v3.0 release

[cb372]

This issue is to track work towards a v3.0 release of cats-retry.

I'd like to see:

• upgrade to cats-effect 3 (and will there be a cats-core 3?)
• cross-build for Scala 3 (and drop 2.12?)
• isWorthRetrying (and other A -> Bool functions) should allow for effects (A -> M[Bool]) #283 (make all predicates effectful)

Nice to have:

• port the tests from scalatest to MUnit - I get the impression this would make life easier when cross-building for Scala 3, but I don't have any hard facts to back that up

Any other breaking changes people want to suggest, now's your chance. Bring out your dead!

Opened a WIP PR #291
Tackles the updates and fixes to Scala 3.0 and CE-3.0. Nothing about #283 or the mdoc examples for the moment.

A release supporting Scala 3 and CE2 would also be very useful.

Just remembered we have some deprecated methods in the API (e.g. retryingM). Let's delete those before v3.0.

v3.0.0 was released! It includes the upgrade to CE3 but not cross-building for Scala 3. We didn't delete those deprecated methods, but never mind.

I'll close this issue.

We still need to cross-build for Scala 3. We have a couple of PRs we can use as a reference for that:

• Add support for Scala 3 #294 - switching tests to munit and cross-building for Scala 3, on the series/2.x branch
• WIP#287 Upgrade CE&Scala v3.0. Switch to munit #291 - switching to munit, cross-building for Scala 3, and upgrading to CE3 (that part was superseded by "migrate" to cats effect 3  #305)
