About Kotlin 1.7
Kotlin 1.7 reached end of life over 3 years ago on December 28, 2022. It no longer receives security patches, bug fixes, or any form of official support. Running this version in production exposes your systems to unpatched vulnerabilities and growing incompatibility with modern libraries and tooling.
Upgrade to Kotlin 2.3 for continued security coverage and access to the latest features. The upgrade from 1.7 to 2.3 is typically straightforward, but review the release notes for any deprecations or API changes.
