The UTF-8 character set encoding is the industry standard. Haskell Foundation is driving the effort behind the migration of the core text libraries to use UTF-8 as a default. This will have a positive effect on text performance of many Haskell programs.
Building a universal installer for Haskell toolchains. This effort brings together the Stack and GHCup teams to help build a single installer that will allow HLS, Cabal, Stack, and GHC installations on all major platforms from a single tool.
The Haskell Foundation is working with the GHC team to provide a better build experience for GHC, allowing them to iterate quicker, fix bugs faster, and make our tools better.
A common framework for linking Haskell maintainers to prospective contributors
A community-led book-writing effort that captures the general wisdom for how to make Haskell programs go fast.
A proposal for providing a common fusion framework and underlying primitives for stringy data structures in base.
The Haskell Foundation is working with the GHC team to help provide dashboard monitors for Haskell critical libraries (e.g. Aeson, Text, Bytestring)
