+## [Unreleased]
+
+### Changed
+* BREAKING: the package targets `net10.0` only and no longer supports `net8.0`, which makes this a major release
+* `Microsoft.Azure.Cosmos` updated from 3.60.0 to 3.62.0, which becomes the minimum version for consumers. Its release notes list a breaking change of their own: thin client mode is enabled by default and does not support resource-token authentication (opt out with `AZURE_COSMOS_THIN_CLIENT_ENABLED=false`)
+
 ## [1.2.0] - 2026-10-01
 
 ### Added
