smart-mcp-proxy/mcpproxy-go v0.35.0 on GitHub

This release introduces actor-owned usage tracking, registry management improvements, and critical stability fixes for runtime operations.

New Features

Usage Analytics & Persistence: Implemented actor-owned usage aggregates with full persistence layer, enabling detailed tracking of resource consumption per actor
Pre-truncation Byte Capture: Activity records now capture original request/response byte counts before any truncation occurs, improving usage analytics accuracy
Registry Upstream Management: Added easy upstream server addition through new core registry operations with CLI MVP support (US2)

Bug Fixes

Runtime Stability: Fixed critical issue where in-flight reconcile actions weren't properly drained before client disconnect, preventing potential data loss and race conditions (MCP-783)
Upstream Configuration: Resolved data race in client.Config between DiscoverTools and SetConfig operations that could cause configuration corruption (MCP-770)
macOS Personal Edition: Disabled automatic text substitutions in the tray app that were interfering with user input (#538)

Documentation

Updated Homebrew installation instructions to reflect current setup process
Added Glass Cockpit specification and agent-instruction bundle documentation
