Release notes:

What's Changed

Azure API for FHIR (Cosmos)

• (4.0.745) Fixing SessionMessageHandler to handle multiple session tokens by @v-isyamauchi-gh in https://github.com/microsoft/fhir-server/pull/5521
• Resolves test failures by updating SessionMessageHandler to handle multiple session tokens returned when Cosmos DB requests span multiple partitions.

Azure Health Data Services (SQL)

• (4.0.745) Disable local auth for the cosmos db (S360 item) by @v-rachitsh in https://github.com/microsoft/fhir-server/pull/5528
• Disables local authentication for Cosmos DB accounts in the PR provisioning pipeline to enhance security compliance.
• (4.0.745) Return 404 instead of 500 for unknown resource type for Sql by @mikaelweave in https://github.com/microsoft/fhir-server/pull/5513
• Previously, an unknown or mis-cased resource type in a query that reached the SQL data layer (for example, a case-mismatched DELETE /patient/{id} ) would result in a 500 Internal Server Error. This has been improved to a more informative 404 Not Found.

Common to both Azure API for FHIR and Azure Health Data Services

• (4.0.745) Atomic Search Param operations by @jestradaMS in https://github.com/microsoft/fhir-server/pull/5433
• Makes SearchParameter CRUD operations fully atomic and more reliable, removing partial commit risks and reducing lock contention in transaction bundles.
• (4.0.745) Add SQL Elastic Pool and tweak CI env vars by @jestradaMS in https://github.com/microsoft/fhir-server/pull/5522
• Adds SQL Elastic Pool support and optimizes CI environment variables for better infrastructure management.
• (4.0.745) Enhance input validation for export parameters by @mikaelweave in https://github.com/microsoft/fhir-server/pull/5535
• Adds validation to reject path traversal sequences in $export endpoint parameters to prevent unauthorized access to blob storage paths.

Other Changes

• (4.0.745) Single cache refresh from bundle by @SergeyGaluzo in https://github.com/microsoft/fhir-server/pull/5499
• Optimizes cache refreshing by performing single refresh from bundles instead of individual refreshes per operation.
• (4.0.747) Ensure PR pipeline runs E2E tests separately by @jestradaMS in https://github.com/microsoft/fhir-server/pull/5537
• Ensures PR pipeline runs Reindex and BulkUpdate tests as separate jobs for SQL to improve test reliability and isolation.
• (4.0.747) Fix ReindexTests by removing unnecessary search parameter cleanup by @jestradaMS in https://github.com/microsoft/fhir-server/pull/5543
• Removes unnecessary search parameter cleanup from ReindexTests to eliminate flakiness caused by search parameter collisions.
