JA3Proxy 0.5.1 አውርድ

What's Changed
Features
- Added hot-reloadable TLS fingerprint configuration via -fingerprint-config.
- Supports loading client and version from a JSON file.
- New HTTPS CONNECT connections use the latest loaded fingerprint.
- Existing tunnels continue using the fingerprint they were opened with.
- Fixed CONNECT response handling for clients such as ffprobe.
- Aligned ALPN behavior between client-side and upstream TLS connections.
- Avoided mutating Go's default HTTP transport.
- Passed HTTP transport traffic through the configured upstream dialer.
Improvements
- Added SOCKS5 upstream proxy handling improvements.
- Moved CLI source into cmd/ja3proxy.
- Changed default generated CA paths to:
- credentials/cert.pem
- credentials/key.pem
- Updated Docker runtime paths and Docker context ignores.
- Updated Makefile output paths so release binaries are written under bin/.
- Expanded README with usage, Docker, certificate, fingerprint, and development docs.
Testing
- Added end-to-end proxy tests.
- Added JA3 fingerprint verification coverage.
- Added unit tests for proxy handlers, MITM CONNECT flow, upstream dialer construction, custom TLS wrapping, certificate handling, debug writer behavior, and
edge cases.
Dependencies and CI
- Updated github.com/refraction-networking/utls from v1.6.7 to v1.8.2.
- Updated github.com/cloudflare/cfssl from v1.6.4 to v1.6.5.

Upgrade Notes
The default certificate files are now stored under credentials/ instead of the repository root. If you previously relied on cert.pem and key.pem in the
current directory, either move them to credentials/cert.pem and credentials/key.pem, or pass explicit paths with -cert and -key.
