v1.0.0 Unity-WebGL-SignalR

Breaking Changes

• Namespace: All plugin types are now in the UnityWebGLSignalR namespace. Add using UnityWebGLSignalR; to your scripts.
• Invoke API: The 10 Invoke overloads have been replaced with a single Invoke(string methodName, params object[] args) method. Existing call sites are source-compatible.
• Minimum Unity version: Legacy Emscripten compatibility code removed. Requires Unity 2021+ (tested on Unity 6).

Added

• SignalROptions class for configuring authentication, transport, timeouts, and other connection settings.
• TransportType and SignalRLogLevel enums for strongly-typed option values.
• Init(string url, SignalROptions options) overload for passing configuration options.
• IsConnected property to check connection state (Editor and WebGL).
• IDisposable implementation for proper cleanup of HubConnection resources.
• WithAutomaticReconnect() enabled by default on both Editor and WebGL paths.
• Custom retry delays via SignalROptions.RetryDelays.
• Assembly definition (UnityWebGLSignalR.asmdef) for proper project references.
• CORS support on the server for development mode.
• Unity EditMode tests (28) for options serialization and plugin logic.
• Unity PlayMode integration tests (5) for end-to-end client-server validation.
• GitHub Actions CI (ci.yml) for Unity EditMode tests, WebGL builds, and smoke tests on PRs.
• Automated release pipeline (release.yml): merging to main auto-determines version (PR label or patch increment), exports .unitypackage, tags, and creates a GitHub Release.
• Reusable test workflow (test.yml) used by CI pipeline.
• Composite action (setup-unity) for disk space cleanup, PowerShell install, SignalR DLLs, and Unity Library caching.
• ExportPackage editor script for CI-driven .unitypackage export with version from environment variable.
• Custom WebGL template (Assets/WebGLTemplates/SignalR/) with SignalR JS client <script> tag included automatically in all WebGL builds.
• Release pipeline auto-updates Server/wwwroot/ with fresh WebGL build on merge to main.
• WebGL smoke test (Playwright) — headless browser test verifying the jslib SignalR bridge end-to-end in CI.
• Release dry-run mode via workflow_dispatch.

Fixed

• Memory leak: JavaScript invokeCallback allocated buffers via _malloc but never called _free. Every callback invocation leaked memory.
• Falsy argument bug: JavaScript InvokeJs used truthiness checks (if (arg1 && arg2)) which failed for empty strings, "0", and "false". Now uses !== 0 null-pointer check with a NULL_SENTINEL for marshaling null arguments through the C#/JS boundary.
• Null handler crash: WebGL HandlerCallback methods did not check TryGetValue results, causing NullReferenceException for unregistered methods.
• Async void crash: Editor Invoke methods were async void with no try/catch. Exceptions from InvokeAsync would crash silently.
• Duplicate On() crash: Calling On() twice for the same method name threw ArgumentException from Dictionary.Add. Now uses indexer assignment.
• Reconnecting NRE: OnConnectionReconnectingEvent accessed exception.Message without null check (fixed in both Editor and jslib paths).
• Event handler race: Connection event handlers were subscribed after StartAsync completed, creating a window where close events could be missed. Moved to Init().
• WebGL Dispose() leak: Static types and handlers dictionaries were never cleared on dispose, leaking handler registrations across sessions.

Changed

• On<T> Editor overloads simplified to pass handler directly to connection.On().
• JavaScript bridge (SignalR.jslib) reduced from 240 to ~170 lines by replacing duplicated if/else chains with loops.
• OnJs handler slots (handlerCallback1-8) replaced with per-registration closure capture.
• signalr.ps1 switched from nuget CLI to dotnet restore — removes the NuGet CLI dependency.
• TestScript updated to use [SerializeField] instead of GameObject.Find.
• Instance replacement now logs a warning.
• Removed version.txt — version now derived from git tags.
