# Changelog ## [2.2.3] - 2026-04-22 ### Added - Added `ExampleHigherComposer` sample under `Samples~/xApiComposers`. ### Changed - Improved tracking-related statement performance in `xApiStatement`. - Changed xAPI extension JSON serialization to preserve typed extension values. - Updated package version metadata. ### Fixed - Fixed incorrect context version handling in `ScenarioContextHook`. - Removed a broken runtime higher-composer example and stabilized `xApiSemanticComposer`. --- ## [2.2.2] - 2025-12-09 ### Added - Added `string version` to `ToDataStandardString()`, `ToJsonString()` and `ToCsvFormat()` in `xApiStatement`. - Added xAPI version selection to `Learning Record Store`. This selection will overwrite the default selection from `xApiRegistry`. ### Fixed - Fixed issue that `Learning Record Store` still sends statements by default with version `2.0.0`. ## [2.2.1] - 2025-12-04 ### Fixed - Fixed an issue where changing the xAPI version had no effect and it remained at `2.0.0`. The default is now `1.0.3` and version changes are applied correctly. - Removed various compiler warnings. --- ## [2.2.0] - 2025-10-13 ### Breaking Changes - Aktualisierung der `TinCan.dll` auf einen eigenen Fork: [TinCan.NET Fork](https://github.com/SGoerzen/TinCan.NET). - Unterstützung für xAPI 2.0 in Vorbereitung. - Hinzugefügte Unterstützung für Attachments. - Konsistentere URI-Verwendung. - Newtonsoft.Json von v8 auf v13 aktualisiert. - Umstellung auf strikte Typen in `xAPI.Extensions`. - Um diese zu nutzen, kopiere `xapi.config.json` über das Menü `OmiLAXR / Samples / Copy 'xapi.config.json'` und baue die `xAPI.Registry` neu auf. - Umbau des Statement Builders: `actor`, `Does` und `Activity` sind nun verpflichtend für gültige Statements. - Die `xAPI Platform String` wurde überarbeitet zum Format: `{UnityVersion}::{OmiLAXR.{Module}::{ComposerType}.{Composer}::{XRSDKVersion}` Beispiel: `UnityWindowsEditorv2022.3.62f2::OmiLAXR.xAPIv2.1.1::Other.FacialComposer::MetaXRv1.110.0` ### Added - **Eye Tracking**: - Neue Ereignisse wie `actor hovered/fixated/exited/saccaded/pursued vrObject`. - Austauschbare Logiken für die Erkennung. - [Vorschauvideo](https://youtu.be/nPS3H5GoF1Q) - **Facial Tracking**: - Neue Ereignisse: `actor changed face`, `actor expressed emotion`. - **xAPI Features**: - Unterstützung für xAPI Attachments. - Vorbereitung für xAPI Version 2.0.0 (Standard bleibt 1.0.3, umschaltbar in `xAPI Registry`). - Viele neue Definitionen in der Registry ([siehe Diff](https://gitlab.com/learntech-rwth/xapi/-/merge_requests/54/diffs)). - **UiComposer**: - Neues Ereignis: `"Pointed"` zur Interaktionserkennung. - Erfassung von Hover- und Druckdauer. - Zählung von Klicks während Hover und Gesamtanzahl an Klicks. - **AreaComposer**: - Neue Ereignisse: `"actor entered/exited area/room"`. - **StressComposer**: - Neue Ereignisse: `"actor stressed/relaxed/increased/decreased/updated stress"`. - **Menu Items**: - `OmiLAXR / xAPI / Copy 'xapi' folder from Samples` - `OmiLAXR / xAPI / Copy 'xAPI.Registry' folder from Samples` - `OmiLAXR / xAPI / Copy 'xapi.types.json' folder from Samples` - **Samples**: - Beispielkonfiguration: `xapi.types.json` (weitere Details in xAPI4Unity v2.2.1) ### Changed - Verbesserte Benutzerführung beim Erstellen von xAPI Statements (UX des Builders optimiert). --- ## [2.1.2] - 2025-08-25 ### Fixed - `StressLevelComposer` was missing its required `xApiComposer` class. - `WithRef()` and `WithDuration()` methods did not correctly apply reference or duration data to the resulting xAPI statement. --- ## [2.1.1] - 2025-08-17 ### Added - Handler in `InputSystemComposer` to generate xAPI-Statements for `OnReleasedAnyButton`. - Pipeline delegates for richer events. - License information added to each file. - XML `` documentation added to each file, field, and function, plus additional code comments. - All composers assigned to a composer group. ### Changed - Platform information format updated to `"OmiLAXR.