This post summarizes the second LTS release of Aurora MySQL version 3.
I hope this helps in some way.
 

v3 is the second LTS release

Amazon Aurora MySQL v3 (MySQL 8.0 compatible) will reach Long Term Support (LTS) on August 18, 2025 (US time).Version 3.10has been released.
LTS is a version that will provide stable support for a long period of time, making it an important option for systems where stability is important, such as production environments.
What's New at AWS - Cloud Innovation & News
Starting today, long-term support (LTS) will also be provided on Aurora MySQL 3.10 (compatible with MySQL 8.0.42) minor version. Database clusters that use LTS releases can stay on the same minor version for at least three years or until end of standard support for the major version, whichever is sooner. During the lifetime of an Aurora MySQL LTS release, new patches introduce fixes for select high severity security and operational issues. These patches don't include any new features. For more details about Aurora MySQL 3.10, refer to the Aurora MySQL 3.10 launch announcement and release notes. This is the second minor version designated as LTS on Aurora MySQL-Compatible Edition 3 in addition to Aurora MySQL 3.04 (compatible with MySQL 8.0.26) minor version. This LTS version does not change the end of life schedules for other LTS versions or engine major versions. For more details about LTS and how to stay on the LTS minor version, refer to LTS documentation. This LTS release is available in all AWS regions where Aurora MySQL is available. Amazon Aurora is designed for unparalleled high performance and availability at global scale with full MySQL and PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.

v3.10 (compatible with MySQL 8.0.42) itself was released on July 30, 2025, but was initially not an LTS, but rather had the usual one-year support period.
 
The standard support period for this LTS release of Aurora MySQL 3.10 is as follows:April 30, 2028This will make it easier to plan system operations from a long-term perspective.
 

The biggest improvement from the previous LTS (v3.04) is support for RDS Data API.

v3.04
v3.07
The RDS Data API is a web services interface that allows you to interact with your database through an HTTPS endpoint, enabling you to securely execute SQL from serverless applications like AWS Lambda without having to manage persistent database connections.
Benefits include secure access control in conjunction with IAM roles and simplified connection pooling.
 
AlsoAurora MCP ServerThis tool uses the RDS Data API internally, so it was not available in the previous LTS, v3.04.
Aurora MCP Server is a set of tools that streamlines database development, such as converting natural language queries into SQL and executing them.
I have written a blog post about Aurora MCP Server in the past, so please refer to that.
