A legacy product is one that is no longer under active development but has yet to be fully retired. This is not an automatic designation, and when it happens, it will be publicly announced through all our major channels of communication. Legacy products are no longer available for purchase, and no software defects will be fixed (including new issues) with the exception of major security concerns and defects that result in data loss. Official support for legacy products is included with an EllisLab Support plan.
Once a product is designated a legacy product, it will automatically become a retired product 1 year later. Retired products no longer receive updates of any kind, and are no longer eligible for support beyond help with upgrades. You can find a full list of major versions and their status here.
If you have an issue with a retired site and need expert help, ExpressionEngine services may be right for you.
