In 2017, Monotype Imaging released Arial, version 7.01, as an OpenType font, compatible with both Windows and macOS operating systems. This version included several improvements:

To the untrained eye, this appears to be a random collection of typographic jargon. To a digital forensics expert, a graphic designer, or a publishing technologist, however, it tells a complete story of the font’s origin, technical construction, encoding standard, regional adaptation, and intended use case.

While visually nearly identical to version 7.00, some graphics applications may flag a "missing font" or request confirmation when substituting 7.01 for 7.00 in legacy files.

This is where the keyword gets technically fascinating. At first glance, "OpenType TrueType" sounds contradictory. Aren’t OpenType and TrueType competing formats? The answer is more nuanced.
