There are 2 version fields in Tracker:
- Affects version - this is the version of Moodle where the bug was first spotted. The person logging the bug enters it (normally only 1 version).
- Fix version - this is the version of Moodle that the bug was fixed in. It is completed by the developer when the bug has been resolved. Only one version needs to be specified because Moodle releases are cumulative.
- person logging the bug never specifies "fix version" because they don't make decisions on what's fixed when.
- Fixed version must be higher than affects version (unless the bug was found in the development version).
- A filter where status=resolved AND fixed version=x will show a complete list of bugs fixed for version x.
