This is a genuinely useful weekly digest — the retirement-date item is the one I'd flag first. GPT-4o and GPT-5.1 timelines shifting means teams need to re-check their migration windows rather than assume the old dates still hold. The lockable point-in-time restore for Azure SQL stood out too; in regulated environments, being able to lock a retention window so it can't be quietly shortened is a real safeguard. And the Foundry extension for azd going GA is the practical one for teams actually shipping AI features. Thanks for pulling it all into one place.
