Netlify is introducing the ability for team Owners and Collaborators to manually delete any deploy from the Netlify UI, providing peace of mind over old deploys. This feature allows users to permanently delete a deploy, removing all related artifacts, including deploy logs and URLs. However, deleting a deploy is permanent and cannot be undone, and it may disrupt split testing or cause issues with A/B tests referencing the deleted deploy. Additionally, Netlify will automatically delete failed or canceled deploys older than 6 months as part of its new "automated deploy cleanup" feature, aiming to reduce clutter in the timeline and improve sustainability.
