Today, we're moving one step closer to declaring the XenForo 1.5.0 as stable and supported. What is a Release Candidate? After a number of beta releases, the functionality of the product should be complete and the rate of bugs being reported (should) slow to a trickle, allowing the development team to work through the backlog and reduce the number of bugs to a handful. We have now reached this point in the development of XenForo 1.5.0, so the time is right to produce a release candidate. This means that the software is proposed as stable, and a period of time is allowed to verify the proposal. If no major bugs are found during that period, the software will be released as 1.5.0. If bugs are found that are considered sufficiently important to delay the release, we will see a further release candidate. This process continues until no significant bugs are discovered during the probation period for the latest release candidate. We recommend that all customers running previous 1.5 versions now upgrade to Release Candidate 1. All customers with active licenses may download XenForo 1.5.0 Release Candidate 1 from their customer area. This is Unsupported Software While we have moved on from the beta distinction, please remember that this release is not officially supported and we do not recommend running pre-release software in a production environment. Support is limited at this time to questions here on the community forums. If you choose to run unsupported software, it is your responsibility to ensure that you make a backup of your data. We recommend you do this before attempting an upgrade. Installation and Upgrade Instructions Full details for how to install and upgrade XenForo can be found in the XenForo Manual.
