# 0.3.12 (Jun 29, 2022)

This release of `tracing-subscriber` adds a new `Layer::event_enabled`
method, which allows `Layer`s to filter events *after* their field
values are recorded; a `Filter` implementation for `reload::Layer`, to
make using `reload` with per-layer filtering more ergonomic, and
additional inherent method downcasting APIs for the `Layered` type. In
addition, it includes dependency updates, and minor fixes for
documentation and feature flagging.

### Added

- **layer**: `Layer::event_enabled` method, which can be implemented to
  filter events based on their field values (#2008)
- **reload**: `Filter` implementation for `reload::Layer` (#2159)
- **layer**: `Layered::downcast_ref` and `Layered::is` inherent methods
  (#2160)

### Changed

- **parking_lot**: Updated dependency on `parking_lot` to 0.13.0
  (#2143)
- Replaced `lazy_static` dependency with `once_cell` (#2147)

### Fixed

- Don't enable `tracing-core` features by default (#2107)
- Several documentation link and typo fixes (#2064, #2068, #2077,
  #2161, #1088)

## Motivation

There's a broken link and broken formatting in the [mod-level docs] for
`tracing_subscriber::layer` referring to the `Layer` impl for `Vec`s of
`Layer`s. Looks like it got mangled by search+replace in tokio-rs#2038 so it's
not an issue in master.

[mod-level docs]: https://docs.rs/tracing-subscriber/0.3.11/tracing_subscriber/layer/index.html#runtime-configuration-with-layers

## Solution

I have stolen the correct markdown and link from master.
