gRPC Java 1.4.0

[Carl Mastrangelo]

gRPC Java is now released (and should show up on Maven Central within a few hours)

Changes:

API Changes

• LoadBalancers can now update addresses for a channel in-place, allowing the channel to re-use existing connections
• The previously deprecated affinity API is now deleted. (#3026)

Bug fixes

• Overly large messages now return RESOURCE_EXHAUSTED (#2906)
• Netty-tcnative load failures may now be detected earlier and cause an exception during build()instead of creating a hung channel (#2599)
• OkHttp now ignores unknown SETTINGS (#3032). This resolves an important incompatibility with C-wrapped language instances of gRPC
• Fixed dependency specification to avoid wildcards, which are not universally supported (#2961)
• Channel.authority() should return the value of overrideAuthority (#2682)

Other

• gRPC now does TXT record lookups for implementing service config. Android users will need to add proguard configs to ignore javax.naming.** classes (#2912)
• Protobuf bumped to 3.3.0
• Disconnect messages have been silenced as non errors (#2960)
• Netty has been upgraded to 4.1.11 and Netty TC Native 2.0.1
• More work to support HTTP GET method. This work is considered experimental and known to have future incompatible wire changes
• Fixed support for the AppEngine development sandbox
