Release Versions

A release version refers to a specific version of the CourseKata textbook that has been finalized and made available to students for use. Each release version represents a complete and stable iteration of the course material, with all the assignments and assessments that are intended for student use. To ensure the continuous improvement of the course content,there are 3-4 releases per year. Currently the release dates are March 1, July 1, December 1.

Purpose of Release Versions

The primary purpose of these updates is to implement improvements to the course material and correct any errors that may have been identified since the previous release. The updates included in each release are a culmination of extensive feedback (from students and instructors), data-based evaluation, and refinement processes. The purpose is to improve the learning experience for students by incorporating hundreds of minor improvements and, at times, major changes to the course content or structure. In this release version overview, you will find detailed documentation of the changes that have been implemented with each release.
