+
+This release adds *experimental* support for recording structured field
+values using the [`valuable`] crate. See [this blog post][post] for
+details on `valuable`.
+
+Note that `valuable` support currently requires `--cfg tracing_unstable`. See
+the documentation for details.
+
+This release also adds a new `enabled!` macro for testing if a span or event
+would be enabled.
+
+### Added
+
+- **field**: Experimental support for recording field values using the
+  [`valuable`] crate ([#1608], [#1888], [#1887])
+- `enabled!` macro for testing if a span or event is enabled ([#1882])
+
+### Changed
+
+- `tracing-core`: updated to [0.1.22][core-0.1.22]
+- `tracing-attributes`: updated to [0.1.19][attributes-0.1.19]
+
+### Fixed
+
+- **log**: Fixed "use of moved value" compiler error when the "log" feature is
+  enabled ([#1823])
+- Fixed macro hygiene issues when used in a crate that defines its own `concat!`
+  macro ([#1842])
+- A very large number of documentation fixes and improvements.
