### Fixed
- `EnvFilter` ignoring directives with targets that are the same number
of characters (#333)
- `EnvFilter` failing to properly apply filter directives to events
generated from `log` records by`tracing-log` (#344)
### Changed
- Renamed `Filter` to `EnvFilter`, deprecated `Filter` (#339)
- Renamed "filter" feature flag to "env-filter", deprecated "filter" (#339)
- `FmtSubscriber` now defaults to enabling only the `INFO` level and
above when a max level filter or `EnvFilter` is not set (#336)
### Added:
- `EnvFilter::add_directive` to add new directives to filters after they
are constructed (#334)
- `fmt::Builder::with_max_level` to set a global level filter for a
`FmtSubscriber` without requiring the use of `EnvFilter` (#336)
- `Layer` implementation for `LevelFilter` (#336)
- `EnvFilter` now implements `fmt::Display` (#329)

chore: build and publish documentation for each branch.
This commit introduces support for:
- building and deploying documentation for the master branch
- building and deploying (preview) documentation for each pull request
and for each PR
- adds a link in `README.md` pointing to the generated documentation
for the master branch
- notes the per-PR documentation previews in `CONTRIBUTING.md`
Closes#210
## Motivation
There's been demand for a crates.io release of the `tracing-subscriber`
crate, particularly so that the `Layer` type (which is relatively
stable) may be used in other crates.
## Solution
This branch prepares `tracing-subscriber` to release an alpha. I've
updated the documentation and Cargo.toml, and added a README.
* subscriber: rm unneeded dev-dependency
* subscriber: add README
* subscriber: add lib.rs docs
* subscriber: update README
