There are eight releases across four release series in the past 12 months and a milestone release (9.6.7) is cut by an external employer, showing the release infrastructure works for distributed teams. Language work lands: binding type variables and visible foralls, linear types with lead bindings, and instance deprecation. Tooling and backends advance: JavaScript FFI for WASM, RISC‑V and SIMD work, ARM64 Windows support, improved GHCI debugger and browser GHCI, compressed info tables and exception annotations with annotateIO for usable backtraces. Infrastructure migrates off Equinix to DigitalOcean/OpenCape; ARM64 CI hardware remains an open need.
