We agreed with the manuals team that we could use the date shown on page 2 in the manual (currently “Dorico_3.0.0_en-US_2019-12-06”) to refer to the “documentation’s last-change” date, as for Dorico this was/is changing fairly frequently. It might be worth me bringing this up again and seeing whether it would be useful to have two dates - the date of the app’s release, and the date of the last revision to the documentation, so I’ll do that.
