Perhaps we need to clarify that the supported versions is based on the version of Emacs which was stable at the time of release of the org version. For example, org 9.5, being released this week, means it would support Eamcs 27.x, 26.x and 25.x, but not Emacs 24.x. If Emacs 28 is released next month, this would not alter the supported versions as 9.5 was released before Emacs 28. When org 9.6 is released, the supported versions would be updated to include whatever version of Emacs is stable at that point (likely 28.x) and the two previous versions.=20
