A quite significant update was released today that includes a new unlockable character (a robot) and plenty other new gameplay features.

Food spoils over long periods of time. Stale and Spoiled foods are less beneficial. Rotten food is practically inedible, but can be used as fuel or fertilizer.
Crock pot foods are now stackable.
You can build a Ice Box now to mitigate spoilage.
New unlockable character: WX78, a robot who can eat spoiled food with no penalties, and who hates all living things.
Steam cloud can now be disabled. (details below)
New camera controls for streamers/YouTubers: CTRL+P will freeze the camera in place. CTRL+H will hide the hud.
Smallbirds now grow up to become angsty Teenbirds. Teenbirds will grow up to be Tallbirds and leave the player.
The mysterious Otto Von Chesterfield can be found in some swamps. (You will need to start a new map to find him)
Beefalo travel in proper herds now. Herds regenerate off-screen (currently with adults)
Beefalo herds become agitated when they go into heat, and will chase away the player if they are not wearing a beefalo hat.
Beefalo sometimes drop a beefalo horn, which can be used to move beefalos around.
The Spider Hat is no longer craftable - you just wear the Spider Queen's head directly. It also can't be used to steal spiders from an existing queen.

Health and Hunger values have been re-tuned across the board. Characters have a larger hunger buffer now.
Addressed minor spelling mistakes
Minor tweaks and fixes
Fixed various save/load issues

Some people have reported save/load issues with Steam Cloud. We have added a workaround that will cause the game to save its files in your documents directory instead. To activate this mode, add the following two lines to your "C:\Program Files (x86)\Steam\steamapps\common\dont_starve\settings.ini" file:
