2.6.0

• [FIXED/ADDED] - #197 - the ability to use a single dispatcher for multiple message handlers, including multiple subscriptions on a single subject
• [FIXED] - #252 - deprecated strings for username/pass/token and use char arrays instead, required changing some other code to CharBuffer
• [FIXED] - #255 - added special ioexception when possible to indicate an authentication problem on connect
• [FIXED] - cleaned up use of "chain" instead of "creds"
• [ADDED] - Openjdk11 to travis build and updated gradle wrapper to 5.5
• [ADDED] - an option to trace connect timing, including a test and example

2.5.2

• [FIXED] - #244 - fixed a critical issue with parsing ipv6 addresses in the info JSON, added unit test for parser
• [FIXED] - #245 - fixed a timing bug in nats bench, now subscribers start timing at the first receive
• [FIXED/CHANGED] - #246 - fixed a confusing output from nats bench in CSV mode, now the test count and the total count are printed
• [ADDED] - spring cache to git ignore file
• [ADDED] - support for running nats bench with conscrypt

2.5.1

This release was motivated by some TLS performance results. The primary change is #241 which allows several native libraries to be used if preferred over the j2se SSL implementations.

• [FIXED] - #239 - cleaned up extra code after SSL connect failure
• [FIXED] - #240 - removed stack trace that was left from debugging
• [FIXED] - #241 - changed method used to create an ssl socket to allow support for conscrypt/wildfly native libraries
• [ADDED] - conscrypt flag to natsautobench to allow testing with native library, requires Jar in class path

2.5

2.5 introduces a new implementation of the underlying message queue used by subscribers, dispatchers and the publish code to hold messages. The new implementation allows the publish side to provide some backpressure when the network is not as fast as the application.

This new version may change performance characteristics of publishers but should show better overall performance across req/reply and pub/sub scenarios.

Latency should be un-changed.
