• Security warnings in Jenkins

  Jenkins 2.40 was released earlier this week, and readers of the changelog will have noticed that it now includes the ability to show security warnings published by the configured update site.

  Last week we released version 0.7.1 of the Pipeline-Model-Definition plugin and wanted to crown it as the official Beta version of the Declarative Pipeline syntax.
