  • "Packed Mode" (play mode) has been renamed "Use Existing Build (requires built groups)"
  • There is no longer a current "Build Script" (Build Script menu in Addressables window). Instead the script is selected when triggering the build.
  • Schemas have been given display names to be more clear of their intent BundledAssetGroupSchema.
    • BundledAssetGroupSchema displays as "Content Packing & Loading"
      • ContentUpdateGroupSchema displays as "Content Update Restriction"
    • Bundle and Asset providers within schema settings are named more descriptively
  • Profile management is in its own window ("Profiles")
  • Label management is in its own window
  • "Prepare for Content Update" is now under the "Tools" menu (in Addressables window), and is called "Check for Content Update Restriction"
  • "Build for Content Update" is "Update a Previous Build" (still in "Build" menu of Addressables window).
  • "Profiler" window has been renamed "Event Viewer". It's more accurate, and avoids confusion with "Profilers" window.
• Added additional parameter to AssetReference.LoadSceneAsync method to match Addressables.LoadSceneAsync API
• Added AssetReference.UnloadScene API
• Fixed issue with WebGL builds where re-loading the page was causing an exception to get thrown.
• Fixed Analyze bug where bundle referenced multiple times was flagged as duplicate.
• Fixed issue with hashing dependencies that led to frequent "INCORRECT HASH: the same hash (hashCode) for different dependency lists:" errors.
• Update AddressableAssetEntry cached path to new modified asset entry paths.
• Storing the KeyData string from ContentCatalogData on disk instead of keeping it in memory as it can get quite large.
• Fixed Custom Hosting Service window so it won't close when focus is lost.
• Fixed issue with AudioMixerGroups not getting the proper runtime type conversion for the build.
• Fixed invalid location load path when using "only hash" bundle naming option in 'content packing and loading' schema.
• Removed content update hash from final AssetBundle filename.
• Removed exception in Analyze that was triggering when "Fix Selected Rules" was bundling in Un-fixable rules.
• (SBP) Fixed an edge case where Optimize Mesh would not apply to all meshes in the build.
• (SBP) Fixed an edge case where Global Usage was not being updated with latest values from Graphics Settings.
• (SBP) Fixed Scene Bundles not rebuilding when included prefab changes.
• Added APIs to update content catalog at runtime: CheckForCatalogUpdates() and UpdateCatalogs().

[1.2.4] - 2019-09-13

• Further improvement to the % complete calculations.
  • Note that this is an average of dependency operations. Meaning a LoadAssetsAsync call will average the download, and the loading progress. DownloadDependenciesAsync currently has one extra op, so the download will crawl to 50%, then jump to done (we will look into removing that). Similarly any op that is called before Addressables init's will jump to 50% once init is done.

[1.2.3] - 2019-09-10

• Actually "Made ContentUpdateScript.GatherModifiedEntries public."

[1.2.2] - 2019-09-09

• Made ContentUpdateScript.GatherModifiedEntries public.
• Added sub-object support to AssetReference. For example, you can now have an AssetReference to a specific sprite within a sprite atlas.
• Added sub-object support to addresses via [] notation. For example, sprite atlas "myAtlas", would support loading that atlas via that address, or a sprite via "myAtlas[mySprite]"
• Fixed issue with Content Update workflow. Assets that don't change groups during Content Update now remain in the same bundle.
• Added funtionality to allow multiple diagnostic callbacks to the ResourceManager.
  • Added error and IResourceLocation to the callback.
• Added default parameter to DownloadDependenciesAsync to allow auto releasing of the the operation handle on completion.
• Added memory management documentation.
• Changed OnlyHash naming option to remove folder structure. This is a workaround to Windows long-file-path issues.
• Made AssetReference interfaces virtual
• Fixed hash calculations to avoid collisions
• Added overload for GetDownloadSizeAsync. The overload accepts a list of keys and calculates their total download size.
• Improved percent complete calculations for async opertions.

