- 08-05 GitHub: GitHub Spark shuts down on 27 days' notice
GitHub announced on 2026-08-04 that Spark stops accepting new users and new apps immediately, with existing users given until 2026-08-31 to export their work; already-deployed apps keep running, but any app using the `llm()` function needs a new inference provider since GitHub Models (the service behind it) retired 2026-07-30. It is the shortest deprecation window in this site's running comparison — about 27 days' notice against MCP's 12-month offramp, GitHub Models' own six weeks, and HCP Vagrant Registry's 21 months.
- 08-04 HashiCorp: A hosted registry retires on a 21-month clock
HashiCorp is retiring the HCP Vagrant Registry in three dated phases — new box creation stops 2026-12-14, support ends 2027-03-15, all operations cease 2027-06-07 — with documented S3 export guidance and the open-source community edition kept alive as the fallback. It is the longest migration window on record in this site's deprecation-window comparisons, ahead of MCP's 12-month offramp and well past GitHub Models' six weeks.
