[v0.8.4] - 2021-03-29

We’re getting there, conda packages work again… However, I forgot to delete an assert statemente introduced for debugging ¯_(ツ)_/¯

All of v0.8.1 - v0.8.4 are very minor fixes on top of [v0.8.0] - 2021-03-19; read those release notes.

As a fix, this version also changes a default parameter: SingleSiteDMRG now uses a mixer by default.
