------------------ - Make listify_headers UTF-8 encode keys (bugfix see issue 55).
4.2.1
------------------ - Make HTTPTimeoutError inherit from crochet.TimeoutError. This helps with code that still catches crochet.TimeoutError and also helps with a recent change in bravado to convert crochet.TimeoutError into HTTPTimeoutError.
4.2.0
------------------ - Move TLS support into an extras so that the vast majority of users that are not using TLS don't need to install extra dependencies. If you do use TLS/SSL please make sure you're installing (or depending on) fido[tls].
4.1.0
--------------------- - Drop support for Python 2.6, fixing a build failure due to attrs not being Python 2.6 compatible anymore.
4.0.1
--------------------- - Throw HTTPTimeoutError only if it was caused by CancelledError (bugfix).
4.0.0
--------------------- - Refactoring exceptions to distinguish between Connection errors and HTTP request/response errors.
