BitShares Testnet test-6.1.1 was released today, mainly with fixes to the Elastic Search plugins.
More info (release notes, binaries, docker and etc) is on the release page.
Testnet nodes running version test-6.1.0 with the elasticsearch plugin or the es_objects plugin enabled need to be upgraded. Other Testnet nodes are recommended to be upgraded, although not required.
Awesome! Great work :)
