0.5.1

  • Upgraded dropwizard metrics to 4.0.2

0.5.0

  • Upgrade to Netty 4

NOTES:

  • See Netty 4 upgrade notes

  • As mentioned Netty 4 won't flush sends automatically. By default this client will flush after each message, this can be controlled via the autoFlush field on the Transports.

  • Resolver class was removed. Netty will resolve on each new channel when the supplied address is created via InetSocketAddress.createUnresolved.

  • use of HashedWheelTimer has been replaced by the Executor provided by the ChannelHandlerContext

  • Previous versions used to explicitly disable SSL TLS renegotiation. This no longer appears to be part of Netty. Stack Overflow suggests setting the JDK8+ System Property jdk.tls.rejectClientInitiatedRenegotiation

  • Use individual Netty Jars rather than netty-all. Use of netty-all can hinder dependency resolution when different projects use Netty on the same classpath. See example from Aleph

  • Remove ChannelGroupHandler the Transport connect add the channel at each connection attempt. The Netty Channels class automatically removes channels as they close.

  • Enable metrics reports to include state values based on the values of the metrics. This adds support for computation and reporting of metric states. The implementation associates ranges of values with user-defined states, defaulting to ok if no filters have been set up or none of the associated filters applies.
