## 2026.08.0

- Add Snowflake-Next preview, a new-generation emulator planned to become the default soon. In internal testing it ran the regression suite more than 10 times faster than the current emulator. Enable it to try `STREAM` (including `STREAM ON VIEW`), zero-copy `CLONE`, and Time Travel.
- `RESULT_SCAN` now processes results from `SHOW`, `DESC`, `LIST`, and other status-returning commands, handles empty `SHOW` results, and returns Snowflake-style errors for failed or in-progress queries instead of unrelated syntax errors.
- `LISTAGG` and `ARRAY_AGG` support multiple ordered aggregates with separate `WITHIN GROUP` clauses in a single `SELECT` statement, each using independent ordering.
- Long-running queries now remain in progress until execution finishes, instead of returning early.
- `SHOW <objects> IN SCHEMA` now limits results to the requested schema for views, materialized views, sequences, and file formats.
- `SHOW VIEWS` identifies materialized views via the `is_materialized` field; `SHOW MATERIALIZED VIEWS` returns the view definition in the `text` field.
- `ALTER PIPE`, `DESC PIPE`, and `DROP PIPE` now resolve fully qualified names independent of the session's current schema.
- `DROP PIPE IF EXISTS` no longer errors when the pipe doesn't exist.
- `CREATE TAG IF NOT EXISTS` is now idempotent.
- Dropping a database or schema now removes only the tags it owns, preserving tags in other namespaces.
- Migrate the Docker image base from Debian sid (rolling) to Debian trixie (stable release).

## 2026.07.0

- Tables and data stored with `PERSISTENCE=1` remain available after the emulator restarts.
