Description

Developers often encounter difficulties debugging events-related issues due to insufficient or unclear documentation across different Open edX releases. This lack of detailed documentation makes it challenging to determine the existence and behavior of specific events in various platform versions.

Expected Result

• Comprehensive and clear documentation for events across all Open edX releases.
• Easy accessibility and searchability of event documentation to facilitate efficient debugging.
• Timely updates to documentation with each new release to reflect changes and additions accurately.

Possible Solutions

Release versioning documentation for events:

• Maintain detailed documentation that outlines the events available in each Open edX release.
• Ensure that the documentation includes descriptions, usage examples, and any relevant configuration details.
• Update the documentation promptly with each new release to ensure it accurately reflects the current state of the platform.
