LibPack-1.1.0 Version 3.1.1.3

LibPack 3.1.1.3 is designed for use with the FreeCAD 1.1dev version and MSVC 143 compiling in Release or RelWithDebInfo modes (Debug mode is not supported). It is identical to 3.1.1.2 but adds the cxxstd=20 flag to the boost b2 build options. Changes from 3.1.0 are that all libraries are compiled with the C++20 standard enabled, and versions are updated as follows:

• boost 1.86.0 → 1.87.0
• harfbuzz 10.1.0 → 10.4.0

LibPack-1.1.0 Version 3.1.0

LibPack 3.1.0 is designed for use with the FreeCAD 1.1dev version and MSVC 143. The biggest change from the 3.0 series is the removal of boost-python and its replacement with pybind11. It also updates the versions of most libraries to their latest version (exceptions are that Python is held to the 3.12.x release because IfcOpenShell does not yet support Python 3.13, numpy, because pynastran does not support numpy 2, HDF5 uses 1.12.x because SALOME medfile requires that version, and ICU is held to version 74.2 because Xerces-C 3.2 cannot use later versions, and Xerces-C 3.3 does not compile under MSVC 143).

It provides:

• Qt 6.8.1
• OpenCASCADE 7.8.1 [FreeCAD-patched, see https://github.com/FreeCAD/OCCT]
• Python 3.12.7 with the following 3rd-party modules installed:

LibPack-1.0.0 Version 3.0.0

This LibPack release is designed to work with FreeCAD 1.0. It should be used with the MSVC 14.4 or later compiler toolchain (released mid-2024), in Release or RelWithDebInfo modes (not Debug mode, due to lack of debug numpy. We hope to address that shortcoming in a future release), on x86_64 architecture (ARM support is planned for the future). It requires at least FreeCAD 0.22dev commit hash 99d63a9693316bad118740dc8ee86098cca5e16b.

This release is identical to RC4 in all but final version number.

The 7-zip-compressed download has been manually stripped of QtWebEngine, various pieces of documentation, and several other executable files that are built by several of those tools. If you build it yourself it will be significantly larger than this download. Eventually this stripping will be coded into the build script, but that work is not complete.
