Last week develop was successfully migrated from publishing -SNAPSHOT to publishing -build.nnn, as discussed on the dev list.
I propose that we bring the same change to support/1.13 and support/1.12 for consistency. This will allow downstream projects to change over the new model “everywhere" rather than having to maintain support for both ways and constantly try to remember which branches do it which way. The specific changes to be cherry-picked from develop are a4c8b <https://github.com/apache/geode/commit/a4c8b9ed8bbea584f798164fa5308d236e9b6048> and 39c52 <https://github.com/apache/geode/commit/39c522e340196cb30d55d81d93c63028938cd782>. I have prepared PR #5089 <https://github.com/apache/geode/pull/5089> for support/1.13 and PR #5090 <https://github.com/apache/geode/pull/5089> for support/1.12 due to the version number differences on each branch.
