How this is compiled. Each edition is assembled from official vendor release notes, changelogs, and corporate newsrooms, with AI assistance for the first-pass scan, then reviewed and edited by me before publishing. Items are checked against the primary source; anything I could not confirm is flagged inline.

Corrections and method notes. Found something inaccurate or out of date? Tell me and I will fix it in the next edition.