[1.1.10] - 2019-08-28

• Fix for all files showing "Missing File" in the addressables window.
• Fix for waiting on a successfully done Task

[1.1.9] - 2019-08-22

• Fixed drag and drop NullRef in main addressables window.
• Fixed AudioMixer type assets getting stripped from bundles.
• Fixed issue where failed async operations weren't getting released from the async operation cache.
• Fix unloading of scenes so that the dependencies will wait for the unload operation to complete before unloading. This was causing an occasional 1-frame visual glitch during unload.
• Fixed scenario where AsyncOperation Task fails to complete when AsyncOperation has already completed.
• Fixed a missed init-log that was stuck always-logging.
• Fixed issue around assets losing dependencies when unloaded then reloaded. This would manifest most often as sprites losing their texture or prefabs losing their shader/material/texture.
• Changed checks for determining if a path is remote or not from looking for "://" to looking for starting with "http". "://" is still used to determine if the asset should be loaded via UnityWebRequest or not.
• Added Analyze Rule to show entire Asset Bundle layout
• Added progress bars and some optimizations for calculating analyze rules

[1.1.7] - 2019-07-30

• Fixed chain operation percent complete calculation.
• Fixed scenario where deleting assets would also delete groups that have similar names.
• Fix in bundle caching bug surrounding bundles with '.' in their name
• Significant improvements to the manual pages
• Made the many init-logs not log unless ADDRESSABLES_LOG_ALL is defined in player settings (other logs always worked this way, init didn't).
• Prevented NullReferenceException when attempting to delete entries in the Addressables window.
• Fix for building by label (Bundle Mode = Pack Together By Label)
• Removed ability to mark editor-only assets as addressable in GUI
• Better fix to Editor types being added to the build
• Made BuiltIn Data group read-only by default.
• Fixed NullRef caused by an invalid (BuildIn Data) group being default during a build.
• Fixed path where LoadResourceLocationsAsync could still throw an exception with unknown key. Now it should not, and is a safe way to check for valid keys.
  • If Key does not exist but nothing else goes wrong, it will return an empty list and Success state.
• Fixed NullRef caused when there was a deleted scene in the scenes list.
• BuildCompression for Addressables can now be driven from the default group. If necessary WebGL builds will fallback to LZ4Runtime and all other build targets will fallback to LZMA.
• Added options for bundle naming: AppendHash, NoHash, OnlyHash.
  • As a temporary workaround for updating issues, we recommend setting all groups with StaticContent=true to be NoHash. This will make sure the updated catalog still refers to the correct unchanged bundle. An actual fix will be out in a few releases.

[1.1.5] - 2019-07-15

• Fixed scenario where scene unload simultaneously destroys objects being instantiated in different scenes.
• Cleaned up SetDirty logic to remove excessive dirtying of assets.

[1.1.4-preview] - 2019-06-19

• Fixed an issue where Editor only types were being added to the build.

