LiteNetLib 2.0

What's Changed

• Set C# language version to 8 and minimal .net version to netstandard2.1

• Add simplified and faster LiteNetManager with LiteNetPeer which has 1 reliable-ordered channel, 1 reliable-unordered, 1 sequenced channel (and unreliable channel) which is enough for many cases. ReliableSequenced channel is same as reliable-ordered in LiteNetPeer (where old NetManager can have more than 1 channel per DeliveryMethod as before and fully support ReliableSequenced channels for very specific use-cases)

• Ntp requests now only supported in full NetManager

• Merge additional listener interfaces into INetEventListener with default empty implementation. Merged methods:

  • OnMessageDelivered
  • OnNtpResponse
  • OnPeerAddressChanged

• Add reliable packet merging which drastically increase speed of ReliableOrdered and ReliableUnordered channels when sending many small packets

• Fix .net8 receive bug #552

• Add Configurable Resend packet delay for reliable packets (#567)

• Remove not threadsafe ConnectedPeerList. Add GetConnectedPeers instead. Fix #584

• Increment packet loss in reliable channel only when there is pending packets. Fix #564

• Optimizations and some additional protections

• Simplify code using Spans and remove old #ifdefs for older .net versions

Full Changelog: 1.3.1...1.3.5

LiteNetLib 1.3.1

Changes in 1.3.1

• Fix crash when sending Merged byte without data
• Add .net8 and .net7 targets (and nuget variants) to support specific features
• Remove .net5 target because EOL. You can use .NET Standard for .net5.

Changes in 1.3.0

• Stop running NetManagers in Unity in OnApplicationQuit (when using library source code)
• Disable MTU discovery by default because some routers can break detection and connection in result. Remove UseSafeMtu (for this just use MtuOverride). To enable MTU discovery set NetManager.MtuDiscovery to true
• Add optional argument max processed events into PollEvents and ManualReceive (fix #528)
• Add methods to serialize and deserialize array of nested INetSerializable into NetDataReader/Writer
• Add GUID serialization to NetDataWriter/Reader and NetSerializer/NetPacketProcessor
• Add SendUnconnectedMessage with ReadOnlySpan argument
• Add NetDataWriter.AsReadOnlySpan()
• Add GetRemainingBytesMemory method to NetDataReader. (fix #560)
• Make PeerTimers and ElapsedMilliseconds as float (fix #521)
• Improve NetDataWriter/Reader strings.
• Add PutLargeString (with int size) and GetLargeString into NetDataWriter/Reader
• Fix ObjectDisposedException with Native Sockets (fix #542)
• Lock unreliable channel only if there is pending packets
• Unreliable packets optimization

For installation in typical .NET project use nuget package
For Unity use sources zip and copy directory LiteNetLib to your project

LiteNetLib 1.2.0

• Derive NetPeer from IPEndPoint (so to get EndPoint of peer you just use peer instead of peer.RemoteEndPoint)
• Add .NET8+ garbage less Socket.Send/Socket.Receive
• Add .NET5+ Member Trimming Annotations
• Add NetDataReader.Get(out ...) methods
• Add NetManager.SendToAll with ReadOnlySpan
• Add NetDataReader.GetRemainingBytesSpan()
• Add optional NetManager.DontRoute option for sockets (for specific cases)
• Sort Network Interfaces to prefer Wifi over Cellular (local ip)
• Process shutdown error (for specific cases)
• Fix AllowPeerAddressChange works only if you implement IPeerAddressChangedListener (now it works without implementing)
• Better protections for broken data (fixes some critical cases that can "crash" server)
• Overall optimizations

LiteNetLib 1.1.0

• Use old behaviour of reading empty strings from NetDataReader (string.Empty instead null as in 0.9.5.2)
• Reverted channels code to 0.9.5.2 (change ConcurrentQueue that spawns garbage back to Queue)
• Don't get from pool packets bigger than MaxSinglePacketSize (0.9.5.2 behaviour)
• Remove dual mode support (because it slower than separate sockets, also doesn't work on some platforms including OSX).
• Use one thread for both sockets IPv4 and IPv6.
• Replace event queue by linked list type of queue. Fixes possible multithreaded bugs
• Update documents to netstandard2.1
• PausedSocketFix (iOS unity) improved

LiteNetLib 1.0.1.1

• Experimental NetManager.UseNativeSockets mode that reduces GC of .NET sockets and improves performance especially for "server" usage.
• Add PooledPackets for faster Send calls without copy CreatePacketFromPool(DeliveryMethod deliveryMethod, byte channelNumber) SendPooledPacket(PooledPacket packet, int userDataSize)
• Add channel to the OnNetworkReceive event
• Add NetPeer.RemoteId that represents peer id assigned on remote side (typically server) that can be used as Server Peer Id.
• Add .asmdef for Unity
• Add ReadOnlySpan<byte> send
• Add AllowPeerAddressChange option (false by default) that allows clients to change Endpoint when switching from 4G to Wifi or something similar
• Add TryGetPeerById helper method
• Add NetDataWriter.EnsureFit method to resize internal array if data not fits
• Add RoundTripTime to peer (ping is RTT/2 leaved for compatibility with old code)
• Add NetworkReset (WSAENETRESET - 10052) to ignored errors which fixes some disconnection cases
• Remove NetDataWriter from NetPacketProcessor to avoid multithreading "issues". Add Get<T> to NetDataReader for structs and separate method for classes with constructor argument to avoid Activator.CreateInstance slow call
• Correctly check new MTU when using extra package layer
• Update minimal .net version to 4.6 (C# 7.3). Minimal supported Unity version now is 2018.3
• Increased overall performance. Less copies, less "virtual" calls, other things

LiteNetLib 0.9.5.2

• Fix offset in SendInternal for fragmented packets
• Optimize resolve address
• Optimize NetPacketProcessor hashing
