Today we release JIRA Client 3.0.1, which contains a few fixes and improvements. Here are some of them:
You can also check a more detailed list of changes in our JIRA.
If you are upgrading from JIRA Client 3.0, simply install the new version over the old one, run JIRA Client, and wait until it finishes synchronizing JIRA configuration.
Otherwise, follow the instructions for upgrading from JIRA Client 2.x or earlier.
If your JIRA has JIRA Client plugin installed, you'll need a Marketplace version which can be obtained via the download link in your user profile menu in the top right corner of any JIRA web page.
Non-marketplace license users can download JIRA Client or JIRA Client Lite on the main download page. You can use JIRA Client in a free 30-day trial mode or with any old-style team license with an active maintenance subscription. JIRA Client Lite may be used freely with any JIRA server running on a Starter license, or with a JIRA server that hosts a sponsored open-source project.