[1.1.3-preview] - 2019-06-17

• BREAKING CODE CHANGES
  • ReleaseInstance will now return a bool saying if it successfully destroyed the instance. If an instance is passed in that Addressables is unaware of, this will return false (as of 0.8 and earlier, it would print a log, and still destroy the instance). It will no longer destroy unknown instances.
• Added PrimaryKey to the IResourceLocation. By default, the PrimaryKey will be the address. This allows you to use LoadResourceLocationsAsync and then map the results back to an address.
• Added ResourceType to IResourceLocation.
  • This allows you to know the type of a location before loading it.
  • Fixes a problem where calling Load*(key) would load all items that matched the key, then filter based on type. Now it will do the filter before loading (after looking up location matches)
  • This also adds a Type input to LoadResourceLocationsAsync. null input will match all types.
• Safety check AssetReference.Asset to return null if nothing loaded.
• New rule added to Analyze window - CheckResourcesDupeDependencies - to check for dependencies between addressables and items in Resources
• Added group rearranging support to the Addressables window.
• Improved logging when doing a Prepare for Content Update.
• Added versions of DownloadDependencies to take a list of IResourceLocations or a list of keys with a MergeMode.
• Fixed scenario where Task completion wouldn't happen if operation was already in a certain state
• Made LoadResourceLocations no longer throw an exception if given unknown keys. This method is the best way to check if an address exists.
• Exposed AnalyzeRule class to support creating custom rules for Addressables analysis.
• Fixed some issues surrounding loading scenes in build scenes list via Addressables
• Removed using alias directives defined in global space.
• Proper disposal of DiagnosticEventCollector and DelayedActionManager when application closes.
• Added support for loading named sub-objects via an "address.name" pattern. So a sprite named "trees" with sub-sprites, could be loaded via LoadAssetAsync("trees.trees_0").
• Known issue: loading IList from a Texture2D or IList from an fbx will crash the player. The workaround for now is to load items by name as mentioned just above. Engine fix for this is on its way in.

[0.8.6-preview] - 2019-05-14

• Fix to make UnloadSceneAsync(SceneInstance) actually unload the scene.

[0.8.3-preview] - 2019-05-08

• BREAKING CODE CHANGES
  • Chagned all asynchronous methods to include the word Async in method name. This fits better with Unity's history and convention. They should auto upgrade without actually breaking your game.
  • Moved AsyncOperationHandle inside namespace UnityEngine.ResourceManagement
• Addressable Analyze changes:
  • Analyze has been moved into it's own window.
  • CheckSceneDupeDependencies Analyze rule has been added.
  • CheckDupeDependencies has been renamed into CheckBundleDupeDependencies.
  • Analyze Rule operations for individuals or specific sets of Analyze Rules has been added via AnalyzeRule selections.

[0.7.4-preview] - 2019-04-19

• Removed support for .NET 3.x as it is deprecated for Unity in general.
• Replaced IAsyncOperation with AsyncOperationHandle.
  • Once the asset is no longer needed, the user can call Addressables.Release, passing in either the handle, or the result the handle provided.
• Exposed AsyncOperationBase for creating custom operations
  • These operations must be started by ResourceManager.StartOperation
• Replaced IDataBuilderContext and it's inherited classes with simpler AddressablesDataBuilderInput. This class is fed into all IDataBuilder.BuildData calls.
• Fixed Nintendo Switch and PlayStation4 support.
• Simplified the IResourceProvider interface.
• Refactored build script interface. Made BuildScriptBase and the provided concrete versions easier to inherit from.
• Removed DelayedActionManager.
• Removed ISceneProvider. Users can implement custom scene loading using a custom AsyncOperationBase.
• Removed optional LRU caching of Assets and Bundles.
• Addressables Profiler now tracks all active async operations
• AssetBundles targetting StreamingAssets (by using the profile variable [UnityEngine.AddressableAssets.Addressables.BuildPath] now build to the Library instead of StreamingAssets. During the player build, these files are copied into StreamingAssets, then after the build, the copies are deleted. They are also built into platform specific folders (so building for a second platform will not overwrite data from a first build). We recommend deleting anything in Assets/StreamingAssets/aa.
• The addressables_content_state.bin is built into a platform specific folder within Assets/AddressableAssetsData/. We recommend deleting the addressables_content_state.bin in Assets/AddressableAssetsData to avoid future confusion.
• ScriptableBuildPipeline now purges stale data from its cache in the background after each build.
• Disabled Addressables automatic initialization. It will now initialize itself upon the first call into it (such as Load or Instantiate). To Initialize on startup instead of first use, call Addressables.Initialize().
• Optimized performance around instantiation and general garbage generation.
• Added per-group bundle compression settings.
• Fixes to AssetReference drawers.
• Improved the group template system for creating better defined asset groups.
• Fixed bug in bundle caching that caused GetDownloadSize to report incorrectly
• Cleaned up Load/Release calls to make sure all releases could take either the handle returned by Load, or the handle.Result.
• Added editor-only analytics (nothing added in runtime). If you have Analytics disabled in your project nothing will be reported. Currently only run when you build addressables, it includes data such as Addressables version and Build Script name.
• Fixed null ref issue when cleaning all the data builders
• KNOWN ISSUE: there is still an occasional issue with code stripping on iOS. If you run into iOS issues, try turning stripping off for now.

