Supabase CLI now exposes the experimental flags needed to spin up OrioleDB managed projects, while the evals system abandons GitHub Actions for faster, sandboxed test execution.

The CLI's `projects create` command now accepts `--postgres-engine 17-oriole` to provision OrioleDB instances directly, ending the workaround of manual API calls [1]. This lands alongside two quality-of-life fixes: the update notifier can now be silenced with `SUPABASE_NO_UPDATE_NOTIFIER` [2], and Windows developers finally get working `migration new` that doesn't lose files to tmpfs vanishing [3]. Docker Snap users also got relief; secrets now stream as tar archives instead of failing when the host's `/tmp` is invisible to the container [4]. On the evals front, the bigger shift is architectural: test execution moved from GitHub Actions to Vercel Sandboxes with p-limit and p-retry for concurrency [6], while the Row Level Security eval was retooled to actually measure whether reading the guide produces secure policies, not just recite it [5]. A parser fix ensures claude-code tool calls match Codex behavior for scoring consistency [7].

Action items

→ If you manage OrioleDB projects, test the new --postgres-engine 17-oriole flag before production use supabase/cli [plan]
→ Set SUPABASE_NO_UPDATE_NOTIFIER=1 in CI environments if update notices clutter logs supabase/cli [monitor]
→ Windows users: upgrade CLI to get reliable migration creation supabase/cli [plan]
→ Docker Snap users: patch to fix `supabase start` secret copy failures supabase/cli [immediate]
