When will Elasticache support Valkey 8.0.2?

According to the most recent information available, Amazon ElastiCache currently supports Valkey version 8.0, not 8.0.1 as you mentioned. There is no mention of a Valkey 8.0.2 version in the provided documentation.

The latest version of Valkey supported by ElastiCache is 8.0, which was announced on November 21, 2024. This version brings faster scaling and improved memory efficiency. Some of the new features in Valkey 8.0 include:

1. Memory efficiency improvements, allowing users to store up to 20% more data per node without any application changes.
2. A newly-introduced per-slot metrics infrastructure for self-designed caches, providing detailed visibility into the performance and resource usage of individual slots.
3. For ElastiCache Serverless with Valkey 8.0, the ability to double the supported requests per second (RPS) every 2-3 minutes, reaching 5M RPS per cache from zero in under 13 minutes, with consistent sub-millisecond p50 read latency.

Amazon ElastiCache typically doesn't provide specific release schedules for future versions. The service aims to offer the latest stable versions of supported engines, but the exact timing of updates can vary. If there are critical updates or security patches, ElastiCache reserves the right to patch clusters on behalf of users.

For the most up-to-date information on supported versions and upcoming releases, it's best to regularly check the official AWS documentation or announcements.
