     - Fixed challenge authentication to cache challenge scopes only after challenge resource verification succeeds, preventing
     rejected challenges from being reused by later requests.
+- Name: azure_data_cosmos
+  Version: 1.1.0-beta.1
+  DisplayName: Cosmos DB
+  ServiceName: Cosmos DB
+  VersionType: Beta
+  Hidden: false
+  ChangelogUrl: https://github.com/Azure/azure-sdk-for-rust/tree/azure_data_cosmos@1.1.0-beta.1/sdk/cosmos/azure_data_cosmos/CHANGELOG.md
+  ChangelogContent: |-
+    #### Features Added
+
+    - Added `OperationOptions::utf8_decoding_mode` for opt-in lossy recovery of invalid UTF-8 in response JSON strings. ([#5367](https://github.com/Azure/azure-sdk-for-rust/issues/5367))
+
+    #### Bugs Fixed
+
+    - Keep CPU sampling active for long-lived clients and preserve diagnostics through partition split recovery, including `500/20206` errors. ([#5416](https://github.com/Azure/azure-sdk-for-rust/pull/5416))
+- Name: azure_data_cosmos_driver
+  Version: 1.1.0-beta.1
+  DisplayName: Cosmos DB Client Driver
+  ServiceName: Cosmos DB
+  VersionType: Beta
+  Hidden: false
+  ChangelogUrl: https://github.com/Azure/azure-sdk-for-rust/tree/azure_data_cosmos_driver@1.1.0-beta.1/sdk/cosmos/azure_data_cosmos_driver/CHANGELOG.md
+  ChangelogContent: |-
+    #### Features Added
+
+    - Single-partition queries are now eligible for cross-region hedging, bounding tail latency on a degraded region at the cost of a second request on pages that exceed the hedge threshold. Cross-partition queries are not yet hedged. ([#5452](https://github.com/Azure/azure-sdk-for-rust/pull/5452))
+    - Added layered `OperationOptions::utf8_decoding_mode` for opt-in lossy recovery of invalid UTF-8 in response JSON strings, with strict decoding by default and a recovery indicator in `DiagnosticsContext`. ([#5367](https://github.com/Azure/azure-sdk-for-rust/issues/5367))
+
+    #### Bugs Fixed
+
+    - Route the retry after a failed cross-region hedge race that observed `404/1002` to the write region on single-write accounts, instead of another read region that rejects the hub-only request with `403/3`. ([#5466](https://github.com/Azure/azure-sdk-for-rust/pull/5466))
+    - Cache the partition's hub region when a hedged read that sent the hub-only header succeeds, so later hub-only reads of that partition skip hub discovery. ([#5466](https://github.com/Azure/azure-sdk-for-rust/pull/5466))
+    - Avoid unnecessary routing-state copies for hedge feedback and unchanged partition transitions, and skip hedge feedback when the effective partition circuit breaker is disabled without disabling transport hedging. ([#5438](https://github.com/Azure/azure-sdk-for-rust/pull/5438))
+    - Share immutable partition routing state across snapshot refreshes instead of copying its maps, while preserving older snapshots for active readers. ([#5438](https://github.com/Azure/azure-sdk-for-rust/pull/5438))
+    - Avoid loading partition topology for lazy-mode logical-key operations unless partition-level failover or Gateway 2.0 session-token scoping requires it. ([#5431](https://github.com/Azure/azure-sdk-for-rust/pull/5431))
+    - Keep CPU sampling active while runtime or diagnostics handles remain alive. ([#5416](https://github.com/Azure/azure-sdk-for-rust/pull/5416))
+    - Preserve bounded diagnostic history through partition split recovery, query buffering, and terminal `500/20206` errors. ([#5416](https://github.com/Azure/azure-sdk-for-rust/pull/5416))
