Product updates for Azure Cosmos DB for PostgreSQL

APPLIES TO: Azure Cosmos DB for PostgreSQL (powered by the Citus database extension to PostgreSQL)

Release notes

Azure Cosmos DB for PostgreSQL gets updated regularly.

Updates that don’t directly affect the internals of a cluster are rolled out gradually to all supported regions. Once such an update is rolled out to a region, it's available immediately on all new and existing Azure Cosmos DB for PostgreSQL clusters in that region.

Updates that change cluster internals, such as installing a new minor PostgreSQL version, are delivered to existing clusters as part of the next scheduled maintenance event. Such updates are available immediately to newly created clusters.
