Some of the properties have changed names. Furthermore, some properties need to be collected as often as every 2 hours, whereas others only need to be collected once every other day. For most players (myself included), the properties with a collect time of less than 24 hours just lost a lot of value. Here is the property list:
Louie's Deli (can not be upgraded) - needs to be collected hourly.
Flophouse - needs to be collected every 8 hours.
Pawnshop - needs to be collected every 24 hours.
Tenement - needs to be collected every 48 hours.
Warehouse - needs to be collected every 12 hours.
Restaurant - needs to be collected every 2 hours.
Dockyard - needs to be collected every 8 hours.
Office Park - needs to be collected every 12 hours.
Uptown Hotel - needs to be collected every 24 hours.
Mega Casino - needs to be collected every 48 hours.

Undeveloped lots were automatically converted into cash for players; lots are no longer purchaseable.
Players also now upgrade their buildings rather than buy new ones. If you had 300 mega casinos prior to the update, you will now have a "Level 300 Mega Casino".
Overall, this appears to be a nerf as some properties need to be collected manually every few hours, whereas before, many people did not have to collect a take at all (myself included).
The real purpose behind this change (I hope) is to allow players to rob each other's high level properties for some big $ and also give property some unique features (hence the map that is "Coming Soon".
I'm looking forward to it, and will withhold further judgment until more information becomes available.
I also have no idea what will happen for people with rackets, and if those influence points will be refunded. Good luck!
That is an example of some the three boosts you can buy. You may notice that below it is an item called "Hobo Lookout" which provides +60 robbing skill. The more powerful boosts like this one are the result of turning in collection items. You can re-vault a collection to receive a number of boosts. This number appears to vary from collection to collection (but it not a random number). Feel free to post in the comments how many items each vault gives so I can post it up.
This is where the new interface comes in handy; things would get quite messy if your boost was listed somewhere in the wall of text of equipment in the old fighting interface.
The boosts can then be found in your inventory. There is a different set of boosts for each collection. Here is a complete list:
