Hi Team, As part of supporting IntelliJ IDEA version 2025.2 builds, I’ve uploaded our plugin ZIP file to the JetBrains Marketplace and reviewed the scan results. I noticed the usage of the following deprecated APIs: CefLocalRequestHandler CefStreamResourceHandler Could you please clarify t…

We don’t remove APIs in minor updates so it will take at least full release cycle to 2025.3, but also we don’t promise to remove it next release. It depends on cleanup in our monorepo and clients still using it

However, HIDE_OTHER_EDITORS is currently marked as @ApiStatus.Experimental . We are currently using FileEditorPolicy.HIDE_OTHER_EDITORS to control editor behavior…

For the record, HIDE_DEFAULT_EDITOR is discussed elsewhere. [image] Recommended fallback or migration strategy for FileEditorPolicy.HIDE_OTHER_EDITORS (Experimental API) IntelliJ Platform I noticed from the Javadoc that HIDE_DEFAULT_EDITOR recommends using Fil…
