Version Support Policy

The support for Kubernetes Ingress Controller software versions is explained in this topic.

Version support for Kong Ingress Controller (Enterprise)

Kong primarily follows semantic versioning (SemVer) with its products.

At Kong’s discretion a specific minor version can be marked as a LTS version. The LTS version is supported on a given distribution for the duration of the distribution’s lifecycle, or for 3 years from LTS release whichever comes sooner. LTS only receives security fixes or certain critical patches at the discretion of Kong. Kong guarantees that at any given time, there will be at least 1 active LTS Kong version.

LTS versions of Kubernetes Ingress Controller are supported for 3 years after release. Standard versions are supported for 1 year after release.

Bug fix guidelines

Unfortunately, all software is susceptible to bugs. Kong seeks to remedy bugs through a structured protocol as follows:

  • Serious security vulnerabilities are treated with the utmost priority. See here for our security vulnerability reporting and remedy process, including how to report a vulnerability.

  • Bugs which result in production outages or effective non-operation (such as catastrophic performance degradation) will be remedied through high priority bug fixes and provided in patch releases to the Latest Major/Minor Version Release of all currently supported Major Versions of the software and optionally ported to other versions at Kong’s discretion based on the severity and impact of the bug.

  • Bugs which prevent the upgrade of a supported version to a more recent supported version will be remedied through high priority bug fixes and provided in the Latest Major/Minor Version Release of all currently supported Major Versions of the software and optionally ported to other versions at Kong’s discretion based on the severity and impact of the bug.

  • Other bugs as well as feature requests will be assessed for severity and fixes or enhancements applied to versions at Kong’s discretion depending on the impact of the bug. Typically, these types of fixes and enhancements will only be applied to the most recent Minor Version in the most recent Major Version.

Customers with platinum or higher subscriptions may request fixes outside of the above and Kong will assess them at its sole discretion.
