Late yesterday evening Valve announced that they're releasing a new treasure into the Dota 2 client. The new treasure is called "Treasure of the Carmine Cascade" and contains sets for AA, Batrider, Oracle, and more.

However, that's not all. Valve has also simplified the way escalating odds works. For those not aware what "escalating odds" means the short explanation is that every time you open a treasure, your chances of receiving one of the rare/very rare/extremely rare items increases. Previously the percentages were not shown, but that is changed after this update:
We’ve also taken this opportunity to simplify and rework the way we calculate escalating odds for this treasure and going forward. You can now click on the escalating odds arrow next to each of the rare, very rare, or extremely rare drops to see the exact odds of receiving them based on how many you’ve already opened.
The update also enables Dota Plus subscribers to recycle unwanted items from the treasure. You can read more about that on the official update page.
