✨ Features

  • It is now possible to obtain `RelayAllocationId`, `RelayConnectionData`, and `RelayHMACKey` structures from byte arrays using their static `FromByteArray` method.
  • A new constructor for `RelayServerData` is now provided with argument types that better match those available in the models returned by the Relay SDK. The "RelayPing" sample has been updated to use this constructor.
  • New constructors for `RelayServerData` are now provided with argument types that better match those available in the models returned by the Relay SDK. The "RelayPing" sample has been updated to use them constructor.
  • `NetworkSettings` now has a `IsCreated` property which can be used to check if it's been disposed of or not.

🔄 Changes

  • Reverted the fix for the `SimulatorPipelineStage` always using the same random seed, reverting its behavior to always be deterministic. If non-determinism is desired, use a dynamic random seed (e.g. `Stopwatch.GetTimestamp`).
  • The default network interface (`UDPNetworkInterface`) does not enable address reuse anymore. This means `NetworkDriver.Bind` will now always fail if something else is listening on the same port, even if that something else is bound to a wildcard address and we are trying to bind to a specific one.
  • Added: `NetworkDriverIdentifierParameter` struct and `NetworkSettings.WithDriverIdentifierParameters()` method that can be use to identify the NetworkDriver instances with a custom label. Currently this method serves no purpose, but might be used in future releases to make debugging easier.
  • The `InitialEventQueueSize`, `InvalidConnectionId`, and `DriverDataStreamSize` fields were removed from `NetworkParameterConstants`. They all served no purpose anymore.
  • If using Relay, it is now possible to call `Connect` without an endpoint (the endpoint would be ignored anyway). This extension to `NetworkDriver` is provided in the `Unity.Networking.Transport.Relay` namespace.
  • The `RelayServerData.HMAC` field is now internal. There was no use to this being available publicly.
  • The deprecated constructor for `RelayServerData` that was taking strings for the allocation ID, connection data, and key has been completely removed.
  • The deprecated `RelayServerData.ComputeNewNonce` method has also been removed. One can provide a custom nonce using the "low level" constructor of `RelayServerData`. Other constructors will select a new one automatically.

🔧 Bug Fixes

  • Fixed an issue where a duplicated reliable packet wouldn't be processed correctly, which could possibly lead to the entire reliable pipeline stage stalling (not being able to send new packets).
  • Fixed an issue where a warning about having too many pipeline updates would be spammed after a connection was closed.
  • Fixed an issue where pipeline updates would be run too many times, which would waste CPU and could lead to the warning about having too many pipeline updates being erroneously logged.
  • Fixed issues with `ReliableSequencePipelineStage` that would, in rare circumstances, lead to failure to deliver a reliable packet.
  • Fixed an issue where sending maximally-sized packets to the Relay when using DTLS would fail with an error about failing to encrypt the packet.
  • Fixed an issue when using secure WebSockets where the stream would become corrupted, resulting in failure to decrypt packets (and eventually potentially a crash of the server).
