Problem

We want to release the next versions of our Twitter OSS util 19.8.1

Solution

Prepare util for their next releases.

Result

We will need to temporarily upgrade all versions for passing build.
But we will only publish util 19.8.1.
post-release will reset all versions back to 19.9.0-SNAPSHOT.
