- Fixed a bug where the single-sign-on oidc code would generate an unbounded amount of cookies when receiving many unauthenticated requests in sequence.
- Fix: invalid UTF-8 in multipart text fields now returns `400 Bad Request` instead of `500 Internal Server Error`.
- Logging: `LOG_LEVEL` is now the primary environment variable for configuring SQLPage's log filter. `RUST_LOG` remains supported as an alias.
