Six Apart’s primary goal is to help make Movable Type a safer and even more dependable product. In an effort to make it easier for our customers to keep their installed version of Movable Type up dated to the latest version of software, which provides the most effective form of protection against security threats, Six Apart has created the new “Product Life Cycle Policy.” This policy is reflected retroactively including previously released version of Movable Type as well as all subsequent upgrades and new versions. We hope the following information will be helpful in getting your version of Movable Type updated to the latest and most secure version of the software available.
Below are definitions for the different lifecycle phases included in the chart below
During the period between GA and EOS (End of Sales), security patches and bug fixes will be released on a regular basis, with official technical support available for a fee.
EOS designates the closure of sales for a specific product version. Major (x.0) and feature (0.x) releases for the product version released during the GA period will start to become available. Once EOS has passed, the product version released during the GA period will no longer be available for purchase. Bug fixes (0.0x) and security updates will continue to be released until EOM (End of Maintenance), and official technical support will continue to be available for a fee.
EOM signifies the end of official Six Apart maintenance support for a specific product version. EOM occurs 12 months after EOS (End of Sales). At this point, the product version will go into what is defined by Six Apart as a security maintenance period: only patches for security breaches deemed critical by Six Apart will continue to be released until EOL (End of Life). It is possible to continue using the product at this time, however the user must understand that, following EOM, official technical support will no longer be available. In addition, only the latest version of the most recent feature release will be classified as EOM, with all previous versions classified as EOL (End of Life). If official technical support is necessary, the user will first have to upgrade to the most recent product release.
EOL signifies that a product version has reached the end of it’s life span. It will no longer go under maintenance and will no longer receive bug fixes, security patches, or additional feature updates. Third party support may remain available, but there will no longer be any official Six Apart technical support. It is possible to continue using the product at this time, however the user must be aware of the security risk in doing so. It is strongly recommended that the user upgrade to the most recent version of the product before EOL occurs.
