September 2025 monthly summary for JetBrains/intellij-community focusing on Kotlin feature improvements, stability fixes, and user experience enhancements. The sprint delivered user-visible improvements in string literal handling, better paste/copy-paste UX in K2 mode, and a clarifying update to the inspection naming, while also removing a flaky test to boost CI stability.
