Changes in v0.10.2: We merged the "context_middlewares" branches with commit ceaf6a52. The goals of this branch are:

• No work-a-round in template inheritance needed for context middlewares (issues 13)
• optimized render process (issues 51)

This is not "backward incompatible", but the work-a-round described in issues 13 is obsolete, you can remove it if you have used it.
