blocked by simulacrum at the moment, but there's probably other things too (catalysts?)

[SethTisue]

note that kind-projector moved from org.spire-math to org.typelevel in their version 0.10.0 release

[SethTisue]

simulacrum has now published. not sure what the next blocker is

[SethTisue]

I submitted some WIP at #2783 that I don't intend to finish myself

[SethTisue]

catalysts, I think

[SethTisue]

#2791 and #2792 are both merged. is there more work to do before publishing levers can be pulled...?

[kailuowang]

@SethTisue I am waiting on a discipline maintainer releasing a milestone with this PR merged in typelevel/discipline#89

[SethTisue]

@kailuowang I see, would that be @larsrh ?

[larsrh]

0.11.2-M1 is on its way to Maven Central

[kailuowang]

Last PR (i hope) #2806 before 2.0-M1 release on 2.13-RC1

[djspiewak]

@kailuowang Are you going to do a cross-build in the 1.x line on 2.13?

[kailuowang]

@djspiewak we don't plan to release any non-bug-fix releases in the 1.x line. Cats 2.0 is binary compatible with 1.x on cats-core and cats-free.
The only major breaking changes Cats 2.0 introduces is upgrading to Scalatest 3.1.0 and Scalacheck 1.14.0. (There are a couple of minor breaking changes in cats-laws and alleycats, but they are unlikely to impact use site)
These dependency upgrades are intertwined with the update to support Scala 2.13-RC1. For example, Scalacheck 1.13 does not support scala 2.13, and Scalatest 3.0.x does not support Scalacheck 1.14, so if you don't want to upgrade those two, it's not obvious how you can support Scala 2.13 unless you chose to use different scalatest and scalacheck versions for Scala 2.13 and Scala 2.12 (which is what cats has been doing up to this point, with the new API changes in Scalatest 3.10 it's not obvious how to continue to do that. )

[djspiewak]

That's all very reasonable. I was mostly thinking about what I wanted to do with shims.
