@WebStormIDE Is the Svelte extension still being maintained? It doesn’t feel like it.

@GyenAbubakar Thanks for the question! Our team lead actually shared an update about Svelte support in today’s AMA session.
In short, maintenance is ongoing, but a deeper rework is being evaluated, with 2026.1 as the earliest target.

@WebStormIDE Guys, thank you for the long-awaited release!

However, in the new release, as in all 2025.3 builds (eap, rc), git does not work in wsl.

The problem is described here: youtrack.jetbrains.com/issue/IJPL-219…
