Very cool to hear about your integration, I’m aware of the Windows issue and will address it. Thanks for your work on this!

New Release: Flexible Julia 2026.9.58

New Features:

  • Interactive Plots: Optional interactive view for Plots.jl with cursors, stats overlay, overview strip, log axes, and CSV export
  • Data Visualization: Data tab now plots columns and histograms directly in the Plots tab
  • Column Statistics: Data tab shows mean, std, quantiles, outliers, and a histogram sparkline per column

I am working on some improvements to the plot visualization. I added a new interactive plot view that makes it much easier to explore your data without leaving the IDE. Cursors, stats, and CSV export mean you can actually analyze what you are looking at instead of just staring at it. My hope is that over time we are improving on the plots view and making it more interactive/useful for all. To access the interactive mode click on the icon in the ribbon above the plot (note: not all plots supported).

Apart from that, I also added some stats to the data tab.

You might want to have a look at this notebook where I checked if you can edit attributes pseudo-interactively.

Doesn’t currently work with layouts though

Interesting. will take a look

Small bugfix release for Pluto notebooks. Hidden cells, @bind widgets, and notebook-local packages now work as expected.

@BeastyBlacksmith: Thank you for the Plots.jl attributes notebook and the bug reports!

New Release: Flexible Julia 2026.9.60

Fixes:

  • Environment pickers now list Project.toml folders from every folder open in the IDE, not only the first
  • When the language server does not start, the balloon now offers a one-click fix (install or reinstall JETLS, LanguageServer.jl, or Fatou, or open the Julia settings)

Small bugfix release. Multi-folder projects now work properly with the environment picker, and language server issues are easier to diagnose and fix.

@franckgaga: Thank you for the bug report!

New Release: Flexible Julia 2026.9.61

Features:

  • New “Unreachable code” inspection: code after return, break, continue, throw, or error is now grayed out, with a quick-fix to remove it

Small feature release. The editor now marks code that can never run, also after an if where every branch returns. Code that @goto can still reach is not marked.

New Release: Flexible Julia 2026.9.63

Fixes:

  • Codex CLI chat follow-up prompts no longer fail with exit code 2
  • Codex CLI chat uses the model from its own config by default
  • Codex CLI chat errors show the CLI message
  • @profview works from the first REPL prompt, and profiled code runs in Main
  • Jupyter cells show Plots as images again, and notebook output no longer shows internal markers
  • Send to REPL starts the visible REPL when it is stopped, and clearing plots no longer types code into it
  • The language server no longer starts and fails when LanguageServer.jl is not installed
  • The welcome dialog shows only once
  • Profiler snapshot names keep their underscores

Almost forgot to post, but I published a few bugfix releases. Chat, profiler, notebook, and REPL issues are fixed.
