This Week's Rails Contributors

This week 29 code athletes contributed to Rails. We also got 1 first time contributor. Welcome aboard the Rails Games!

Allow specifying encoding of parameters by action

Controllers can list the parameters with parameter_encoding, providing the action and the encoding type.

thread_mattr_accessor was sharing the variable with superclasses and subclasses. Setting the variable in one would compromise the other.

Fix the Accept header overwritten issue in integration tests

XHR integration tests were overwriting the Accept header and creating inconsistency with HTTP_ACCEPT.

Better logging of cached partial renders
