Erlang Solutions packages release schedule

We are using Erlang Solutions custom packages for installation of elixir / erlang on our Ubuntu servers. They are great, however we have some issues with irregular release schedule - e.g. latest elixir version is currently 1.12.2, latest Erlang Solutions package is 1.12.0.

Releases being somewhat late is not our main issue, it is that we could not find any predictable release schedule for Erlang Solutions packages. Is there a general rule / info available on when (and IF) new releases of Elixir will be available in Erlang Solutions repository?
