Kotlin 2.5 Changes Its Publishing Format, and the Compiler Gets Stricter
On October 21, Kotlin 2.5.0-Beta2 shipped. Most people open the notes, read the four promoted and two experimental language features, decide it is unremarkable, and close the tab.
Amper Got Promoted: It Is Now the Kotlin Toolchain
On October 6, JetBrains’ Amper blog published its final post, titled Amper Is Now the Kotlin Toolchain. The name carries a line underneath, Moving to the Kotlin Blog, and it means what it says: that blog stops updating as of that day and merges into the Kotlin blog.

ADK for Kotlin 1.1 + Ktor 3.6: An AI Agent Primer for KMP Developers
Python’s agent frameworks have already cycled through several generations — LangChain, LlamaIndex, and now Google’s own ADK. Kotlin has been quiet the whole time — not because nobody wanted to build one, but because there was nothing official to lean on, and nobody quite dared put it in production.
