Release notes 1.0 - FreeCAD Documentation
As much as we're delighted to present you this new version, we are also sad to announce that our friend and prolific FreeCAD developer bgbsww has passed away a few weeks before this release came out. He was one of the main architects of the topological naming fixing effort, wrote a lot of additional code and tests, and became FreeCAD's TNP specialist. He also helped virtually all other developers out to adapt to the new algorithm. This release is dedicated to him.
Although precautions have been taken to guarantee that files created with the new 1.0 version can still be opened in older versions of FreeCAD, some new features introduced in 1.0 cannot be understood by earlier versions, and can cause models saved with 1.0 to break or present problems when opened in earlier versions of FreeCAD. Here is a summary of possible issues you might encounter and their solution. The forum community can also provide help in fixing compatibility issues.
