5.0.8

• Fix: handle OPEN message with zero capabilities without crashing.
  Capabilities.unpack() read the parameter type byte before checking whether the Optional Parameters Length was zero, raising IndexError when a peer sent an OPEN with no optional parameters at all (a valid single 0x00 byte payload per RFC 4271). The early-return guard sat below the offending read so it never helped. Alternative to #1375.
