v2.2.0

pREST v2.2.0 — embedded Studio UI at /_studio/, database-backed custom queries, TimescaleDB E2E certification, and fully documented sample TOML.

Released: July 18, 2026

GitHub tag · Download binaries

v2.2.0 adds pREST Studio — an embedded admin and explorer UI at /_studio/ (#990) — plus database-backed custom query storage (#980), TimescaleDB E2E certification on the native PostgreSQL adapter (#988), and a fully documented sample configuration (#978).

  • Binary: v2.2.0 release assets

  • Docker: prest/prest:v2.2.0

  • Go install: go install github.com/prest/prest/v2/cmd/prestd@v2.2.0

Upgrading from v2.1.0 is a drop-in update. Studio is enabled by default; set PREST_STUDIO_ENABLED=false to turn it off. Custom query storage remains filesystem unless you opt into queries.storage = "database".

See Changes since v2.1.0 for the full commit list.

Highlights

pREST Studio (#990)

Self-hosted UI embedded in the prestd binary and served at /_studio/. Same-origin client of the existing REST and MCP APIs — no separate frontend process at runtime.

Database-backed custom queries (#980)

Optional queries.storage = "database" with prest_queries table, /_QUERIES/registry admin API, query ACL, and prestd migrate up|down queries. Default remains filesystem. See Custom Queries.

First-class integration tests for TimescaleDB through the native PostgreSQL adapter (still Compatible with caveats). See TimescaleDB.

Sample configuration (#978)

samples/prest.sample.toml documents every accepted key, including [studio] and [queries].

Upgrading from v2.1.0

No breaking changes for existing deployments.

  1. Deploy prest/prest:v2.2.0 (or the matching binary / go install …@v2.2.0).

  2. Open https://your-prest-host/_studio/ if you want the UI — or disable Studio if you prefer not to expose it.

  3. Optionally enable database-backed queries — see Custom Queries.

  4. MCP at /_mcp is unchanged from v2.1.0.
