Rumor has it:

- [B]HOLY SHIT IT'S EOTL:[/B] there's a new community crate added to the item schema. Have an xPaw link (which also has its image): [url]http://www.reddit.com/r/tf2/comments/2m81k4/tf2_update_for_111314/cm1skpq[/url]

- Marlamin provides a close-up of the insides (potatoes? [B]BONUS[/B] ducks?): http://facepunch.com/showthread.php?t=1436952&p=46483047&viewfull=1#post46483047

- Bonus item schema link (which is where the EOTL crate image comes from), which also includes a name and description change, as well as some release date modifications: https://github.com/SteamDatabase/SteamTracking/commit/e8d597d99a88c6f12ae97d048855ae45ef142c8a

- See or come across an exploit? Say something (directly to Valve)! Instead of abusing exploits for yourself, get them fixed in a responsible manner. Head to http://www.valvesoftware.com/email.php and select the TF Team entry. Be sure to provide reproduction steps as well (but don't disclose them in public until after things are fixed).
