===============================
Larger than the usual "patch" release because it's been so long since the last
version and a number of bugs crept in. New maintainer (dgw) says hi.
To reduce the "dependency hell" of installing things that Sopel doesn't need
unless specific modules are used, the `spellcheck` and `ipython` modules will
likely be removed from core and published separately in a future release
(tentatively, Sopel 7).
----