{module}:{composerGroup}.{composerName}:v{version}:{Application.platform}"`. ### Fixed - `LearningRecordStore` now works on WebGL. - Platform version corrected. - Improved reliability of the `actor ended game` statement. ### Deprecated - None. ### Removed - None. ### Security - None. ## [2.1.0] - 2025-06-12 ### Added - **xApiStatement** - Added `.GetResultValue(string key)`, `.GetContextValue(string key)`, and `.GetExtensionValue(string key)` for value access. - Introduced `WithValue(xAPI_Extensions extensions)` and `GetValue(xAPI_Definition definition, T defaultValue = null)` to access and set values in activity, result, or context. - Implemented `ToCsvFormat(bool flatten)` for CSV conversion. - Added xAPI-compliant field methods: - `WithInteractionType(InteractionType)` - `WithCorrectResponses(params string[] | List)` - `WithRef(Guid guid)` - `WithDuration(TimeSpan duration)` - **Hooks** - Added support for timestamp pseudonymization and anonymization: - `ReferenceTimestampPseudonymizerHook`: Sets day to a reference date. - `TimestampPseudonymizerHook`: Applies a fixed date offset (default: 10 days). - `TimestampAnonymizerHook`: Applies a random date offset. - Platform metadata now includes composer and module info, e.g., `OmiLAXR.xAPI:TransformComposer:v2.1.0:OSXEditor`. - **Samples** - Added samples under `Window / Package Manager / OmiLAXR.xAPI / Samples`: - xAPI definition files and registry used in this version. - `PositionDataCsvEndpoint` as a lightweight example using `IEndpoint`. - `CsvFileExampleEndpoint` using `CsvFile` helper class. - **Other** - Added `LocalFileEndpoint` to Prefab. - Added duration information to teleport statements. ### Changed - Statement URI resolution moved to composers via `xApiRegistry` in `DataProvider`. - Renamed `xApiStatement.ActorRole` to `xApiStatement.Builder`. - Statement `id` is now generated client-side. - `StatementPrinter` is now enabled by default. - `LearningRecordStore` and `BasicAuthCredentialsFileLoader` are now disabled by default. - `Mouse` and `Keyboard` composers are now disabled by default. - Improved fallback behavior for missing xAPI registry entries. ### Fixed - **Critical**: Fixed an infinite loop when installing in large projects. - Endpoint was incorrectly started even when `enabled = false`. - General performance and compatibility improvements in the Unity Editor. ### Deprecated - Removed `IStatement.SetComposer(IComposer)` method. --- ## [2.0.18] - 2025-06-06 ### Changed - Renamed `EventTrackingBehaviour` to `ObjectlessTrackingBehaviour` to avoid confusion with `TrackingBehaviourEvent`. - **Need for action:** If any xAPI Tracking Behaviours extend `EventTrackingBehaviour`, rename them to `ObjectlessTrackingBehaviour`. - Made core xAPI Tracking Behaviours more extensible (`protected`, `virtual`). - Improved Unity Package Manager compatibility for Unity ≥2020.3.15f. --- ## [2.0.13 - 2.0.17] - 2025-05-21 ### Fixed - `LrsCredentialsLoader` no longer starts if it is disabled. --- ## [2.0.13 - 2.0.17] - 2025-05-21 ### Added - No xAPI-specific additions in this release. --- ## [2.0.11] - 2024-11-25 ### Added - `[Global Settings]` component added to the OmiLAXR prefab. - Support for path-based tracking names via `obj.GetTrackingName()` when enabled in `[Global Settings]`. ### Changed -
