reduced to just the final component (e.g. "a2").
Rather than struggle with this, this proposes to use
the official anchor for the upcoming release, but to
clearly mark it as a pre-release.

* Fix minor warning from the sphinx parsing

* Update to the new logo

* Drop purple from the sidebar

* Fix typo in release.rst comment

* Drop pre-release warning
