Release highlights

Cosmos DB 4.79.0

The Java Cosmos DB library includes a critical security fix for a Remote Code Execution (RCE) vulnerability (CWE-502). Java deserialization was replaced with JSON-based serialization in CosmosClientMetadataCachesSnapshot, AsyncCache, and DocumentCollection, eliminating the entire class of Java deserialization attacks. This release also adds support for N-Region synchronous commit, a Query Advisor feature, and CosmosFullTextScoreScope for controlling BM25 statistics scope in hybrid search queries.

AI Foundry 2.0.0

The Azure.AI.Projects NuGet package ships its 2.0.0 stable release with significant architectural changes. Evaluations and memory operations moved to separate Azure.AI.Projects.Evaluation and Azure.AI.Projects.Memory namespaces. Many types were renamed for consistency, including Insights → ProjectInsights, Schedules → ProjectSchedules, Evaluators → ProjectEvaluators, and Trigger → ScheduleTrigger. Boolean properties now follow the Is* naming convention, and several internal types were made internal.

AI Agents 2.0.0

The Java Azure AI Agents library reaches general availability with version 2.0.0. This release includes breaking changes to improve API consistency:

• Several enum types were converted from standard Java enum to ExpandableStringEnum-based classes.
• *Param model classes were renamed to *Parameter.
• MCPToolConnectorId now uses consistent casing as McpToolConnectorId.
• A new convenience overload for beginUpdateMemories was added.
