@reidrac@social.sdf.org I've updated my stuff to 9.4 (the LTS), but we run 9.6 at work and it is visibly better. Faster at compiling, nicer profiling tools, etc.
If your dependencies are 9.6-reafy, then go for it.
No reason to stick with older GHCs unless there's some huge blocker (like the 9.0 had).
@reidrac@social.sdf.org I use my "done" projects as testbeds and always updating them to match latest engine version.
But finished games may stick to their LTSs until the end of times.
