v0.31.0: 9 June 2026

Highlights

  • Added support for Elixir 1.20 (and OTP 29 on 1.20)

Improvements

  • Completion subsystem ported wholesale onto the 1.20 engine with more accurate block keyword (do, else, rescue, catch, after, end) completions
  • Go to definition now resolves functions and macros defined inside __using__ macros Paweł Świątkowski
  • Added OTP 28 nominal types support
  • Code.ensure_compiled calls eradicated from the codebase and from elixir_sense module store building, reducing compilation-related hangs and improving startup performance Steve Cohen
  • Ecto query completion now includes bindings from join associations
  • required is preserved in typespec suggestions

Fixes

  • Fixed call hierarchy ranges for calls in the current file
  • Match arity when naming call hierarchy items
  • Parse Erlang module names in call hierarchy
  • Only rewrite the diagnostic module's call in the "replace remote function" code action
  • Fixed struct field completion in record update syntax
  • Fixed keyword option completion text edit position
  • Guard against unknown association in Ecto query completion
  • Pass binding to scope resolution for route action completion
  • Do not get stuck when build is skipped on cwd change
  • Do not transfer nil PLT after failed dialyzer analysis
  • Fixed whitespace regex in function_def_on_line?
  • Do not treat # inside literals as a trailing comment
  • Fixed path_in_dir? for filesystem root
  • Handle error responses to server-initiated requests
  • Fixed mise shell detection when using nushell Bryan Iotti
  • Debug adapter: fixed off-by-one in hit count breakpoints
  • Debug adapter: plain breakpoints no longer consume conditional breakpoint slots
  • Debug adapter: fixed breakpoint condition unregister on removal
  • Debug adapter: fixed off-by-one in stackTrace levels paging
  • Debug adapter: fixed inverted singleThread handling in continue/step
  • MCP: fixed invalid response to the initialized notification
  • MCP: fixed location key for file:line:column in get_environment
  • Do not overwrite target dir on release

Breaking changes

  • Elixir 1.15 reached end of life and is no longer supported. Consider updating to 1.16+
  • OTP versions below 26 are no longer supported. Consider updating to OTP 26+
  • Legacy dialyzer support dropped — OTP's incremental Dialyzer is now the only engine, so the elixirLS.incrementalDialyzer setting has been removed
