+dependencies, etc. The dependency graph quickly becomes overwhelming if you have to manually install each one. This is where package managers come
 in. Depending on what platform you are developing on, you have a variety of tools at your disposal to resolve these dependencies. A brief overview
 of the most common ones is included below. The main purpose of this document is to highlight the primary dependencies and describe what they do and
 why FreeCAD needs them.
 
 
 ## Supported versions
 
-The head of the main branch of FreeCAD, currently used for the development of FreeCAD 1.2, can be compiled from source on systems as old as the oldest currently-supported [Ubuntu LTS](https://packages.ubuntu.com/) at the time of its expected release, Ubuntu 24.04 LTS. This ties FreeCAD development to the C++23 standard, Python 3.11 and later (we plan to swtich to 3.12 or later once Blender updates their dependencies in mid-2026), Qt 6.4, and the versions of the required libraries available on that system. Note that Qt does not support PySide6 `pip` installation on this system, so use of a PPA is required for that dependency. The decision to stop support for Qt5 was [announced 5 January 2026](https://forum.freecad.org/viewtopic.php?t=102292).

 An alternative is to use Conda to create your Mac OS build system. Documentation of this process is a [work-in-progress by several users on the FreeCAD Forum](https://forum.freecad.org/viewtopic.php?t=70038).
