v3.0.4

• fix: check against correct value for undefined in PROTO.Optional::serialize, previously used incorrect value variable, instead of optional, causing the serializer to always put a true value (value is the sub-type serializer that is passed into the Optional() helper function, which is always defined), and causing incorrect deserialization. 83f267e

• fix: isolate connection endpoints for DirectIPC. previously, both the manager and connections listened on the same endpoints, causing incorrect behaviour. 501a273

• fix: use correct char_size value when serializing bytes in the UTF8 range. 525cd0a
