Starting with version 0.8.0, Weaver no longer offers out-of-the-box support for other effect types than cats-effect.
We (maintainers) are happy to keep the core of weaver effect-agnostic, in an effort to allow for third party to resurrect support for the effect types they use in repository they control.
You can read about the rationale for decision here. Feel free to ping us via a github discussion, if you seek to resurrect support for a given effect-type.
If you are looking for documentation of the maintenance branch of weaver that did support other effect types, you can find it over there.
We will try to fix critical bugs on the 0.6/0.7 series, as they get found.
To summarise :
0.8.xand further -> CE3 only, active development,
0.7.x-> CE3 + ZIO 1 support (maintenance mode, fixing critical bugs that not have workarounds)
0.6.x-> CE2 + Monix/MonixBIO/ZIO 1 support (maintenance mode, fixing critical bugs that do not have workarounds)
