I am the maintainer of the ktlint-intellij-plugin. Currently I am trying to upgrade the plugin so that it can be used in Idea 2025.3 EAP version. The Plugin Verifier fails on retrieving ideaIC:253.22441.33 with message below:

> Could not resolve all files for configuration ':ktlint-plugin:detachedConfiguration7'.
   > Could not find idea:ideaIC:253.22441.33.
     Searched in the following locations:

     Required by:
         project :ktlint-plugin

This makes sense, given the move to the unified distribution. Also the latest builds page indicates that the above version is invalid, and that I should use platform type IU instead of IC .

The build of the plugin is based on the intellij plugin template, In the properties, following is configured:

# IntelliJ Platform Properties -> <https://plugins.jetbrains.com/docs/intellij/tools-gradle-intellij-plugin.html#configuration-intellij-extension>
platformType = IC
platformVersion = 2024.1.7

I expect that changing platformType from IC to IU will fix the verification problem for Idea 2025.3. I am concerned though that the new release of the plugin will not be usable anymore for users of the older (2025.2 and before) Community Editions. Is this concern valid? Or should I make changes (if so, please advise) to remediate this?
