AFAUI, 0.5 introduced, among others, the fact that libs are not loaded 
by default unless explicitly requested:

https://github.com/zarch/grass-session/commit/b1d4c0fa574bdbd86716fb504ce05e8b449a9dfc#diff-6f5e014607121aae5fa1a45459276b57eceb9194cc53dd65413d973faf59dd87

I'm not 100% sure I understand how it works, but IIUC, you should be 
able to something like this (untested):

Session(gisdb="/tmp", location="location", create_opts="EPSG:4326", 
loadlibs=True)

Don't know what the rationale behind this change is, though.
