[RELEASE] DataStax Java driver 2.0.10.1 and 2.1.6

[Olivier Michallat]

We've just released two new versions of the driver:

2.0.10.1 is a patch release for the 2.0 branch. Its primary goal is to fix JAVA-768, a potential race condition in the connection pool code (this is a proactive fix: the chance of racing is extremely low and we've not been able to make it happen in practice).

We've also used this opportunity to fix a few other tickets:

- the driver now uses Netty's pooled ByteBuf allocator by default

- the paging state API now comes in a "unsafe" version, that doesn't check the statement when reinjecting the state (read the online doc for further details).

2.1.6 is an update on the 2.1 branch with all the recent 2.0 changes.

Please refer to the online documentation for more:

- 2.0.10.1: http://datastax.github.io/java-driver/2.0.10.1/

- 2.1.6: http://datastax.github.io/java-driver/

The new versions have been pushed to the central Maven repository. Binary distributions will be published shortly to http://downloads.datastax.com/java-driver/
