+This is a Windows x64 build of ENet-CSharp.
+
+If you require a version of ENet for 32 Bit computer systems (ie. Windows 7/8/10 32Bit) then please get in touch, or you can install the requirements yourself and compile it using ENet-CSharp's MSBuild-based build system. Get in touch if you want me to compile them for you, but keep in mind that I do not support them when reporting bugs.

+ENET Pre-compiled Binary Library Blobs
+==========================
+This folder contains pre-compiled binaries for a variety of different platforms.
+
+A brief summary of these folders are as follows:
+
+- Windows, Mac, Linux
+-- 64bit (x64)
+
+- Android (Kitkat 4.4 minimum target OS)
+-- ARMv7 (armeabi-v7a), ARMv8/AArch64 (arm64-v8a)
+
+- iOS
+-- FAT Library (armv7 + arm64). Targeted for iOS 8 minimum. Unsigned library.
+
+DEBUG VERSIONS
+===============
+Debug versions of the libraries can be obtained at https://github.com/SoftwareGuy/ENet-CSharp/releases.
+Otherwise you can also compile the library yourself with Debug enabled.
+
+DOT POINTS
+===========
+1. 32bit Support for Ignorance has been removed. Originally, I did not want to support 32bit operating systems,
+however due to some countries in the world still stuck in the 32bit era (Brasil, some Russian areas, etc) I added them as a
+goodwill gesture. However, since those who needed the libraries have now vanished, I have stopped building 32bit versions of ENet.
+
+COMPILE THE CODE YOURSELF
+=========================
+If you don't trust the above binaries then git clone the ENET-CSharp repository (http://github.com/SoftwareGuy/ENet-CSharp) and read the readme.
+
+EXCLUSION INSTRUCTIONS
+======================
+No need, the meta data will cover that for you.
+
+Still don't know what to do with these? Drop by the Mirror discord and post in the Ignorance channel.

+V1.12 [2021-07-16]
+- where-allocation removed. will be optional in the future.
+- 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.
+
+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. 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 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

+encryption with websocket secure.
+
+How to use:
+ Replace your existing Transport with SimpleWebTransport on your NetworkManager
+
+Requirements:
+ Unity 2018.4 LTS
+ Mirror v18.0.0
+
+Documentation:
+ https://mirror-networking.gitbook.io/docs/
+ https://github.com/MirrorNetworking/SimpleWebTransport/blob/master/README.md
