Full Changelog: v0.2.0...v0.3.0

v0.2.0 — Local MITM Proxy

What's New

Local MITM Proxy Engine

• CA lifecycle: RSA 4096 root CA + ECDSA P-256 leaf certs with auto-generation, expiry detection, and secure key storage
• CONNECT proxy: Per-domain TLS terminators with static certs, bidirectional data relay
• Trace capture: HTTP/1.1 request/response parsing, Content-Length and chunked-terminator completion detection
• SSE reassembly: Anthropic and OpenAI streaming format support with token extraction
• Cert cache: LRU cache (100 domains, 25-day TTL), sub-millisecond cached lookups

UI Improvements

• Bold tray icon (funnel + signal waves) with retina @2x support
• Icon-only menu bar (no text)
• Live trace counter and proxy status in tray menu

Developer Experience

• AGENTS.md updated with Bun TLS limitations, working proxy patterns, and rollback instructions

Test Results (22/22 passing)

• SSE streaming with mock Anthropic server
• Chunked transfer decoding (basic, JSON, multi-chunk)
• Cert cache LRU eviction at 100+ domains
• CA expiry and auto-regeneration with chain validation
• E2E proxy trace capture against live api.anthropic.com

v0.1.0 — Phase 0: ElectroBun Scaffold

Phase 0: ElectroBun Scaffold

Initial release — desktop app skeleton with:

• Menu bar tray app with capture toggle, per-provider enable/disable, status display
• Swift FFI bridge — universal dylib (arm64 + x86_64) with @_cdecl exports for version, system info, firewall/keychain capability checks
• Main window — dark theme status dashboard
• 8 AI providers pre-configured (Anthropic, OpenAI, Google AI, Mistral, Cohere, Groq, DeepSeek, xAI)
• GitHub Actions CI — two-stage pipeline (Swift dylib → ElectroBun app)

This is the foundation scaffold. No actual traffic interception yet — that comes in Phase 1.