[0.6.8-preview] - 2019-03-25

• fixed Build For Content Update to no longer delete everything it built.

[0.6.7-preview] - 2019-03-07

• Fix for iOS and Android. Symptom was NullReferenceException dring startup resulting in nothing working. Fix requires re-running Build Player Content

[0.6.6-preview] - 2019-03-05

• BREAKING CODE CHANGES
  • to ease code navigation, we have added several layers of namespace to the code.
  • All Instantiate API calls (Addressables and AssetReference) have been changed to only work with GameObjects.
  • any hardcoded profile path to com.unity.addressables (specifically LocalLoadPath, RemoteLoadPath, etc) should use UnityEngine.AddressableAssets.Addressables.RuntimePath instead. For build paths, replace Assets/StreamingAssets/com.unity.addressables/[BuildTarget] with [UnityEngine.AddressableAssets.Addressables.BuildPath]/[BuildTarget] For load paths, replace Assets/StreamingAssets/com.unity.addressables/[BuildTarget] with {UnityEngine.AddressableAssets.Addressables.RuntimePath}/[BuildTarget]
  • We have removed attribute AssetReferenceTypeRestriction as it is cleaner to enforce type via generics
  • Attribute AssetReferenceLabelRestriction is renamed to AssetReferenceUILabelRestriction and must be surrounded by #if UNITY_EDITOR in your game code, to enforce it's editor-only capability
  • Modifications to IResourceProvider API.
  • Removed PreloadDependencies API. Instead use DownloadDependencies
• Content Update calculation has changed, this will invalide previously generated addressables_content_state.bin files.
  • Some types for content update were made private as a result of the above change.
• Minimum Unity version is now 2018.3 to address a build-time bug with progressive lightmapper.
• Moved all of the Resource Manager package to be contained within Addressables (no longer a stand alone package). No code change implications.
• Change to content catalog building:
  • Previous model built one catalog per group, wherever that group built it's data.
  • New model builds one catalog locally, and optionally one "remote". Remote location is set on the top level AddressableAssetSettings object.
  • Loading will now always check if remote has changes (if remote exists), and use local otherwise (or cached version of remote).
• LoadScene API now takes the LoadSceneParameters that were added to the engine in 2018.2
• Exposed AddressablesBuildDataBuilderContext.BuildScriptContextConstants for use in build scripts.
• Refactored AddressablesBuildDataBuilderContext.GetValue to take default parameter.
• Fixed Scene asset path to be consistent between different play modes in the catalog data.
• Exposed the various IDataBuilder implementations as public classes.
• Exposed asset and bundle provider types for BundledAssetGroupSchema.
• Fixed several bugs when loading catalogs from other projects.
• Added provider suffix to Initialization operation and Addressables.LoadCatalogsFromRuntimeData API to better support overriding providers.
• Exposed CachedProvider options in BundledAssetGroupSchema. Each unique set of parameters will generate a separate provider. There is also an option to force a group to have its own providers.
• Added IEnumerable
• Exposed InitializationOperation as public API.
• Added BuildTarget to ResourceManagerRuntimeData. This is used to check if the generated player content was built with the same build target as the player or the editor when entering play mode.
• Removed warnings generated from not finding the cached catalog hash files, which is not an error.
• Fixed bug where scenes were not unloading.
• Fixed GUI exception thrown in group inspector.
• Fixed error case where an asset (usually a bundle) was loaded multiple times as different types (object and AssetBundle).
• Fixed divide by zero bug when computing load percent of simulated asset bundles.
• AddressableAssetBuildResult.CreateResult now takes the settingsPath as a parameter to pass this to the result.
• Fix AssetReference GUI when the AssetReference is inside an array of classes, part of a SerializedObject, or private.
• Fix AssetReferenceSprite to properly support sprites (as opposed to Texture2D's).
• Fixed bug involving scenes being repeatedly added to the build scenes list.
• Removed deprecated and obsolete code. If you are upgrading from a very old version of Addressables, please update to 0.5.3-preview first.
• Removed the default MergeMode on LoadAssets calls to enforce explicit behavior.
• Added IAsyncOperation GetDownloadSize(object key) API to compute remaining data needed to load an asset
• Fixed assets being stuck in a read-only state in UI
• Unified asset moving API to clean up public interface
• Added PlayerVersion override to AddressableAssetSettings
• Ensure UI cannot show invalide assets (such as .cs files)
• Renamed Addressables.LoadAddtionalCatalogs to Addressables.LoadContentCatalog and now it takes the path of the catalog instead of the settings file
• Moved provider information from ResourceManagerRuntimeDate into ContentCatalogData
• Updating ResourceManager to be a non-static class
• Fixed bugs surrounding assets moving in or out of Resources (outside Addressables UI)
• Fixed the AssetReference dropdown to properly filter valid assets (no Resources and honoring type or label limitations).
• Fixed AssetReferences to handle assets inside folders marked as Addressable.
• Added attribute AssetReferenceUIRestriction to support user-created AssetReference restrictions (they are only enforced in UI, for dropdown and drag&drop)
• Changed addressables_content_state.bin to only build to the folder containing the AddressableAssetSettings object (Assets/AddressableAssetsData/ in most cases)
• Fixed issue where the wrong scene would sometimes be open post-build.

