0.20 Development Cycle
Development of FreeCAD 0.20 began following the tagging of | FreeCAD's 0.19 release version on February 25, 2021.
Minimum supported library versions
Development of 0.20 targets Ubuntu 18.04 LTS as the oldest officially-supported OS for compiling FreeCAD. Minimum supported infrastructure software versions are:
- GCC 7.4
- Clang 6.0
- CMake 3.10
- Python 3.6
- Qt 5.9
- OpenCASCADE 7.3
This version of FreeCAD is compiled requiring the C++17 standard, and all C++17 features are allowed with two exceptions:
- std::filesystem is not well-supported by GCC 7.4 -- continue to use boost::filesystem instead
- std::regex is much slower than boost::regex in some important cases, so we will continue to include the Boost regex library
Developers are encouraged to review the C++ Core Guidelines for modern C++ coding advice. No strict coding convention has been selected for FreeCAD, though new C++ code often conforms to the Qt coding conventions, and new Python typically conforms to PEP 8.
Features Under Development
As volunteer-developed Open Source software it is impossible to guarantee that any particular feature will be implemented in a given time frame. Major features or modifications that developers are currently working on include:
- Developing solutions to the Topological naming problem
- Improving Spreadsheet usability and interoperability
- Improving OpenSCAD interoperability via the OpenSCAD Workbench: implementing missing functions and improving CSG shell generation in special cases
