v0.21.0

Breaking changes

• The max outgoing packet size is now 1452 bytes (based on Ethernet MTU), down from 8972 bytes, per RFC 6762 section 17. A record too big for one packet is still sent alone, in a packet of up to the RFC's 9000-byte ceiling, so no record is dropped. Users that need to change the limit can call the new ServiceDaemon::set_max_packet_size().

New features

• Add ServiceDaemon::set_max_packet_size() to change the max byte size of outgoing packets on the interfaces matching a given IfKind. (#487)
• Re-export the receiver-side error types RecvError, RecvTimeoutError and TryRecvError from flume, so that a caller can name them without adding flume as a direct dependency. (#488)

Bug fixes / improvements

• On the receive side, the IPv4 and IPv6 max packet sizes are now tracked separately (8972 and 8952 bytes) so that each stays within the RFC's 9000-byte limit including its own IP header. (#487)
