@stevenfontanella Ping?

@stevenfontanella Would really appreciate a Hacakge metadata edit as well

[stevenfontanella]

Yes, will create a release later tonight.

Unless you have other changes that warrant a release, the only changes in this PR are to dependency upper bounds and they can be fixed with metadata update. I am a Hackage Trustee and I can even do them for you if you would like,

Released:

• microlens-platform-0.4.3.6
• microlens-th-0.4.3.16
• microlens-pro-0.2.0.2

Re: a metadata-only update for this change: so far I prefer patch releases for changes like this. I feel that it's better since it removes the time element, e.g. if we didn't make a patch release here, the question "does microlens-pro 0.2.0.1 support GHC 9.12?" doesn't have a clear answer; it depends on when that library was installed. Is there any downside to making a patch release in this case instead of a metadata-only update? If it's not a common practice among other libraries, I can just adopt the more common practice too.
