New: Julia for JetBrains IDEs (Flexible Julia)

Tooling
93

New Release: Flexible Julia 2026.3.2

New Features:

  • Remote Session Persistence: REPL sessions now survive disconnects via tmux/screen integration
    • New “Session manager” dropdown in SSH profile settings (None/tmux/screen)
    • Resume sessions from any IDE instance
  • JET.jl Documentation: Added tooltip explaining concretization_patterns limitations in LSP settings
  • New REPL IPC: Switched to backchannel communication (cleaner output, no more debug noise)
  • Plot Improvements: Better re-rendering support and titles now show in preview

Fixes:

  • Struct method completion now works inside functions (function f(x::MyType) → x. suggests methods)
  • ProxyJump SSH config alias resolution with underscores (my_server now resolves correctly)
  • Windows REPL prompt display when switching modes (julia>, pkg>, help>) - CRLF handling was causing corruption
  • Debug markers (__VAR__, etc.) no longer visible during exit()

If you’re running Julia on a remote server, your REPL session should now survive disconnects - just select tmux or screen in your SSH profile settings and pick up where you left off from any IDE instance.

There is also various improvements to our prompt window, now properly falling back to the original implementation for complex charts and various improvements in our own renderer.

Also finally squashed that Windows REPL prompt bug - mode switching should look clean now.

@xgdgsc: Thank you for the detailed reports on SSH, struct completion, and debug markers!

@ufechner7: Thanks for the REPL and JET.jl issue reports!

@PetrKryslUCSD: Appreciate catching that Windows prompt issue!
