  What I was hit with were subtle changes to how [[ ]] worked, along the lines of implicit anchoring in pattern in previous version not taking place in succeeding version. It took quite a while to debug what became a logic error. After that I started avoiding bashisms in my scripts, especially that they usually provide very little benefit at the cost of gambling against breaking silently on a barely related update. Nowadays it's also worth noting that #!/bin/sh often (Debian derivatives) points to something that is not Bash, and people writing in shell/Bash usually don't understand the difference.
