A user says your plugin froze their IDE. You can't reproduce it.

JetBrains Marketplace now shows freeze reports linked to your plugin, with excerpts and full thread dumps.

I made a short walkthrough of the setup and investigation:

There's no time to rest! While still at the airport, on my way back from Devoxx, I published a blog post about a new JetBrains Marketplace feature we rolled out!

If you're attending @Devoxx Belgium and develop plugins for JetBrains IDEs, make sure to say hi to @hszanowski!

[Jakub Chrzanowski 🥑 @hszanowski]

Even if you’re in a rush like Kodee and Runzo, make sure to stop by the JetBrains booth at @Devoxx Belgium! 🏃‍♂️💨

We’ll show you what JetBrains Air is and how to get started with it. And yes, there are free socks to keep you comfy while you code. 🧦💜

We love seeing what third-party devs build on IntelliJ Platform ❤️

Small update, big convenience 👇

🧩 Plugin descriptions can now be edited directly on the plugin's page. The description is stored separately from the plugin archive, so you don't need to upload a new plugin version to update it.

Starting a JetBrains IDE plugin just got simpler.

The new IDE Plugin Generator combines the IDE wizard and the GitHub template into a single flow. Choose features, preview the project, then generate it in IntelliJ IDEA 2026.1+ or your browser.

A blog post about open-sourcing the LSP API in IntelliJ IDEA 2026.2 is live! 🧠

😮 Plot twist: the work is also planned for 2026.1.4 stable, so Android Studio support may arrive earlier than 2026.2.

Plugin authors: if you save through VFS and then hand a file path to a CLI, formatter, VCS command, or Java file API, check this.

VFS may see fresh content before the disk does.

If the next reader is outside VFS, flush first.

IntelliJ Platform plugin devs are getting "ErrorReportSink": an experimental API for automatic error and freeze reporting.

Stop asking users to paste tokens into plugin settings!

I recorded a video about adding OAuth2 login to JetBrains IDE plugins: browser login, IDE callback, PKCE, PasswordSafe, and GitHub API calls
