	/** 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,
	 * step 1 in the original is not needed because we don't use the navigation table in vB5
	 * step 2- Not needed, this was part of the changes for sending mail by vb cron, this functionality wont currently exist in vb5
	 * Step 3- We don't use the user.newrepcount field in vB5.
	 * Step 4- we never query anything sorted by user.lastactivity or join on it.
	 * Step 5- we don't use the contentread table in vB5
	 * Step 6- we don't use the ipdate table in vB5
	 * Step 7- Not needed, all products are zapped by vB5 anyway.
	 * Step 8- We don't use the block table
	 * Step 9- Not needed, this was for double post prevention added in 4.2, it doesnt exist in vb5.
	 * Step 10- We don't use the forum table
	 * Step 12- We don't use the activitystreamtype table
	 *  Step 13, 14 - We don't use the activitystream table. We have a similar concept in vB5 but handled differently
	 *  Step 15, 16- Since we don't use activitystream we don't need the phrase group or type
	 *  Step 17, 18, 19- We don't use the picturecomment table. The hierarchy is handled completely differently in vB5
	 *  Step 20- We don't use the thread table
	 *  Step 21- We don't use activitystream approach
	 *  Step 22- this inserts a cron job to keep the activitystream up to date- but we don't use that approach.
	 *
	 * So we have some use for step 11
