Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A solid GUI Framework for Haskell?
Why do you need a GUI library, if you can write your application using extensible effects frameworks, just choose any and enjoy!

An alternative front end for Haskell?
> I think Haskell needs a way to graduate (or retire) language extensions
-
Or patterns proposal: Prefix signalling or just infix?
Additionally, while this proposal is focused on the simple implementation and so in the current proposal or patterns do not bind any variables as per #522, if we do get settled on syntax and then later wish to expand to allow binding variables as in #43, then the syntax is again clean and discoverable.

Amendmend proposal: Changed syntax for Or patterns
as syntax is contentious a topic as ever, David (the main proposal author) and I would like to invite you to give your input on https://github.com/ghc-proposals/ghc-proposals/pull/585, where we propose to change the syntax of the accepted proposal #522 introducing Or patterns. In particular, we'd like to know

{-# WARNING #-} for Data.List.{head,tail} in future GHC 9.8
It's coming: https://github.com/ghc-proposals/ghc-proposals/pull/541
Right. Being able to disable "custom type warnings" at use sites was part of an earlier proposal (https://github.com/ghc-proposals/ghc-proposals/pull/454) but it ended up being shelved.

High-Performance Haskell?
The lack of concatMap fusion is a notorious issue in stream fusion. I recently implemented Higher Order Patterns in Rewrite Rules which should make it possible to write a rewrite rule for fusing concatMap in GHC 9.8.

The Haskell Playground supports GHC 9.6 alpha 2! You can now preview features like the error codes and the TypeData extension!
The initial proposal was data kind, but in the discussion some people didn't like the word "kind".

How does your programming language implement multi-line strings?
I learned about this when proposing multiline strings in Haskell. The convo there might be of interest to you: https://github.com/ghc-proposals/ghc-proposals/pull/569
