+#### Redis Flex revamped engine
+
+Redis Flex is getting a revamped engine. With performance improvements, increased stability, and removing previous limitations around RAM utilization.
+
+Redis Flex now offloads also the least used keys with their values, allowing more hot data to be stored in RAM. This increases performance for most real world use cases.
+
+Past limitations requiring minimum RAM allocation to store all the database's keys are no more relevant. Allowing more flexibility and higher resource utilization.
+
+- Databases with Redis version 8.2 and later (newly created or upgraded to those versions) automatically use the new Redis Flex engine.
+
+- Databases with Redis version 7.4 and earlier will continue to run on previous engine.

-#### Redis Flex GA
-
-Redis Flex (Redis on Flash version 2) is now generally available for flash-enabled databases. Redis Flex is the enhanced successor to Auto Tiering (Redis on Flash version 1), which allows you to provision larger databases at a lower cost by extending the RAM with flash drives.
-
-- Databases created with Redis version 8.0 and later automatically use Redis Flex.
-
-- Databases with Redis version 7.4 can choose between Auto Tiering (`bigstore_version` 1) and Redis Flex (`bigstore_version` 2)
-
-- Databases with Redis versions earlier than 7.4 will continue to use Auto Tiering.
