Released: August 11, 2025

What’s Changed

• New Server Architecture with SignalR – Introduced a dedicated MCP server. Added a base hub and RemoteApp hub to manage SignalR connections, tool/resource updates, and application tool events; implemented McpServerService for server lifecycle, routing for resource and tool calls, a console logging provider, and command‑line argument parsing.

• Cross‑Platform Build Scripts – Removed obsolete build configurations and added PowerShell/Bash scripts to build self‑contained executables across Windows, macOS, and Linux.

• Core Structure & Library Migration – Refactored the project’s core folder structure and migrated the Unity‑MCP‑Common module from a precompiled DLL to runtime C# source files, enabling source‑level integration and easier development.

• Editor & Build Simplification – Removed all server build and .NET SDK management logic from Unity editor scripts to focus on client. Deleted outdated preprocessor directives and redundant #pragma warning disables.

• Server Binary Management – Added automatic download and version validation of server binaries with improved logging and error handling, enhanced version validation tests with fallback paths.

• CI/CD Enhancements – Updated GitHub workflows to use a unified test configuration introduced zip archive creation for build outputs and streamlined deployment workflows.

• Multi‑Platform Build Support – Enhanced build scripts and project configuration for multi‑platform support added Directory.Build.props, updated .gitignore, and unified output paths for consistency.

• Configuration & Logging Refactors – Refactored JSON configuration handling to return JsonNode and updated config methods for clearer defaults. Improved logging in connection management and build scripts.

• Miscellaneous Clean‑ups & Fixes – Fixed compilation errors across new projects. Removed temporary directory creation code. Deleted the unused ReflectorNet.dll binary. Bumped package version to 0.14.0.
