JetBrains Marketplace Reflects PyCharm Changes
With the release of PyCharm 2025.1, PyCharm is now a single, unified product offering core features for free and a Pro subscription for advanced tools. In response to this change, JetBrains Marketplace has updated the way PyCharm category is displayed: the “PyCharm Community” has been removed from product filters and dropdowns, and “PyCharm Professional” has been renamed to “PyCharm.” Plugin compatibility labels have also been revised to clearly distinguish between plugins compatible with the full PyCharm IDE and those specific to the Community edition.
⭐️ Plugin development tooling updates
IntelliJ Plugin Verifier 1.388

Version 1.388 introduces several structural improvements and new features, including better handling of content module dependencies, support for Fleet products that follow IntelliJ versioning, and enhanced TeamCity recipe functionality. It also includes updates to ByteBuddy and Gradle, and fixes an issue with missing plugin-declared dependencies.

IntelliJ Platform Gradle Plugin 2.6.0
The IntelliJ Platform Gradle Plugin is a plugin for the Gradle build system to help configure your environment for building, testing, verifying, and publishing plugins for IntelliJ-based IDEs.
Version 2.6.0 brings new helper methods to simplify resolving plugin dependencies from JetBrains Marketplace, adds support for CSS and XML test frameworks, and improves task output and warnings for Plugin Verifier runs. It also deprecates Aqua (QA) as a target platform and includes a range of internal fixes and dependency resolution improvements.
