Acquia is committed to maintain security and stability of Cloud Platform. To do so, Acquia removes software that reach end-of-life, and adds new features. Whenever such an event occurs, Acquia updates documentation and shares communication around these events. Acquia provides adequate lead time to ensure that your application continues to run smoothly when these upgrade and retirement efforts are underway. For more information about upcoming maintenance events, see Software end-of-life schedule.
