The latest PyLibMc has changed the way in which booleans are stored from strings to integers to avoid conflicts in which python-memcached manages them. The end result? If you were noticing that your cache is returning ints instead of True/False, this change in PyLibMC cached this issue!

If you have API responses that are returning invalid values, you'll need to wrap the value in bool() to fix the issue!
