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.

Haskell adoption is higher than I expected, what can we do to get it to top 10 languages.
Don't get me wrong, we figured it all out, and currently we use Aeson fork as we needed this: https://github.com/haskell/aeson/pull/926, as the default behaviour didn't work with Swift, and I wasn't sure if it's worth spending any time completing it...

How would aeson redesign FromJSON without intermediate Value?
Simdjson-based Hermes is able to decode JSON significantly faster while still using an intermediate representation: https://github.com/haskell/aeson/pull/923

The aeson vulnerability has been fixed in aeson-2.0.1.0
Ah, I see you are working on this already, thank you: https://github.com/haskell/aeson/pull/883

Text Maintainers: text-utf8 migration discussion - Haskell Foundation
Similar scan is already in aeson https://github.com/haskell/aeson/blob/master/src/Data/Aeson/Parser/Internal.hs#L322-L335 where the unsafeDecodeASCII is used I mentioned in my previous comment.

High-performance JSON codec
I'd be curious to see the benchmarks with the cffi flag enabled. aeson by default uses Haskell instead of C and this results in a pretty massive slowdown - the benchmark in that PR shows FFI being 12x faster.
Well, the aeson’s ffi code is written by me: https://github.com/haskell/aeson/commit/2f24e555d86a36fdda6d4cad79976004b382ab3b

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
