Releases follow Semantic Versioning. There is a new minor release approximately every six months, which is supported with bug and security fixes until the next minor release.
From Qt 6.8 onwards, every 4th minor release is designated as a Long-Term Support (LTS) release, issued every 2 years and maintained for 5 years exclusively for commercial license holders. Open-source (Community Edition) users do not receive LTS benefits and are expected to update to every new minor release approximately every 6 months. For versions prior to Qt 6.8, LTS releases were supported for 3 years under commercial licenses.
Extended support beyond EOL is available as a commercial offering from The Qt Company.
The KDE Project maintains a patch collection to support Qt 5.15 LTS for open-source users. Moreover, the code of commercial releases is made open within 12 months and some level of security support still seems to continue in the form of code patches. This does not reflect in the table above as we only track official releases from https://www.qt.io.
More information is available on the Qt website.
You should be running one of the supported release numbers listed above in the rightmost column.
