What is the process for determining when to release the next in the 4.2 series (4.2.8)? Is there a generally expected timeframe between releases? Or is it waiting on specific fixes?
For a release there needs to be need. I.e. we won’t just release the same code over and over, there needs to be meaningful patches. It also takes coordination and human power. Releasing is a non-trivial task. You can always use
github: 'rails/rails', branch: '4.2' in your gemfile if you need more recent than whatever is currently released. If there is a HUGE patch that has been in master that you really really want then you need to help raise awareness. You could reply to the commit or PR where the patch was introduced, you could post on this list.
