Portainer makes this policy public so customers and partners can effectively plan, deploy, and support their container management infrastructure effectively using Portainer. It is published in an effort to provide as much transparency as possible but Portainer has the discretion to make exceptions from this policy should that be in Portainer’s or our customer’s best interests.
Any release dates are provided for guidance only and the exact dates may change.
Portainer releases approximately follow a monthly cadence for minor releases (X.Y) which can introduce feature enhancements and new features but endeavor to maintain backward compatibility.
Micro or patch releases (X.Y.z) are released as needed and are limited to backward compatible bug fixes only.
Major versions (X) will be much less frequent, will include potential breaking changes, and may require an upgrade or migration process from previous versions.
All releases are cumulative - all previous enhancements and fixes are included in each release.
When we say “supported”, we are referring to the commercial support that is included with Portainer Business Edition subscriptions at the Scale and Enterprise level. This includes access to all STS and LTS releases and patches. Our have more detail on what is and isn’t covered by our support.
For Starter, Home & Student, our free Business Edition offerings, and our Community Edition, support is provided through our .
The term “maintained” refers to the act of releasing updated versions of our releases, for example patches to resolve bugs or security issues. All editions of Business Edition and Community Edition will be maintained according to each release’s respective lifecycle.
Portainer always recommends updating to the latest version in the release stream to ensure you have the latest security fixes, bug fixes, and performance improvements. It is at Portainer’s discretion to backport fixes to any version outside of the supported version window.
Portainer has two release streams, STS and LTS and it’s important you know the differences so you can choose accordingly.
Short Term Support releases are identified with an “STS” suffix.
These are supported and maintained until the release of the next STS or LTS version. Use STS versions if you are interested in getting the latest features faster and don’t mind upgrading more frequently.
Long Term Support releases are identified with an “LTS” suffix.
These releases are supported and maintained until the release of the next LTS version plus a three month migration window so are more suitable for environments where adding new features on a frequent basis is less desirable.
Each stream (LTS and STS) will have a number of patch releases throughout it’s life.

Sitting on an older release that is no longer maintained or supported is strongly discouraged and customers take full responsibility for doing so. Customers are strongly encouraged to ensure they are running the latest patch release for a given stream.
