If it was a patch upgrade (that is, only the right-hand-most digit changed: 0.6.0 -> 0.6.1), then you should be safe from broken plugins, as all changes are backwards compatible.
The real fun stuff happens when we go from 0.6.x to 0.7.x 👿
Edit: I jest. 0.5.x to 0.6.x was harder than we expected, since we changed the static:app.init hook, which practically every plugin uses.
0.7.x has comparatively fewer breaking changes, but it is a long way out yet... :shipit:
