# Release20130715

This is an archived public release of MLton, version 20130715.

## Changes since the last public release

- Compiler.

  - Cosmetic improvements to type-error messages.

  - Removed features:

    - Bytecode codegen: The bytecode codegen had not seen significant use and it was not well understood by any of the active developers.

    - Support for .cm files as input: The ML Basis system provides much better infrastructure for "programming in the very large" than the (very) limited support for CM. The cm2mlb tool (available in the source distribution) can be used to convert CM projects to MLB projects, preserving the CM scoping of module identifiers.

  - Bug fixes: see changelog
