+## [3.10.0](https://github.com/elastio/bon/compare/v3.9.3...v3.10.0) - 2026-08-25
+
+### MSRV Update Notice
+
+This release raises the minimum supported Rust version from `1.59.0` to `1.88.0`. If you are on an older compiler, stay on `bon@3.9`.
+
+The new MSRV also comes with the deprecation of the `implied-bounds` cargo feature. Implied bounds are now added by default without any feature gate, so be sure to remove that feature from your `Cargo.toml` if you have it enabled. It's currently a no-op, and it won't be removed until a major release, for which there are no plans yet.
+
+The MSRV bump comes from the `darling@0.24` update, which is the first version that uses `syn@3.0`.
+
+### Added
+
+- Support the `default` switch in the [`on(...)`](https://bon-rs.com/reference/builder/top-level/on) clause ([#398](https://github.com/elastio/bon/pull/398)). Thanks [@ChrisJr404](https://github.com/ChrisJr404) for the contribution!
+
+### Changed
+
+- Bump MSRV to `1.88.0`, move to the 2024 edition, update to `syn@3.0` and `darling@0.24` ([#399](https://github.com/elastio/bon/pull/399))
+- Deprecate the `implied-bounds` cargo feature. Implied bounds are now generated by default ([#399](https://github.com/elastio/bon/pull/399))
+
+### Internal
+
+- Regular maintenance ([#392](https://github.com/elastio/bon/pull/392))
