+- perf: KcpServer/Client RawReceive now call socket.Poll to avoid non-blocking
+  socket's allocating a new SocketException in case they WouldBlock.

+V1.32 [2023-03-12]
+- fix: KcpPeer RawInput now doesn't disconnect in case of random internet noise
+
+V1.31 [2023-03-05]
+- KcpClient: Tick/Incoming/Outgoing can now be overwritten (virtual)
+- breaking: KcpClient now takes KcpConfig in constructor instead of in Connect.
+  cleaner, and prepares for KcpConfig.MTU setting.
+- KcpConfig now includes MTU; KcpPeer now works with KcpConfig's MTU, KcpServer/Client
+  buffers are now created with config's MTU.
+
+V1.30 [2023-02-20]
+- fix: set send/recv buffer sizes directly instead of iterating to find the limit.
+  fixes: https://github.com/MirrorNetworking/Mirror/issues/3390
+- fix: server & client sockets are now always non-blocking to ensure main thread never
+  blocks on socket.recv/send. Send() now also handles WouldBlock.
+- fix: socket.Receive/From directly with non-blocking sockets and handle WouldBlock,
+  instead of socket.Poll. faster, more obvious, and fixes Poll() looping forever while
+  socket is in error state. fixes: https://github.com/MirrorNetworking/Mirror/issues/2733

+  https://github.com/MirrorNetworking/Mirror/issues/3361
+
+V1.27 [2023-01-08]
+- KcpClient.Connect: invoke own events directly instead of going through peer,
+  which calls our own events anyway
+- fix: KcpPeer/Client/Server callbacks are readonly and assigned in constructor

+V1.26 [2022-12-22]
+- KcpPeer.RawInput: fix compile error in old Unity Mono versions
+- fix: KcpServer sets up a new connection's OnError immediately.
+  fixes KcpPeer throwing NullReferenceException when attempting to call OnError
+  after authentication errors.
+- improved log messages
+
+V1.25 [2022-12-14]
+- breaking: removed where-allocation. use IL2CPP on servers instead.
+- breaking: KcpConfig to simplify configuration
+- high level cleanups
+
+V1.24 [2022-12-14]
+- KcpClient: fixed NullReferenceException when connection without a server.

