@snuyanzin 36334 is ready. I patched previous releases just to generate proper test files. Now the test runs just fine. Next I will generate test files for release-2.3 and change most_recently_published_version to v2_3

Next I will generate test files for release-2.3 and change most_recently_published_version to v2_3
