Today I saw three examples (below) of old questions edited for the reason "Removed arcgis-9.2 tag because it is a Retired version". In each example, the ArcGIS 9.2 tag was germane to the question; the author identified that version in the question or follow-up comments.
- Performance issues after upgrading from 9.2 to ArcGIS Mobile release 10
- Connect overlapping lines?
This situation is sure to occur in the future. As ArcGIS, QGIS, and other software (with version-specific tags on GIS SE) continue to release new versions, there will still be questions related to those old versions. Should the tags for these old question be revised?
I think this is similar to the meta discussion in Should old questions be updated to reflect details of later questions that were closed as duplicate?
