The calendar of dates
Model retirements, runtime end of life, certificates, domains and Apple’s requirements.
The Calendar lists the dates that quietly break things, a year ahead:
- AI models: the exact models your code names, against each vendor's own retirement table. A dated version's short name counts ("gpt-4o"), but a different model never does.
- Runtimes: Node.js and Python versions your repo pins, against their published end of life.
- Your domain: its certificate and its registration. Certificates your host renews by itself are listed under Renews by itself.
- Apple: upcoming App Store requirements, for apps that ship to the App Store.
