Source hierarchy
We prioritize sources closest to a product’s release and development:
- Official product pages, manuals, release notes, and dated announcements.
- Archived official pages when a product is no longer maintained.
- Reliable contemporary reporting, reviews, and specialist historical archives.
Images and screenshots
Interface images are displayed with a source link and attribution. We use official product images when available; for discontinued software, we may use an identified archival source. Copyright remains with the respective rights holder. If you own an image and want its use corrected or removed, submit a note with the relevant details.
Uncertainty is information
Where a precise date, format, or feature cannot be verified, we avoid inventing it. Records may use a year rather than a full date, describe a source as archival, or mark a field as not yet documented.
