Ktor 3.4.0 Is Now Available! | The Kotlin Blog

Ktor 3.4.0 introduces several enhancements focused on improving stability and addressing outstanding issues, including the completion of OpenAPI generation for dynamic endpoint documentation, duplex streaming support for OkHttp enabling simultaneous request and response data flow, and Zstd compression for high efficiency in the compression plugin. Additionally, the new HttpRequestLifecycle plugin allows for cancelling in-flight HTTP requests when clients disconnect, enhancing resource management through structured concurrency. These updates aim to bolster Ktor's performance and readiness for future development, encouraging community involvement through the Ktor Early Access Program and offering resources for starting new projects at start.ktor.io.
