Ruby 3.3.11 Released
Ruby 3.3.11 has been released. This release includes an update to the zlib gem addressing CVE-2026-27820 , along with some bug fixes. Please see the GitHub releases for further details. This is the last release of normal maintenance for the Ruby 3.3 series. After this release, Ruby 3.3 enters a security maintenance phase. During this phase, we will only backport security fixes and fixes for critical build issues, without any regular bug fixes. The security maintenance phase is scheduled to last for one year, until the end of March 2027. At that point, official support for Ruby 3.3 will end. We recommend that you begin planning your migration to Ruby 3.4 or 4.0.

Ruby 3.3.11 Released
The Ruby community has announced the release of Ruby 3.3.11, marking the final normal maintenance release for the Ruby 3.3 series. This version includes an update to the zlib gem that addresses the security vulnerability CVE-2026-27820, along with several bug fixes. The release notes and detailed information can be found in the GitHub releases section.
This release is significant because it signifies the end of regular maintenance for Ruby 3.3. Following this, the Ruby 3.3 series will enter a security maintenance phase, which will last for one year until the end of March 2027. During this period, the Ruby team will only backport security fixes and address critical build issues, without providing regular bug fixes. After the security maintenance phase concludes, official support for Ruby 3.3 will be discontinued.
Developers and users are advised to begin planning their migration to newer Ruby versions, such as Ruby 3.4 or Ruby 4.0, to ensure continued support and access to new features and improvements. The Ruby community encourages users to update their systems to the latest stable versions to benefit from ongoing enhancements and security updates.
Ruby 3.3.11 is available for download from the official Ruby website. The release includes three different file formats: a tarball (.tar.gz), a xz-compressed tarball (.tar.xz), and a zip archive (.zip). Each file comes with its respective SHA1, SHA256, and SHA512 checksums for verification purposes.
The Ruby team expresses gratitude to the numerous committers, developers, and users who contributed bug reports and assistance that helped shape this release. Their efforts have been instrumental in ensuring the stability and security of the Ruby ecosystem.
In conclusion, the Ruby 3.3.11 release is a critical update for those still using the Ruby 3.3 series. It addresses a significant security vulnerability and includes bug fixes. However, users are advised to plan their migration to newer Ruby versions to continue receiving regular updates and support. The Ruby community remains committed to providing a secure and robust programming environment for developers worldwide.
