# Changelog

## 0.37.0 - 2025-12-09

### Enhancements
- Added optional `chrono` feature for converting `chrono` date and datetime types to
`DateRange`, `DateTimeRange`, and `Subscription::start` (credit: @wtn)
- Upgraded DBN version to 0.45.0:
- Added new venue, dataset, and publisher for Cboe Futures Exchange (`XCBF.PITCH`)


### Breaking changes
- Changed the default to `true` for the `map_symbols` parameter in
`SubmitJobParams::builder()` for JSON and CSV encodings
- Moved `DateTimeLike` trait to top level

### Bug fixes
- Fixed checksum verification for resumed downloads in `batch().download()`. Previously,
it would erroneously fail

## 0.36.0 - 2025-11-19

- `historical`: enables the historical client for data older than 24 hours
- `live`: enables the live client for real-time and intraday historical data
- `chrono`: enables passing `chrono` types as datetime parameters

By default both features are enabled and the historical client uses OpenSSL for TLS.
To use `rustls`, disable default features for both the databento crate and [reqwest](https://github.com/seanmonstar/reqwest).
