Legacy Support

This version is incompatible with source code written for previous versions, including Jule 0.1.3. Older compiler versions cannot compile this version’s standard library and existing source code may need to be adapted for the new version.

The most common potential issues:

• Incompatibilities with the new error handling standard
• Using dynamic types
• Renaming and reimplementations on the standard library
• Unexpected behavior in range iterations with strings
