+## [5.0.0] - 2025-04-25
+### Changed
+ - Upgrade to JRuby 10.0.0.0 (Ruby 3.4.2)
+ - Upgrade to Groovy 4.0.26
+ - Upgrade to Kotlin 2.1.20
+
+### Fixed
+ - Ruby console errors on non-Windows systems related to the terminal not using
+   the typical STDIN file descriptor.
+ - Kotlin engine startup now includes a warm-up evaluation so that the first
+   user expression does not have to wait for this.

 ## [4.2.0] - 2025-02-14
 ### Changed
  - Upgrade to JRuby 9.4.12.0 (Ruby 3.1.4)
