Oscar patch releases 3.0.2 and 2.1.1 released

[solari...@gmail.com]

Hi everyone,

We've released Oscar versions 3.0.2 and 2.1.1 today, both of which are patch releases to fix a version incompatibility with one of Oscar's dependencies (django-treebeard).

django-treebeard is pinned to version 4.4.x, because version 4.5 introduces a breaking change that requires database migrations.

Cheers,

Samir
