Dear development community,

I am happy to start the VOTE thread for a Groovy $relVersion release!

This release includes $fixCount bug fixes/improvements as outlined in the changelog:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=$projectId&version=$versionId

Tag: $repoBase?p=groovy.git;a=tag;h=refs/tags/GROOVY_$underVersion
Tag commit id: $tagId

The artifacts to be voted on are located as follows (r$svnVersion.maxRevisionNumber).
Source release: https://dist.apache.org/repos/dist/dev/groovy/$relVersion/sources
Convenience binaries: https://dist.apache.org/repos/dist/dev/groovy/$relVersion/distribution

Release artifacts are signed with a key from the following file:
https://dist.apache.org/repos/dist/release/groovy/KEYS

Please vote on releasing this package as Apache Groovy $relVersion.

Reminder on ASF release approval requirements for PMC members:
http://www.apache.org/legal/release-policy.html#release-approval
Hints on validating checksums/signatures (but replace md5sum with sha256sum):
https://www.apache.org/info/verification.html

The vote is open for the next 72 hours and passes if a majority of at least three +1 PMC votes are cast.

[ ] +1 Release Apache Groovy $relVersion
[ ]  0 I don't have a strong opinion about this, but I assume it's ok
[ ] -1 Do not release Apache Groovy $relVersion because...

Here is my vote:

+1 (binding)
