3.0.6

feat(admin): "+ Create new" in the form header; the form foot keeps only submit (3.0.6)

News categories and articles: while editing, the head of the form shows the
shared x-gp247::form-new-button to return to an empty form (the list keeps
its page); the Cancel / Reset button at the foot is gone. The button ships
with GP247 Core 3.10, so requireCore is now 3.10; requireUpdateFrom becomes
minUpdateFrom.
