AttributeError: 'Tag' object has no attribute '_slug'

I'm playing with the master (8786732) a bit but I get this:

WARNING: Caught exception "'Tag' object has no attribute '_slug'". Reloading.

can you provide more info that might be relevant? configs/content/etc. you know the drill.

Ooops, I thought it was some known-ish issue. Turns out I had cache on and the old cache unpickled incompatible stuff.

Worth documenting in the next release notes I suppose?

[ionelmc]

Or maybe have a "version" attribute/field/something in the cache files?

PS. I have CONTENT_CACHING_LAYER = 'reader' in the settings

Documented this in the upgrade notes at the bottom of the release announcement.
