When will Amazon Aurora MySQL support MySQL 8.4 compatibility?

Based on the available information, there is no publicly announced timeline for MySQL 8.4 support in Amazon Aurora MySQL. The current Aurora MySQL version 3 supports MySQL 8.0 compatibility, with the latest release (Aurora MySQL 3.09) supporting MySQL 8.0.40.

What we know:

• Aurora MySQL-Compatible Edition currently supports MySQL 8.0 and has its own release calendar
• Aurora MySQL will continue to support MySQL 8.0 without requiring extended support at least until April 30, 2028
• Amazon RDS for MySQL 8.4 is indeed already available, but Aurora MySQL follows a different release schedule

The extended MySQL 8.0 support timeline for Aurora MySQL (through at least April 2028) suggests that AWS is providing customers with a longer runway before requiring an upgrade to MySQL 8.4. However, this does not indicate when MySQL 8.4 compatibility will be introduced to Aurora MySQL.

Unfortunately, AWS does not publicly share specific roadmaps or timelines for future Aurora MySQL version releases. There is no mention in the available documentation of:

• A planned Aurora MySQL version 4 with MySQL 8.4 compatibility
• Beta or preview programs for MySQL 8.4 support
• Estimated release dates

For the most current information about future Aurora MySQL releases and to express your specific business need for MySQL 8.4 support, I recommend:

• Contacting AWS Support directly through your support plan
• Working with your AWS account team or Technical Account Manager if you have one
• Monitoring the Aurora MySQL release notes and AWS Database Blog for announcements

Your feedback about blocking dependencies on MySQL 8.4 features would be valuable input for AWS product teams to consider in their planning.

Short answer: No public timeline exists. AWS has not announced MySQL 8.4 support for Aurora MySQL.

What we know:

• Aurora MySQL 3.x is based on MySQL 8.0 (currently up to 8.0.44 compatibility in Aurora 3.12.0)
• RDS for MySQL 8.4 went GA in late 2025
• Historically, Aurora lags RDS by 12-18 months for major version support (Aurora MySQL 3.0 with 8.0 support came ~18 months after RDS MySQL 8.0 GA)
• There is no public preview or beta program announced for Aurora MySQL 8.4

What this likely means for timeline:

• If the historical pattern holds: mid-to-late 2027 at the earliest
• Aurora versions require significant re-engineering (distributed storage layer, parallel query, Global Database compatibility) — it's not a simple rebase on upstream MySQL
• MySQL 8.4 is an LTS release, so AWS will likely support it eventually, but "when" is genuinely unknown

What you can do:

1. Check the AWS Database Blog — Aurora version announcements always appear here first
2. Submit a feature request through your AWS account's Support Center or through your TAM/SA if you have one — volume of requests influences prioritization
3. Evaluate RDS MySQL 8.4 as an alternative if your blocking dependency is urgent and you don't strictly need Aurora-specific features (multi-AZ with readable standby, Global Database, Serverless v2 scale-to-zero)
4. Check if your 8.4 dependency is actually 8.4-exclusive — many features people associate with 8.4 (like VECTOR type) are actually not in MySQL 8.4 community. What specific 8.4 feature do you need? It might already be available in Aurora 3.x or achievable via a workaround.

If this is truly blocking:

Contact your AWS account team directly. They may have visibility into internal timelines and can provide a more specific answer about when to expect Aurora MySQL 8.4 support.
