Vercel has patched a gap in its deployment retention system: the latest preview deployment for any branch with an open or unmerged pull request will no longer be deleted, regardless of your configured retention window.
This matters because teams using aggressive retention windows to control storage costs were silently losing active preview deployments on live branches. Now you can tighten that window without collateral damage to in-progress work. The fix applies across all plans at no tier restriction.
The existing guarantees still hold: your 10 most recent production deployments and any aliased deployments remain protected independent of retention settings. The full documentation on Deployment Retention is worth reading to understand exactly how these preservation rules stack and interact.
