We're releasing JIRA Client version 1.5.1 today. This is mostly a bug-fix release, dealing with issues that have been reported in version 1.5 and some older issues.
After beta version of JIRA 4 was announced on Atlassian Summit, we immediately installed it to check if JIRA Client works with the bleeding edge JIRA server. To our surprise and joy, most of the things worked — thanks to Atlassian developers for preserving backward compatibility! But we still had to make a few changes and now all features of JIRA Client 1.5.1 are compatible with JIRA 4 beta.
Upgrade is advised to everyone using JIRA Client, because there were some major problems fixed with this release. Before upgrading to the new version, please back up your workspace.
