For this release we completely refactored low-level implementation of http handling.
Finally uvloop gives performance improvement. Overall performance improvement
should be around 70-90% compared to 1.x version.

We took opportunity to refactor long standing api design problems across whole package.
Client exceptions handling has been cleaned up and now much more straight forward. Client payload
management simplified and allows to extend with any custom type. Client connection pool
implementation has been redesigned as well, now there is no need for actively releasing response objects,
aiohttp handles connection release automatically.

Another major change, we moved aiohttp development to public organization https://github.com/aio-libs

With this amount of api changes we had to make backward incompatible changes. Please check this migration document http://aiohttp.readthedocs.io/en/latest/migration.html

Please report problems or annoyance with with api to https://github.com/aio-libs/aiohttp
