See: https://github.com/composewell/streamly/pull/2872 Also, see: https://github.com/composewell/streamly/issues/2873

@locallycompact The master branch of streamly now builds with 9.12-alpha. See the 9.12-alpha CI.

[locallycompact]

Great! Thanks.

[adithyaov]

Reopening this issue to track the release of 0.10.2 This change will be a part of the 0.10.2 release.

[ysangkok]

streamly was just removed from Stackage because v0.10.1 isn't compatible with the boot libs of ghc 9.10:

        - streamly < 0 # tried streamly-0.10.1, but its *library* requires hashable >=1.3 && < 1.5 and the snapshot contains hashable-1.5.0.0
        - streamly < 0 # tried streamly-0.10.1, but its *library* requires template-haskell >=2.14 && < 2.22 and the snapshot contains template-haskell-2.22.0.0

[mchav]

Yeah. Also facing the template Haskell issue. As an aside when we'll 0.10 be pushed to package?

[adithyaov]

streamly-0.11.0 which will release shortly will be compatible with all ghc <= 9.12 I can however revise some constraints on hackage for streamly-0.10

[georgefst]

I can however revise some constraints on hackage for streamly-0.10

That would be great. I've just had to add allow-newer: streamly:template-haskell, streamly-core:template-haskell to get Streamly to build with GHC 9.10.1.

[harendra-kumar]

streamly on hackage now supports ghc 9.10 and 9.12 .
