MotherDuck Version Lifecycle Schedules
MotherDuck supports DuckDB versions according to a predictable lifecycle so you always know which version is safe to use.
The lifecycle schedules below form a part of MotherDuck’s Support Policies. They include Major Releases and Minor Releases to support DuckDB and DuckLake versions and specify end of life dates for both.
Currently Supported Versions
MotherDuck currently supports DuckDB 1.4.2.
- In US East (N. Virginia) -
us-east-1, MotherDuck is compatible with client versions 1.2.0 through 1.4.2. - In Europe (Frankfurt) -
eu-central-1, MotherDuck is compatible with client versions 1.4.1 through 1.4.2.
MotherDuck strives to support current DuckDB minor versions in alignment with the DuckDB and DuckLake release calendars.
We recommend that users run the latest minor version when possible to take advantage of the most up-to-date features and functionality.

End of Life (EoL) Policy
When a new minor version becomes available, the previous one enters Extended Support. While we don't offer support for new features, critical fixes may still be backported for the greater of:
- 6 months after the version’s release, or
- 4 months after the next minor version is released
When a minor version reaches its End of Life (EoL):
- Connections using that DuckDB version are blocked, requiring MotherDuck users to upgrade
- Ahead of scheduled End of Life (EoL) dates, MotherDuck provides in-app UI warnings, email communications, and targeted outreach to users about impacted versions slated for deprecation
MotherDuck Extended Lifecycle Support Add-On
MotherDuck offers an Extended Lifecycle Support Add-On to provide customers with peace of mind and flexibility to upgrade at a later date by extending ongoing technical support for a minor DuckDB version after it reaches its End of Life (EOL) date.
