# 0.2.4 (April 6, 2020)

This release includes several API ergonomics improvements, including
shorthand constructors for many types, and an extension trait for
initializing subscribers using method-chaining style. Additionally,
several bugs in less commonly used `fmt` APIs were fixed.

### Added

- **fmt**: Shorthand free functions for constructing most types in `fmt`
  (including `tracing_subscriber::fmt()` to return a
  `SubscriberBuilder`, `tracing_subscriber::fmt::layer()` to return a
  format `Layer`, etc) (#660)
- **registry**: Shorthand free function `tracing_subscriber::registry()`
  to construct a new registry (#660)
- Added `SubscriberInitExt` extension trait for more ergonomic
  subscriber initialization (#660)
  
### Changed

- **fmt**: Moved `LayerBuilder` methods to `Layer` (#655)

### Deprecated

- **fmt**: `LayerBuilder`, as `Layer` now implements all builder methods
  (#655)
  
### Fixed

- **fmt**: Fixed `Compact` formatter not omitting levels with
  `with_level(false)` (#657)
- **fmt**: Fixed `fmt::Layer` duplicating the fields for a new span if
  another layer has already formatted its fields (#634)
- **fmt**: Added missing space when using `record` to add new fields to
  a span that already has fields (#659)
- Updated outdated documentation (#647)
