Today, we continue the release candidate stage of XenForo 2.0 with Release Candidate 3. 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 2.0, 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 2.0.0. 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 2.0 versions now upgrade to Release Candidate 3. Once again, please pay attention to the following warnings: XenForo 2.0 is a significant upgrade from 1.x. Add-ons and customizations made for XenForo 1.x will not be compatible. Style customizations will need to be redone and will not be maintained after the upgrade. We strongly recommend you make a backup before attempting an upgrade. This is pre-release software. It is not officially supported. We do not recommend running it in production. All customers with active licenses may now download the new version from the customer area. Download XenForo 2.0.0 Release Candidate 3 -o- Download Official Add-ons Requirements Important: please always use corresponding versions of the official add-ons with the XenForo 2.0.0 pre-releases. If you choose to use the release candidate releases, you should always use the most recent version of all components. Please note that XenForo 2.0 has higher system requirements than XenForo 1.x. We will be updating the requirements test script in the near future to reflect this. The following are minimum requirements: PHP 5.4 or newer MySQL 5.5 and newer All of the official add-ons require XenForo 2.0. Enhanced Search requires at least Elasticsearch 2.0. Installation and Upgrade Instructions for XenForo 2.0 Full details for how to install and upgrade XenForo can be found in the XenForo Manual. While XenForo 2 has a different appearance compared to XenForo 1, the installation and upgrade process is largely unchanged. Installation, Upgrading and Configuration of Add-ons To upgrade or install these add-ons, you should upload the contents of the upload folder (not the upload folder itself) to the root XenForo directory. It is important that the files you upload are "merged" with the existing files on your server; no files on the server should be deleted as part of your upload. Once uploaded, head to the add-ons section of your control panel. The add-ons should be listed as installable or upgradable. If they are not, please confirm that you uploaded them to the correct location. Please remember that this is pre-release software. It contains known bugs and incomplete functionality. We do not recommend or support running pre-release software in a production environment. Support for release candidate releases is limited to questions here on the community forums.
