There is now a message on the Second Life JIRA homepage that the final shutdown will be on the 15th of February 2024. The Second Life JIRA is currently down now for migration over to GitHub and logins are currently restricted to Lindens only. It will be restored soon to non Linden accounts until the final shutdown deadline which is fast approaching.
New Second Life Feedback Portal
It’s now recommended for everyone to use the new Second Life Feedback portal to report new bugs and new feature requests. There are Second Life boards for Feature Requests, Viewer Bug Reports, Web/Marketplace Features/Bugs, Scripting Features and Mobile Alpha boards for the latest development reports.
It’s worth bookmarking the new Second Life Feedback portal website and spreading the word about this.
