Looks like integration tests are failing, not sure if it's related, take a look?

Also, to use this code, will have to create a release. When will be releasing this?

@dblock Can you also merge the PR, I'm not able to merge it.

I'm retrying to specs, we need a passing build. There's an issue open for it, #568, if you/someone/anyone wants to take a look that would be helpful. Will merge when/if it passes.

Also, to use this code, will have to create a release. When will be releasing this?

Open an issue to release v. Next if you need it quickly, one of the maintainers can cut it fairly easily.

@17sushmita https://github.com/opensearch-project/opensearch-go/actions/runs/13259031094/job/37011215963?pr=663 has failed repeatedly. I think JDK needs to be bumped to 21 in https://github.com/opensearch-project/opensearch-go/blob/main/.github/workflows/test-integration-unreleased.yml#L14. Can you please take a look?

[17sushmita]

yes, java version was the issue, updated it to 21. All tests are passing now.

Open an issue to release v. Next if you need it quickly, one of the maintainers can cut it fairly easily.

[17sushmita]

I've raised an issue to create release - #666
