## [Unreleased]

## [2.2.2] - 2026-06-01

### Fixed

- **Passthrough mode memory leak**: Fixed a per-statement memory leak that occurred in passthrough mode (empty encrypt config), where per-statement queues were not drained. Long-running connections could grow unbounded and eventually OOM. ([#400](https://github.com/cipherstash/proxy/issues/400))

## [2.2.1] - 2026-05-14
Comment thread
coderabbitai[bot] marked this conversation as resolved.

### Added

- **OPE (Order-Preserving Encryption) index**: New `ope` index type alongside the existing `ore` for range and `ORDER BY` queries on encrypted columns. Drop-in alternative to `ore` — pick one per column. See the [encrypted indexes documentation](docs/how-to/index.md) for configuration.
