- fix: KcpClients now need to validate with a secure cookie in order to protect against
UDP spoofing. fixes:
https://github.com/MirrorNetworking/Mirror/issues/3286
[disclosed by IncludeSec]
- KcpClient/Server: change callbacks to protected so inheriting classes can use them too
- KcpClient/Server: change config visibility to protected
V1.34 [2023-03-15]
