 ## Upgrade Notice: Groovy 4 Compatibility
 
 **Artifactory Version: 7.101 (released November 25, 2024 for cloud)**
 
 Artifactory has been upgraded to Groovy 4 starting from version 7.101. This includes several important updates, most notably the promotion plugin (JFrog Supported), updated for compatibility with Groovy 4. However, this upgrade may break compatibility with your custom plugins developed for earlier Groovy versions (Groovy 3 or older). To learn the differences between Groovy 3 and 4, refer to [Release notes for Groovy 4.0
