4.15.0 (2026-02-19)

Features Added

• GA support of Per Partition Automatic Failover and AvailabilityStrategy features.

Bugs Fixed

• Fixed bug where sdk was encountering a timeout issue caused by infinite recursion during the 410 (Gone) error. See PR 44770
• Fixed crash in sync and async clients when force_refresh_on_startup was set to None, which could surface as AttributeError: 'NoneType' object has no attribute '_WritableLocations' during region discovery when database_account was None. See PR 44987
• Fixed bug where unavailable regional endpoints were dropped from the routing list instead of being kept as fallback options. See PR 45200

Other Changes

• Added tests for multi-language support for full text search. See PR 44254
• Renamed availability_strategy_config introduced in 4.15.0b1 to availability_strategy for both sync and async clients. See PR 45086.
• Request-level availability_strategy needs to be set to False in order to disable availability strategy for that request, as opposed to setting it to None. See PR 45141.
