+ o Major features (circuit padding):
+ - Implement preliminary support for the circuit padding portion of
+ Proposal 254. The implementation supports Adaptive Padding (aka
+ WTF-PAD) state machines for use between experimental clients and
+ relays. Support is also provided for APE-style state machines that
+ use probability distributions instead of histograms to specify
+ inter-packet delay. At the moment, Tor does not provide any padding
+ state machines that are used in normal operation -- this feature
+ exists solely for experimentation in this release. Closes
+ ticket 28142.
