ChatGPT changes constantly. This page tracks the public record: launches, model updates, feature rollouts, app releases, retirements, and important patches that OpenAI dated in an official release note.
Important limitation: OpenAI does not publish every internal deployment, experiment, server-side patch, or A/B test. ChatGPT on the web usually has no public patch number. “Complete” here means every public, dated OpenAI record captured from the official sources listed below—not a private engineering log.

| Deprecated | Developers or users were told to migrate away |

When this timeline can mislead
A date in a release note does not prove that every user received the feature that day. Rollouts can be limited by plan, region, device, workspace settings, age, capacity, or experiment group. An app-store version can also contain changes that OpenAI did not describe publicly.
Do not use this page as the only source for a legal deadline, security incident, API migration, or production deployment. Open the linked current documentation before acting.
