1. Understanding Qt 5.15.2 & the “Offline Installer” Concept
1.1 What is Qt 5.15.2?
- Qt 5.15 is the last long-term-support (LTS) release in the Qt 5 series (originally supported until May 2021, extended for commercial licensees).
- 5.15.2 is the final public open-source bug-fix release (released November 2020).
- After 5.15.2, open-source users only get security fixes via the 5.15.x branch (some distros backport), but no official Qt binaries.
Pro tip: If disk space is limited, deselect Android, iOS, and obsolete web view modules.
