    * SteamGameServerUtils.GetEnteredGamepadTextInput()
    * SteamGameServerNetworking.SendP2PPacket()
    * SteamGameServerNetworking.IsP2PPacketAvailable()
    * SteamGameServerNetworking.ReadP2PPacket()

The Standalone package is for non-Unity .NET applications. Prefer the .unitypackage if you are using Unity.

Release 3.0.0

Feature: Updated to Steamworks SDK 1.29a.
Feature: Steamworks.NET now throws an exception if Steamworks is not Initialized when calling interface functions.
Feature: We now throw an exception when interface functions are called on non-supported platforms. (Like Mobile)
Feature: 64Bit OSX (Universal) is now supported!
Feature: Included all of the Steamworks global functions in NativeMethods.
Feature: Callbacks and CallResults can now be dispatched to multiple functions.

Changed: Completely reworked the Callback/CallResult backends.*
Changed: CallResult::Set() can now take a delegate function. You are no longer required to set one when you create the CallResult. (Like the C++ API)
Changed: Removed the Linux Launch Scripts as they are no longer needed!
Changed: Statically linked to the Visual Studio runtime so the VS2010 redistributable is no longer required!

Fixed: The second last argument in SteamUserStats.GetDownloadedLeaderboardEntry changed from out int to int[].
Fixed: Resolved a memory corruption issue with UGC tags.
Fixed: Some lesser used Callback structs were the wrong size on some platforms resulting in corrupted results.

• *** This required an API Change.**

• Upgrade Instructions:

  • Find all usages of "new Callback<>();" in your code.
  • Replace each use with "Callback<>.Create()".
  • Additionally you must now store the Callback<> returned by Create() so that it does not get Garbage-Collected.
  • This results in the following:

  class YourClass : MonoBehavior {
      protected Callback<UserStatsReceived_t> m_UserStatsReceived;
      void OnEnable() {
          m_UserStatsReceived = Callback<UserStatsReceived_t>.Create(OnUserStatsReceived);
      }
      private void OnUserStatsReceived(UserStatsReceived_t pCallback) {
      }
  }
  

The Standalone build is for Non-Unity projects, 'Source Code' is for Unity based projects.

2.1.0

• Improved the Steam types so that they are all Comparable and Castable
• Made SetWarningMessageHook easier to use
• Fixed Regression caused by marshalling structs as return values on Unity's Linux Mono
• 64 Bit support on both Linux and Windows (Steam does not provide a 64bit OSX dylib!)

2.0.0

Steamworks.NET 2.0.0 provides some rather large changes most notable being:

• Reorganized folder structure (If you were using gitmodules to pull Steamworks.NET into your Plugins/ folder then that will no longer work.) (This is due to the Editor scripts and Standalone project being included)
• All comments/documentation from the C++ headers are now replicated in C#.
• Included 3 Editor scripts that improve the ease of installation and ease of building.
• Created a standalone project for non-Unity based games.
• Many Improvements to the automatically generated wrapper.
• Included SteamGameServer_* free functions
• Updated Steamworks to 1.28
• Redesigned the CallResult API to end up even closer to the C++ API
