Economy

The quality of the item drops you are eligible for is now tied to your Dota profile level. You can see your current drop level in your profile page
A quick-search bar has been added to the armory
Filters can now be created for the armory. These filters are stored in the Steam Cloud so that every machine you use will know your armory filter settings
An armory page now contains 60 items instead of 64. Armory sizes have been increased upwards slightly to account for this adjustment
Many items have been removed from the store. These can now be sold and bought on the Steam Community Market! Workshop contributors will receive a share of each resale of their items. The items that have been removed are not immortal: they may return to the store in future sales or events, or they may appear in the drop list from time to time
The item drop list has been greatly pared down and will now change over time. As new items are introduced old items will be removed (and will be accessible on the Steam Community Market). This should help keep the item drop list interesting over time
