### Enhancements
- Added dYdX integration (#1861, #1868, #1873, #1874, #1875, #1877, #1879, #1880, #1882, #1886, #1887, #1890, #1891, #1896, #1901, #1903, #1907, #1910, #1911, #1913, #1915), thanks @davidsblom
- Added composite bar types, bars aggregated from other bar types (#1859, #1885, #1888, #1894, #1905), thanks @faysou
- Added `OrderBookDeltas.batch` for batching groups of deltas based on record flags (batch until `F_LAST`)
- Added `OrderBookDeltas` batching support for `ParquetDataCatalog` (use `data_cls` of `OrderBookDeltas` to batch with the same flags method as live adapters)
- Added `RetryManagerPool` to abstract common retry functionality for all adapters
- Added `InstrumentClose` functionality for `OrderMatchingEngine`, thanks @limx0
- Added `BacktestRunConfig.dispose_on_completion` config setting to control post-run disposal behavior for each internal backtest engine (`True` by default to retain current behavior)
- Added `recv_window_ms` config setting for `BinanceExecClientConfig`
- Added `sl_time_in_force` and `tp_time_in_force` parameters to `OrderFactory.bracket(...)` method
- Added custom `client_order_id` parameters to `OrderFactory` methods
- Added support for Binance RSA and Ed25519 API key types (#1908), thanks @NextThread
- Added `multiplier` parameter for `CryptoPerpetual` (default 1)
- Implemented `BybitExecutionClient` retry logic for `submit_order`, `modify_order`, `cancel_order` and `cancel_all_orders`
- Improved error modeling and handling in Rust (#1866), thanks @twitu
- Improved `HttpClient` error handling and added `HttpClientError` exception for Python (#1872), thanks @twitu
- Improved `WebSocketClient` error handling and added `WebSocketClientError` exception for Python (#1876), thanks @twitu
- Improved `WebSocketClient.send_text` efficiency (now accepts UTF-8 encoded bytes, rather than a Python string)
- Improved `@customdataclass` decorator with `date` field and refined `__repr__` (#1900, #1906, #1909), thanks @faysou
- Improved standardization of `OrderBookDeltas` parsing and records flags for crypto venues
- Refactored `RedisMessageBusDatabase` to tokio tasks
- Refactored `RedisCacheDatabase` to tokio tasks
- Upgraded `tokio` crate to v1.40.0

### Breaking Changes
- Renamed `heartbeat_interval` to `heartbeat_interval_secs` (more explicitly indicates time units)
- Moved `heartbeat_interval_secs` config setting to `MessageBusConfig` (the message bus handles external stream processing)
- Changed `WebSocketClient.send_text(...)` to take `data` as `bytes` rather than `str`
- Changed `CryptoPerpetual` Arrow schema to include `multiplier` field
- Changed `CryptoFuture` Arrow schema to include `multiplier` field

### Fixes
- Fixed `OrderBook` memory deallocation in Python finalizer (memory was not being freed on object destruction), thanks for reporting @zeyuhuan
- Fixed `Order` tags serialization (was not concatenating to a single string), thanks for reporting @DevRoss
- Fixed `types_filter` serialization in `MessageBusConfig` during kernel setup
- Fixed `InstrumentProvider` handling of `load_ids_on_start` when elements are already `InstrumentId`s
- Fixed `InstrumentProviderConfig` hashing for `filters` field
