Changelog

26.0.1 (2026-04-13)

Bugfixes

• Suppress downstream type mismatch diagnostics when the underlying type is already invalid. This reduces cascading error noise and makes compiler output easier to read. (#1386)
• Fix chained method call type inference (e.g. result.map(fn1).map(fn2)). The compiler now correctly unifies types through canonicalized receivers, resolving incorrect type mismatch errors on valid method chains. (#1389)
• Overhaul LSP stability and observability: worker-thread panics now surface as visible errors instead of being silently swallowed, a dual-layer logging system writes detailed diagnostics to workspace-local .fe-lsp/ log files with automatic rotation and retention, and a dispatch-deadlock in concurrent request handling has been fixed via an upgraded async-lsp dependency. (#1392)
