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.
Some releases are designated as Long Term Support (LTS) releases. Those are supported for three years but only for commercial license holders. For open source users, they are same as regular releases.
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.
