Added support for creating Global Secondary Index (GSI) containers via CosmosContainerProperties.setGlobalSecondaryIndexDefinition() / getGlobalSecondaryIndexDefinition(), the new CosmosGlobalSecondaryIndexDefinition model, and the CosmosGlobalSecondaryIndexBuildStatus enum returned by getStatus(). - See PR 48480
Promoted the Full Fidelity Change Feed (AllVersionsAndDeletes) APIs to GA - See PR 49283
Enabled ReadConsistencyStrategy for Gateway V1 (compute gateway) and Gateway V2 (thin client proxy). Previously only supported in Direct mode. - See PR 48787

Fixed region name normalization for preferred and excluded regions — non-canonical inputs (e.g., "westus3", "WEST US 3") are now mapped to the canonical form. Also fixed a case-sensitive exclude-region check in PPCB reevaluate logic. - See PR 49090
Fixed UnsupportedOperationException when using readManyByPartitionKeys for empty pages. - See PR 49311
Fixed silent drift in CosmosChangeFeedRequestOptions when resuming from a continuation token via byPage(savedContinuation). Previously only maxPrefetchPageCount and throughputControlGroupName were inherited onto the rebuilt impl; endLSN, customSerializer, excludeRegions, readConsistencyStrategy, completeAfterAllCurrentChangesRetrieved, and other caller-supplied configuration were silently dropped. All non-token-encoded fields are now propagated. - See PR 49276

Added HTTP/2 PING keepalive (default ON) for Gateway service endpoints to detect silently-broken connections. - See PR 49095
Replaced per-client Schedulers.newSingle() schedulers in GlobalEndpointManager and GlobalPartitionEndpointManagerForPerPartitionCircuitBreaker with shared BoundedElastic schedulers in CosmosSchedulers to prevent thread count from scaling linearly with client/tenant count. - See PR 49062
Promoted the ReadConsistencyStrategy and Http2ConnectionConfig related @Beta APIs to GA. - See PR 49345
Fixed a sporadic NullPointerException in JsonSerializable.getWithMapping triggered by concurrent first-time calls to DatabaseAccount.getConsistencyPolicy() and its sibling lazy getters (getReplicationPolicy, getSystemReplicationPolicy, getQueryEngineConfiguration). The fix makes JsonSerializable.propertyBag final, closing an unsafe-publication race in the lazy-initialisation pattern. - See Issue 49256 and PR #49258
Changed 449 (Retry With) retries in Gateway V1 and Gateway V2 to be consistently orchestrated client-side. - See PR 49332
Added client-side fast-fail validation for ReadConsistencyStrategy.GLOBAL_STRONG: requests that specify GLOBAL_STRONG against an account whose default consistency is not STRONG are now rejected client-side with a BadRequestException (HTTP 400). - See PR 48787
