• Installation:

  julia -e 'using Pkg; Pkg.Apps.add(; url="https://github.com/aviatesk/JETLS.jl", rev="2026-03-19")'

Added

• Added @main function support across LSP features (document-symbol, document-highlight, references, rename, completions, diagnostic).

• Added lowering/unused-assignment diagnostic that detects assignments whose values are never read (dead stores).
  This complements the existing lowering/unused-local diagnostic: lowering/unused-local reports variables that are never used at all, while lowering/unused-assignment reports specific assignments to variables that are used elsewhere.
  For example:

  function f(x::Bool)
      if x
          z = "Hi"
          println(z)  # z is used, so no `unused-local`
      end
      if x
          z = "Hey"   # but this value is never read → `unused-assignment`
      end
  end

Changed

• lowering/undef-local-var now reports a diagnostic for each use site on an undef path individually, rather than only reporting the first one.
• lowering/undef-local-var @isdefined propagation now recognizes @isdefined(var) within && chains (e.g., if cond && @isdefined(y)), suppressing false positive diagnostics in the guarded branch.
• Updated JuliaSyntax.jl and JuliaLowering.jl dependency versions to latest

Fixed

• Fixed false positive lowering/unused-binding warning for keyword arguments that are only used in computing other keyword arguments' default values (Closed #592).
• Fixed false positive lowering/unused-import warning for imports used inside quoted expressions in macro bodies or helper functions (Closed #594).
• Fixed lowering/undef-local-var diagnostic being reported at the wrong location:
  when a variable had both defined and potentially-undefined uses, the diagnostic pointed to the first use in source order rather than the use that is actually on the undef path.
• Fixed signature-help error when displaying signatures for operator-like methods (e.g. Base.:(==)).
• Fixed "Delete assignment" code action removing the opening delimiter of string literals (e.g., z = "Hey" became Hey" instead of "Hey").
