## [0.4.6] - 2022-10-25
### Added
- Support for prioritising multiple peerings to the same node has been added, useful for nodes with multiple network interfaces
- The priority can be configured by specifying `?priority=X` in a `Peers` or `Listen` URI, or by specifying `Priority` within a `MulticastInterfaces` configuration entry
- Priorities are values between 0 and 254 (default is 0), lower numbers are prioritised and nodes will automatically negotiate the higher of the two values
### Changed
- On Linux, `SO_REUSEADDR` is now used on the multicast port instead of `SO_REUSEPORT`, which should allow processes running under different users to run simultaneously
### Fixed
- Adding peers using the `InterfacePeers` configuration option should now work correctly again
- Multiple connections from the same remote IP address will no longer be incorrectly dropped
- The admin socket will no longer incorrectly claim TCP connections as TLS
- A panic that could occur when calling `GetPeers` while a peering link is being set up has been fixed
## [0.4.5] - 2022-10-15
### Added
