I hope this is of some help.
 

v3 is the second LTS release.

August 18, 2025 (US time): Amazon Aurora MySQL v3 (MySQL 8.0 compatible) LTS (Long Term Support)Version 3.10It has been released.
LTS versions offer stable support over an extended period, making them an important choice, especially for systems where stability is paramount, 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.

Although v3.10 (compatible with MySQL 8.0.42) was released on July 30, 2025, it initially had a standard one-year support period, not an LTS (Long-Term Support) release.
 
The standard support period for Aurora MySQL 3.10, which is being released as an LTS (Long-Term Support) version, isApril 30, 2028It is planned to be provided until [date], making it easier to create a long-term system operation plan.
 

A major improvement over the previous LTS (v3.04) is support for the RDS Data API.

v3.04
v3.07
The RDS Data API is a web service interface that allows you to interact with databases via HTTPS endpoints. This enables secure SQL execution from serverless applications such as AWS Lambda without having to manage persistent database connections.
This offers benefits such as secure access control in conjunction with IAM roles and simplified connection pooling.
 
AlsoAurora MCP ServerConvenient tools like this will become available. This tool uses the RDS Data API internally, so it was not available in the previous LTS version, v3.04.
Aurora MCP Server is a suite of tools that streamlines database development, including translating natural language queries into SQL for execution.
I've written a blog post about Aurora MCP Server in the past, so please refer to that.
