Release Schedule

We intend to release the latest stable Ruby version (currently Ruby 3.4) every two months following the most recent release. Following this release (3.4.4), Ruby 3.4.5 is scheduled for July, 3.4.6 for September, 3.4.7 for November, and 3.4.8 for January.

If a change arises that significantly affects users, a release may occur earlier than planned, and the subsequent schedule may shift accordingly.
