FEBio4 is a major upgrade from FEBio3. Although it will continue to read most older files (version 3, 2.5, 2), a new format (version 4) is the preferred format. Files can be converted with FEBio Studio 2. Most of the important changes in this update are under the hood and improved the consistency between the internal representation of the febio model, the input file format, and the model representation in febio studio 2. The changes facilitated the direct integration of febio into febio studio. See the release notes of febio studio 2 for additional information regarding this integration.
