Via the CS:GO blog:

MISC

• When inspecting in game items from user’s own inventory, from other users’ inventories, and from Community Market, players can now see an official Item Certificate that includes Finish Style, Finish Catalog Number, Pattern Template, and Wear Rating.
• Adjusted the nearby lobbies search algorithm, in addition to geographic proximity by distance, to include more results from the same country as the searching user, providing more relevant results for players living near borders.

Rumor has it:

• Here's an example of an item certificate: http://i.imgur.com/xTQ6sWD.png

  • You can view them by inspecting items, and then hovering over the icon in the lower right corner
  • This is a solution meant to replace API functions that you may remember being discontinued last week due to excessive load that couldn't be solved anytime soon

• Despite the larger than usual size, GameTracking is surprisingly light: https://github.com/SteamDatabase/GameTracking-CSGO/commit/27dc8fdcdf66587665eab8cfef53f07b3d298eea

• Most of the large size is from more shader updates (in \platform\shaders\fxc\), lightmappedgeneric_ps30.vcs on its own accounts for most of the size, clocking in at ~240 MB

• Size is ~310 MB
