What's New in Dalamud v9

Dalamud v9 is the next major version of Dalamud, to be released together with Patch 6.5. This is a high-level overview of changes. You can see a code diff of all of these changes here.

Key Information

  • Branch: v9 (view on GitHub)
  • Release Date: Targeted to release alongside Patch 6.5 (estimated September/October 2023).
  • API Level: 9
  • .NET Version: .NET 7.0
    • .NET 8 is due for official release in November 2023. Due to release timing, we will be targeting .NET 7.0 for v9, and will upgrade to .NET 8 in a future release, when we can confirm that it is stable on all platforms (Windows, Wine, OS X).

New Features

  • The console (/xllog) has been redone, and now lets you create filters that can filter to specific plugins.
  • Added a new plugin-specific logging class that you can receive as a service instance via the IPluginLog type.
    • Static functions in PluginLog have been deprecated, and we recommend that you move to the new service. They were slow and unreliable, due to having to look up the calling plugin via reflection, and won’t support new filtering features in the improved console.
    • We are planning to remove the static functions in a future API cycle.
  • Extended DtrBarEntry to now allow for a tooltip, and an OnClick event, to add even more functionality to your DTR bar entries.
  • Added IAddonLifecycle and IAddonEventManager services which simplify access to addons greatly.
  • Added comprehensive new service to acquire ImGui textures from game icons/textures via ITextureProvider, detailed below.
  • Added various new functions to manipulate colors for UI work in Dalamud.Interface.ColorHelpers.

Major Changes


  • All services must be used via interfaces, their implementations are now private.
    • This allows us to create per-plugin implementations of services, which will be able to safely dispose of plugin-specific resources - something we have never been able to do before reliably - and opens up the possibility of creating mocks that allow for testing outside of the game.
    • We can also now build features that rely on detecting what plugin is using a service, like plugin-scoped logs and reliable command lists.
    • To migrate, you only have to change the type used to the interface equivalent in the Dalamud.Plugin.Services namespace (e.g. DataManager => IDataManager)
  • IDataManager.ClientOpcodes and IDataManager.ServerOpcodes have been removed. Dalamud systems that use opcodes directly will now use hooks instead. We recommend any plugin that has been using these opcodes to switch to hooks.

UI and ImGui

  • The UiBuilder.OpenMainUi event has been added, which you should subscribe to to open your plugin's "main interface", if applicable
    • This is shown as a separate, highlighted button in the plugin installer, in addition to the already existing OpenConfigUi button
  • Texture- and Icon-related functions on DataManager have been removed and are now available in a new service, ITextureProvider.
    • API has been simplified in a major way and now properly supports high-resolution textures
    • Icons and textures are now only loaded once globally when requesting them using this service, reducing memory usage
    • Icons and textures are now automatically unloaded if not drawn for more than 2 seconds, and will be reloaded transparently if they are accessed again by your plugin
    • An API that allows plugins to replace paths to tex files has been added. This means that you no longer manually have to implement this functionality to make your plugin compatible with e.g. UI mods.
    • ITextureProvider is designed for ImGui specific use cases. Plugins that need to work with raw tex files should implement their own logic.
  • All Dalamud APIs that interact with textures now return IDalamudTextureWrap, and IDalamudTextureWrap no longer inherits from the TextureWrap type in ImGuiScene. This has been done to decouple the public API from ImGuiScene, and to remove the need for plugins to reference it.
    • To migrate, you merely need to switch the types used. The exposed API is exactly the same.
    • IDalamudTextureWrap.Size (Vector2) has been added, finally.
  • IDisposable ImGui-helpers have been moved to the main Dalamud assembly and are now accessible via the Dalamud.Interface.Utility namespace
    • We recommend using these for any new UI, as they are much safer and reduce the chance of crashes caused by misbehaving UI code


  • Obsolete constructors for Hook<T> and the static Hook<T>.FromX() functions have been removed.
    • Please use the equivalent functions in the IGameInteropProvider service
    • IGameInteropProvider.HookFromSignature() has been added
  • SignatureHelper.Initialize() has been removed. Please use IGameInteropProvider.InitializeFromAttributes().

Minor Changes

  • Util.HttpClient has been removed in favor of allowing plugins to manage their own HTTP lifecycles.
    • You can use Dalamud.Networking.Http.HappyEyeballsCallback as your SocketsHttpHandler.ConnectCallback to enable improved IPv6 connection handling to dual-stack servers.
  • SeStringManager has been removed. Please use SeStringBuilder instead.
  • ChatHandlers has been removed.
    • ChatHandlers.IsAutoUpdateComplete is now available as DalamudPluginInterface.IsAutoUpdateComplete
    • ChatHandlers.MakeItalics() can be accessed via SeStringBuilder
  • Util.CopyTo() has been removed, as it has been added to the standard library as Stream.CopyTo().
  • DalamudPluginInterface.PluginNames and PluginInternalNames have been replaced in favor of InstalledPlugins, which provides more context.
  • Obsolete/non-functional icons in FontAwesomeIcon have been removed.
  • DataManager.IsDataReady has been removed, as it is always true when plugins are loaded.
  • SeStringBuilder.AddItemLink() now correctly adds a full item link, instead of only adding an ItemPayload.
  • Util.IsLinux() has been changed to Util.IsWine(). Util.GetHostPlatform() has been added to get the actual platform the game is running on - this relies on a special env var that may not be present on all environments Dalamud can run under yet.
  • The Serilog property SourceContext is no longer used for Dalamud systems. Plugins implementing their own logging systems should write their plugin internal name to the Dalamud.PluginName property instead, otherwise, filtering in the new console will not work.
  • UIBuilder.GposeActive has been moved to IClientState.IsGPosing, and is now more reliable/will only be true if the user is actually in GPose.
  • IDalamudPlugin.Name has been removed. This has not been shown anywhere in more than 2 years.
  • Dev-Plugins without a manifest are no longer supported. Please have a manifest or use DalamudPackager!
  • Most FlyTextKind enum members have been renamed, see commit here.


These changes have been made after the official stabilization.

  • SigScanner was mistakenly made internal, making it impossible for plugins to create their own scanners
    • SigScanner was made public with the same API, and the internal service implementation was decoupled
