	 * In general, upgrade files between 4.1.5 and 500a1 are likely to be different in vB5 from their equivalent in vB4.
	 * Since large portions of vB4 code were removed in vB5, the upgrades to ensure that code works is unnecessary. If
	 * there are actual errors that affect vB5, those must be included of course. If there are changes whose absence would
	 * break a later step, those are required.
	 *
	 * But since these files will only be used to upgrade to versions after 5.0.0 alpha 1, most of the upgrade steps can be
	 * omitted. We could use skip_message(), but that takes up a redirect and, in the cli upgrade, a recursion. We would rather
	 * avoid those. So we have removed those steps,
	 * steps 1 and 2 the original are bad. Since a new install or upgrade from an early vB5 alpha install would not have this,
	 *	we would have different data properties in the wild.
	 * Steps 4,5,6 are not needed because vB4 mobile styles are not used in vB5, and wouldn't work anyway.
	 *
	 * Not certain about Step 4, so let's leave that in.
