This is a major update, which includes support for legacy browsers (IE < 9). It doesn’t affect existing users, because it doesn’t change the API or its semantics, but provides an option for legacy applications. It is considered “major” because it changes some internal plumbing.

legacy.js documentation contains all necessary background information for the change, and recommendations on how to use it in real projects.

Changes:

• Added metadata for an extended Dojo release.
• Internal code is better formatted, better documented, variables are renamed to use more suggestive names.
• Added legacy.js module, which is a substitute for mini.js in legacy environments.
