Changelog for v1.9

Enhancements

• The longpoll session token is now sent in a x-phoenix-longpoll-token header instead of the query string. If you do rolling deploys where both old and new nodes are active at the same time, ensure that you deploy Phoenix v1.8.10 or a later v1.8 release first.

v1.8

The CHANGELOG for v1.8 releases can be found in the v1.8 branch.
