Full Changelog: https://github.com/cantools/cantools/compare/39.0.0...39.1.0

Beware! This is a major release! It contains at least the following API changes:

• The initial attribute of Signal objects now always holds the initial signal value as a scaled quantity, unifying its semantics with that of Signal.minimum and Signal.maximum. Previously, initial used raw values for databases loaded from DBC files, while using scaled ones for databases loaded from ARXML. (The loaders for other file formats do not currently set the initial attribute.)
• The machinery for storing decimal numbers without rounding errors (*.decimal attributes) has been removed. In its place small rounding errors in load-store-load cycles are now accepted. To remediate this, the resulting database objects can now be compared approximately using the Database.is_similar() method.
