Currently, we only added the jassert to the master branch. I was wondering whether we could backport the corresponding PR [1] to release-1.14 and release-1.13, too. Otherwise, we would have to implement tests twice when providing PRs with new tests that need to be backported: The jassert version for master and a hamcrest (or any other available library) for the backports.
It's not really a bugfix. But it might help developers with their backports.
