+## [0.7.0] — 2026-06-20
+
+### Added
+
+- **Multi-targeting `net8.0` and `net10.0`.** The package now ships assemblies for
+  both `net8.0` (current LTS) and `net10.0`, so consumers no longer need the newest
+  runtime to take a dependency. All dependencies already provide `net8.0` assets, so
+  the dependency graph is unchanged. The only source adjustment was swapping the
+  `net9.0+` `System.Threading.Lock` used to guard libsecret symbol resolution for a
+  plain `object` lock; behaviour is identical. No public API change.