[0.5.3-preview] - 2018-12-19

• fixed upgrade bug from 0.4.x or lower to 0.5.x or higher. During upgrade, the "Packed Mode" option was removed from play mode. Now it's back and upgrades are safe from 0.4.x or from 0.5.x to 0.5.3

[0.5.2-preview] - 2018-12-14

• IMPORTANT CHANGE TO BUILDING
  • We have disabled automatic asset bundle building. That used to happen when you built the player, or entered play mode in "packed mode". This is no longer the case. You must now select "Build->Build Player Content" from the Addressables window, or call AddressableAssetSettings.BuildPlayerContent(). We did this because we determined that automatic building did not scale well at all for large projects.
• fixed regression loading local bundles
• Added Addressables.DownloadDependencies() interface
• fixes for Nintendo Switch support
• Fixed issues around referencing Addressables during an Awake() call
• Code refactor and naming convention fixes
• Cleaned up missing docs
• Content update now handles not having and groups marked as Static Content
• Fixed errors when browing for the addressables_content_state.bin and cancelling
• Moved addressables_content_state.bin to be generated into the addressables settings folder
• Changed some exceptions when releasing null bundles to warnings to handle the case of releasing a failed download operation
• Separated hash and crc options to allow them to be used independently in asset bundle loads.
• Use CRC in AssetBundle.LoadFromFileAsync calls if specified
• Always include AssetBundleRequestOptions for asset bundle locations

[0.4.8-preview] - 2018-10-22

• Added all referenced types in asset bundles to link.xml to prevent them from being stripped in IL2CPP builds

