• Upgraded the Cosmos DB library to fix a security issue. CVE-2025-55163 (#3105)
• Fixed an inconsistency where Get and Scan operations were prepared differently for transaction reads and Serializable validation, which could result in inconsistent ordering and cause Serializable validation failures. (#3113)
• Deprecated --log-success argument and introduced a new replacement option --enable-log-success (#3117)
• Fixed incorrect validation causing maxThreads to be treated as required (#3128)
