Progress and Advancements of the Scala Codebase

The Scala language evolves continuously; we are open to suggestions on improvements and new features. Here is a summary of the past progress of the Scala system, and an introduction to the Scala Improvement Proposal Process, the process designed to allow users to present their own proposals for the improvement of the Scala language.

• Change Log
  The Change Log summarizes the evolution of the Scala language, since version 2.0. New language features, changes in the type system, and changes in syntax are all explained in clear terms.
   
• Version History
  The Version History contains a brief summary of the main bug fixes (with their Trac link) and code addition to the source code tree. The version history pages contain the full source version history since Scala Version 1.0.0-b2 (released on 2003/12/08).
   
• Scala Download Statistics
  If you would like to know exactly how frequently the Scala distribution is being downloaded, this page will show you the download statistics for the past month, showing you how many times each file has been downloaded.
   
• The Scala Improvement Proposal Process Guide
  In order to organize and make more systematic the process of requesting, and implementing new features in the Scala language, we have created the Scala Improvement Proposal (SIP) process, modeled after the equivalent Python process. By following the instructions in the SIP-00000, users can submit their own documents containing Scala language improvement proposals, as well as guidelines on further Scala-related processes, or just informational documents on relevant Scala design issues.