[0.4.7-preview] - 2018-10-20

• updated Scriptable Build Pipeline version in dependencies

[0.4.6-preview] - 2018-10-16

• MINIMUM RECOMMENDED VERSION - 2018.2.11+
  • We have re-enabled the addressables checkbox. Versions of 2018.2 older than the .11 release will work unless you attempt to view the Animation Import Settings inspector. If you do have animations you need to inspect, use .11+. If you do not, use any official release version of 2018.2.
• refactored the way IResourceProviders are initialized in the player - serialized data is constructed at runtime to control how the providers are configured
• added readonly custom inspector for AddressableAssetEntryCollection
• AssetReference now stores the loaded asset which can be accessed via the Asset property after LoadAsset completes. ReleaseAsset has been modified to not need the asset passed in (the old version is marked obsolete]
• fixed profiler details view not updating when a mouse drag is completed
• fixed null-ref when moving Resources to Addressables when there are no Resources
• blocked moving EditorSceneList within GUI
• fixed cap on address name length
• fixed workflows of marking Resources as addressable and moving an addressable into Resources.
• fixed issue where AssetReferenceDrawer did not mark scene as dirty when changed.
• added Hosting Services feature; provides extensible framework and implementation for serving packed content to player builds from the Editor
• replaced addressables buildscript with an interface based system. IDataBuilder class is now used to define builders of specific types of data. The Addressables settings object contains a collection of data builders and uses these to create player and play mode data. Users can implemented custom data builders to control the build process.
• replaced AssetGroupProcessors with a collection of AssetGroupSchema objects. The difference is that the schema objects only contain data and groups can have multiple schemas. The logic for processing groups now resides in the build script and uses the schemas as data sources and filters for how to build.
• Added Initialization objects that can be created during the build to run during addressables initialization
• Implemented Caching API initialization with initialization objects
• Changed some API and tests to work with 2019.x
• fixed how AssetReference's draw when within lists, arrays, or contained classes
• Fixed the workflow of scenes moving in and out of the Editor Build Settings Scene list.
• Removed "Preview" and added "Analyze".
  • The new system runs any rules it knows about.
  • Currently this is one rule that is manually set up in code. Future work will have additional rules, and expose the ability to create/add user- or project-specific rules
  • This process can be slow, as it runs most of a build to get accurate data.
  • Within the Analyze window there is a "fix" button that allows each rule to fix any issues if the rule knows how.
  • The current rule is a "check duplicate asset" rule. This looks for assets that are pulled into multiple asset bundles due to dependency calculations. The way it fixes things is to move all of those into a newly created group.
• Added option to toggle logging of all exceptions within the Resource Manager
• Refactored initialization of the addressable asset settings to prevent it getting into a bad state.

[0.3.5-preview] - 2018-09-05

• implemented content update workflow. Added a dropdown to the "Build" button on main window's toolbar.
  • "Build/Prepare for Content Update" will detect assets in locked bundles (bundles flagged as static, by default all local bundles).
  • "Build/Build for Content Update" will build assets with a catalog that is compatible with a previously released player.
  • "Build/Build Packed Data" will build in the same way entering play mode in PackedMode would.
  • implemented Clean Build. "Build/Clean/*" will clear out build caches.
• cleaned up streaming assets folder better after build
• moved asset group data into separate assets in order to better support version control

• default the first 2 converted groups to have StaticContent set to true
• UI Redesign
• Moved most data settings onto actual assets. AddressableAssetSettings and AddressableAssetGroup assets.
  • AddressableAssetSettings asset has "Send Profile Events", list of groups, labels, and profiles
  • AddressableAssetGroup assets have all data associated with that group (such as BuildPath)
• Made "preview" be a sub-section within the Addressables window.
• The "Default" group can now be set with a right-click in the Addressables window.
• Set play mode from "Mode" dropdown on main window's toolbar.
• Moved "Hierarchical Search" option onto magnifying glass of search bar. Removed now empty settings cog button.
• fixed issue when packing groups into seperate bundles generated duplicate asset bundle names, leading to an error being thrown during build
• added support for disabling the automatic initialization of the addressables system at runtime via a script define: ADDRESSABLES_DISABLE_AUTO_INITIALIZATION
• added API to create AssetReference from AddressableAssetSettings object in order to create an entry if it does not exist.
• moving resource profiler from the ResourceManager package to the Addressables package
• fixed bug where UnloadScene operation never entered Done state or called callback.
