# 0.2.0 (October 22, 2021)
This breaking change release adds support for the new v0.3.x series of
`tracing-subscriber`. In addition, it resolves the security advisory for
the `chrono` crate, [RUSTSEC-2020-0159].
This release increases the minimum supported Rust version (MSRV) to
1.51.0.
### Breaking Changes
- Updated `tracing-subscriber` to v0.3.x ([#1677])
- Changed `NonBlocking::error_counter` to return an `ErrorCounter` type,
rather than an `Arc<AtomicU64>` ([#1675])
### Changed
- Updated `tracing-subscriber` to v0.3.x ([#1677])
### Fixed
- **non-blocking**: Fixed compilation on 32-bit targets ([#1675])
- **rolling**: Replaced `chrono` dependency with `time` to resolve
[RUSTSEC-2020-0159] ([#1652])
- **rolling**: Fixed an issue where `RollingFileAppender` would fail to
print errors that occurred while flushing a previous logfile ([#1604])
Thanks to new contributors @dzvon and @zvkemp for contributing to this
release!
