Monthly performance summary for 2025-08 focusing on delivered features and fixes within JetBrains/intellij-community. The key deliverable is enabling flexible module configuration for KaScriptModuleBase by allowing subclasses to declare their own SDK dependencies, which simplifies customization and enhances module configurability for plugin developers. This change improves per-module customization, reduces boilerplate, and supports more predictable build configurations, aligning with the project’s goals of ecosystem flexibility and developer productivity.

May 2025 monthly summary: Focused on boosting notebook interoperability and script/plugin safety in Kotlin projects. Deliverables include a descriptor establishing the OpenAI Java integration in the Kotlin/Jupyter libraries, enabling Java-based apps to configure and use OpenAI services with minimal setup. In Kotlin core, Notebook ScriptPlugin enhancements enabled registration of compiler plugins for ScriptSession to support DataFrame and Repl plugins in notebooks, with tests added for Script local classes to validate behavior. A related DataFrame plugin improvement added FirScript API exposure safety by introducing isInsideFirScript to avoid unnecessary API exposure checks in FirScript code, aligning behavior with the top-level nature of scripts. These changes collectively improve business value by enabling Java/OpenAI interoperability in notebooks, expanding scripting capabilities in data science workflows, and increasing safety and test coverage for compiler plugin contexts.
