Moodle development has always been active. In recent years the changes has resulted in improved end users and teachers experience. Administration process and interface has also improved a lot.
We see most of the major upgrade from version 1.9 to 2.0. Most of these changes has been improved and refined over time up to 2.2. We continue to observer the same improvement process to continue for the upcoming release of 2.3 with few new features.
New Moodle promises for easier management for teachers, better user experience for student and many performance enhancements and additional integration for administrators. The product looks more promising and stable for large deployment in education and business use.