+
+V1.23 [2022-12-07]
+- KcpClient: rawReceiveBuffer exposed

+  - KcpPeer instead of KcpConnection, KcpClientConnection, KcpServerConnection
+  - RawSend/Receive can now easily be overwritten in KcpClient/Server.
+    for non-alloc, relays, etc.
+
+V1.20 [2022-11-22]
+- perf: KcpClient receive allocation was removed entirely.
+  reduces Mirror benchmark client sided allocations from 4.9 KB / 1.7 KB (non-alloc) to 0B.
+- fix: KcpConnection.Disconnect does not check socket.Connected anymore.
+  UDP sockets don't have a connection.
+  fixes Disconnects not being sent to clients in netcore.
+- KcpConnection.SendReliable: added OnError instead of logs
+
+V1.19 [2022-05-12]
+- feature: OnError ErrorCodes
+
+V1.18 [2022-05-08]
+- feature: OnError to allow higher level to show popups etc.
+- feature: KcpServer.GetClientAddress is now GetClientEndPoint in order to
+  expose more details
+- ResolveHostname: include exception in log for easier debugging
+- fix: KcpClientConnection.RawReceive now logs the SocketException even if
+  it was expected. makes debugging easier.
+- fix: KcpServer.TickIncoming now logs the SocketException even if it was
+  expected. makes debugging easier.
+- fix: KcpClientConnection.RawReceive now calls Disconnect() if the other end
+  has closed the connection. better than just remaining in a state with unusable
+  sockets.
+
+V1.17 [2022-01-09]
+- perf: server/client MaximizeSendReceiveBuffersToOSLimit option to set send/recv
+  buffer sizes to OS limit. avoids drops due to small buffers under heavy load.
+
+V1.16 [2022-01-06]
+- fix: SendUnreliable respects ArraySegment.Offset
+- fix: potential bug with negative length (see PR #2)
+- breaking: removed pause handling because it's not necessary for Mirror anymore
+
+V1.15 [2021-12-11]
+- feature: feature: MaxRetransmits aka dead_link now configurable
+- dead_link disconnect message improved to show exact retransmit count
+
+V1.14 [2021-11-30]
+- fix: Send() now throws an exception for messages which require > 255 fragments
+- fix: ReliableMaxMessageSize is now limited to messages which require <= 255 fragments
+
+V1.13 [2021-11-28]
+- fix: perf: uncork max message size from 144 KB to as much as we want based on
+  receive window size.
+    fixes https://github.com/vis2k/kcp2k/issues/22
+    fixes https://github.com/skywind3000/kcp/pull/291
+- feature: OnData now includes channel it was received on
+
+V1.12 [2021-07-16]
+- Tests: don't depend on Unity anymore
+- fix: #26 - Kcp now catches exception if host couldn't be resolved, and calls
+  OnDisconnected to let the user now.
+- fix: KcpServer.DualMode is now configurable in the constructor instead of
+  using #if UNITY_SWITCH. makes it run on all other non dual mode platforms too.
+- fix: where-allocation made optional via virtuals and inheriting
+  KcpServer/Client/Connection NonAlloc classes. fixes a bug where some platforms
+  might not support where-allocation.
+
+V1.11 rollback [2021-06-01]
+- perf: Segment MemoryStream initial capacity set to MTU to avoid early runtime
+  resizing/allocations
+
+V1.10 [2021-05-28]
+- feature: configurable Timeout
+- allocations explained with comments (C# ReceiveFrom / IPEndPoint.GetHashCode)
+- fix: #17 KcpConnection.ReceiveNextReliable now assigns message default so it
+  works in .net too
+- fix: Segment pool is not static anymore. Each kcp instance now has it's own
+  Pool<Segment>. fixes #18 concurrency issues
+
+V1.9 [2021-03-02]
+- Tick() split into TickIncoming()/TickOutgoing() to use in Mirror's new update
+  functions. allows to minimize latency.
+  => original Tick() is still supported for convenience. simply processes both!
+
+V1.8 [2021-02-14]
+- fix: Unity IPv6 errors on Nintendo Switch
+- fix: KcpConnection now disconnects if data message was received without content.
+  previously it would call OnData with an empty ArraySegment, causing all kinds of
+  weird behaviour in Mirror/DOTSNET. Added tests too.
+- fix: KcpConnection.SendData: don't allow sending empty messages anymore. disconnect
+  and log a warning to make it completely obvious.
+
+V1.7 [2021-01-13]
+- fix: unreliable messages reset timeout now too
+- perf: KcpConnection OnCheckEnabled callback changed to a simple 'paused' boolean.
+  This is faster than invoking a Func<bool> every time and allows us to fix #8 more
+  easily later by calling .Pause/.Unpause from OnEnable/OnDisable in MirrorTransport.
+- fix #8: Unpause now resets timeout to fix a bug where Mirror would pause kcp,
+  change the scene which took >10s, then unpause and kcp would detect the lack of
+  any messages for >10s as timeout. Added test to make sure it never happens again.
+- MirrorTransport: statistics logging for headless servers
+- Mirror Transport: Send/Receive window size increased once more from 2048 to 4096.
+
+V1.6 [2021-01-10]
+- Unreliable channel added!
+- perf: KcpHeader byte added to every kcp message to indicate
+  Handshake/Data/Ping/Disconnect instead of scanning each message for Hello/Byte/Ping
+  content via SegmentEquals. It's a lot cleaner, should be faster and should avoid
+  edge cases where a message content would equal Hello/Ping/Bye sequence accidentally.
+- Kcp.Input: offset moved to parameters for cases where it's needed
+- Kcp.SetMtu from original Kcp.c
+
+V1.5 [2021-01-07]
+- KcpConnection.MaxSend/ReceiveRate calculation based on the article
+- MirrorTransport: large send/recv window size defaults to avoid high latencies caused
+  by packets not being processed fast enough
+- MirrorTransport: show MaxSend/ReceiveRate in debug gui
+- MirrorTransport: don't Log.Info to console in headless mode if debug log is disabled
+
+V1.4 [2020-11-27]
+- fix: OnCheckEnabled added. KcpConnection message processing while loop can now
+  be interrupted immediately. fixes Mirror Transport scene changes which need to stop
+  processing any messages immediately after a scene message)
+- perf: Mirror KcpTransport: FastResend enabled by default. turbo mode according to:
+  https://github.com/skywind3000/kcp/blob/master/README.en.md#protocol-configuration
+- perf: Mirror KcpTransport: CongestionControl disabled by default (turbo mode)
+
+V1.3 [2020-11-17]
+- Log.Info/Warning/Error so logging doesn't depend on UnityEngine anymore
+- fix: Server.Tick catches SocketException which happens if Android client is killed
+- MirrorTransport: debugLog option added that can be checked in Unity Inspector
+- Utils.Clamp so Kcp.cs doesn't depend on UnityEngine
+- Utils.SegmentsEqual: use Linq SequenceEqual so it doesn't depend on UnityEngine
+=> kcp2k can now be used in any C# project even without Unity
+
+V1.2 [2020-11-10]
+- more tests added
+- fix: raw receive buffers are now all of MTU size
+- fix: raw receive detects error where buffer was too small for msgLength and
+  result in excess data being dropped silently
+- KcpConnection.MaxMessageSize added for use in high level
+- KcpConnection.MaxMessageSize increased from 1200 bytes to to maximum allowed
+  message size of 145KB for kcp (based on mtu, overhead, wnd_rcv)
+
+V1.1 [2020-10-30]
+- high level cleanup, fixes, improvements
+
+V1.0 [2020-10-22]
+- Kcp.cs now mirrors original Kcp.c behaviour
+  (this fixes dozens of bugs)
+
+V0.1
+- initial kcp-csharp based version
