"Liferay DXP 7.0" was initially released as "Liferay DXP" but later rebranded with the version information in the name (as newer versions were released). This tag has started as being limited to "DXP 7.0", but has been used independent of the exact version (7.0, 7.1, 7.2) for a long time. The updated tag description acknowledges this by asking for the version to be tagged additionally.
