Hey Folks,

The Grizzly Team is happy to announce the release of grizzly-http-client
1.9[1] !
We decided to bump the async-http-client [1] dependency branch to 1.9.x
(previously it was 1.8.x), so some minor API incompatibilities could be
observed.
 From now on async-http-client 1.8.x based releases of
grizzly-http-client will be numbered: 1.8.1, 1.8.2 ... and
async-http-client 1.9.x based releases will be numbered 1.9.1, 1.9.2...
so it will be easier to map grizzly-http-client to async-http-client
branches.

Thanks!
  - The Grizzly Team
