Looks good. Thank you very much!
Just one small change
Currently, Span.record_all() is part of the public API and accepts ValueSet as a parameter. However, constructing a ValueSet is both verbose and undocumented, making it not so practical. To make recording multiple values easier, we introduce a new macro: record_all!, which wraps the Span.record_all() function. As we don't intend anyone to call Span.record_all() directly, we hide it from the documentation. We reference the new macro from Span.record() doc comment instead. The new record_all! macro supports optional formatting sigils % and ?, ensuring a consistent DevEx with the other value-recording macros.

When developing the test, I realized that the previous iteration would not support plain primitive values, such as integers or booleans. Given that span! macro supports that, I thought it to be reasonable for record_all! to do so as well. This version does. It is also simpler than the original. Looking forward to feedback!

# 0.1.42 (November 26, 2025) ### Added - **attributes**: Support constant expressions as instrument field names ([#3158]) - Add `record_all!` macro for recording multiple values in one call ([#3227]) - **core**: Improve code generation at trace points significantly ([#3398]) ### Changed - `tracing-core`: updated to 0.1.35 ([#3414]) - `tracing-attributes`: updated to 0.1.31 ([#3417]) ### Fixed - Fix "name / parent" variant of `event!` ([#2983]) - Remove 'r#' prefix from raw identifiers in field names ([#3130]) - Fix perf regression when `release_max_level_*` not set ([#3373]) - Use imported instead of fully qualified path ([#3374]) - Make `valueset` macro sanitary ([#3382]) ### Documented - **core**: Add missing `dyn` keyword in `Visit` documentation code sample ([#3387]) [#2983]: https://github.com/tokio-rs/tracing/pull/#2983 [#3130]: https://github.com/tokio-rs/tracing/pull/#3130 [#3158]: https://github.com/tokio-rs/tracing/pull/#3158 [#3227]: https://github.com/tokio-rs/tracing/pull/#3227 [#3373]: https://github.com/tokio-rs/tracing/pull/#3373 [#3374]: https://github.com/tokio-rs/tracing/pull/#3374 [#3382]: https://github.com/tokio-rs/tracing/pull/#3382 [#3387]: https://github.com/tokio-rs/tracing/pull/#3387 [#3398]: https://github.com/tokio-rs/tracing/pull/#3398 [#3414]: https://github.com/tokio-rs/tracing/pull/#3414 [#3417]: https://github.com/tokio-rs/tracing/pull/#3417

# 0.1.42 (November 26, 2025) ### Important The [`Span::record_all`] method has been removed from the documented API. It was always unsuable via the documented API as it requried a `ValueSet` which has no publically documented constructors. The method remains, but should not be used outside of `tracing` macros. ### Added - **attributes**: Support constant expressions as instrument field names ([#3158]) - Add `record_all!` macro for recording multiple values in one call ([#3227]) - **core**: Improve code generation at trace points significantly ([#3398]) ### Changed - `tracing-core`: updated to 0.1.35 ([#3414]) - `tracing-attributes`: updated to 0.1.31 ([#3417]) ### Fixed - Fix "name / parent" variant of `event!` ([#2983]) - Remove 'r#' prefix from raw identifiers in field names ([#3130]) - Fix perf regression when `release_max_level_*` not set ([#3373]) - Use imported instead of fully qualified path ([#3374]) - Make `valueset` macro sanitary ([#3382]) ### Documented - **core**: Add missing `dyn` keyword in `Visit` documentation code sample ([#3387]) [#2983]: https://github.com/tokio-rs/tracing/pull/#2983 [#3130]: https://github.com/tokio-rs/tracing/pull/#3130 [#3158]: https://github.com/tokio-rs/tracing/pull/#3158 [#3227]: https://github.com/tokio-rs/tracing/pull/#3227 [#3373]: https://github.com/tokio-rs/tracing/pull/#3373 [#3374]: https://github.com/tokio-rs/tracing/pull/#3374 [#3382]: https://github.com/tokio-rs/tracing/pull/#3382 [#3387]: https://github.com/tokio-rs/tracing/pull/#3387 [#3398]: https://github.com/tokio-rs/tracing/pull/#3398 [#3414]: https://github.com/tokio-rs/tracing/pull/#3414 [#3417]: https://github.com/tokio-rs/tracing/pull/#3417 [`Span::record_all`]: https://docs.rs/tracing/0.1.41/tracing/struct.Span.html#method.record_all
