Release History

Track the evolution of the Asteri web server.

v2.2.2 (Current)

May 19, 2026

This is a landmark release that transforms Asteri from a high-performance web server into a fully enterprise-grade production framework. It delivers native HTTP/3, a C-Extension performance core, integrated telemetry, and a fully enforced static quality pipeline.

🚀 New Features

Native HTTP/3 (QUIC): Full HTTP/3 protocol support with QPACK header compression/decompression, QUIC packet framing, and integrated handshake handling.
⚡ C-Extension Parsing Core: Rewrote the HTTP/1.1 and uWSGI parsers as a native C-Extension (asteri.fastparser) for blazing-fast zero-copy buffer throughput. Includes seamless Pure-Python fallback.
Prometheus & OpenTelemetry Metrics: Native Prometheus 0.0.4-compliant /metrics endpoint. Metrics are synchronized across all worker processes via the Stash IPC server.
Automated PyPI Publishing: Secure, passwordless OIDC Trusted Publishing workflow via GitHub Actions — releases to PyPI automatically on every v*.*.* git tag push.

🛡️ Quality & CI/CD

Mypy Static Typing Enforced: All 41 source files are 100% type-annotated and verified. Zero runtime type-errors guaranteed.
Ruff Static Analysis: Cleaned up 100+ E701 and E722 violations. Entire codebase is now strictly PEP-8 compliant.
Black Formatting: Global PEP-8 auto-formatting applied across all 47 Python files.
CI Pipeline Hardened: GitHub Actions now enforces ruff check and mypy on every push before tests run.

✅ Testing

87/87 Unit Tests passing.
40/40 CLI Regression Scenarios verified via test_asteri_cli.sh.

v1.2.2

May 17, 2026

This release added massive event loop integrations (Tornado), unified visual dashboards, robust ASGI fixes, and comprehensive regression test suites.

🚀 New Features

Native Tornado Integration: Added tornado and gtornado worker classes for high-performance non-blocking async loops.
Unified Premium Status Dashboard: Created a gorgeous, centralized status page builder in glassmorphism UI for all worker classes.
Robust Intercept Middleware: Automated dashboard/log routing inside Tornado workers using transparent WSGI wrapper middlewares.
Exhaustive Regression Suite: Upgraded the CLI test framework to cover 100% of the 36+ CLI options and system arguments.

🐛 Bug Fixes

FastAPI/Flask ASGI Compatibility: Fixed the ASGI __call__ calling convention parameter count bug in modern frameworks.
Zero Orphaned Workers: Fixed potential zombie process hazards during abrupt shutdowns.
CI/CD Integration: Expanded GitHub Actions workflow to include full discover-based unit tests.

v1.2.1

May 16, 2026

This is a major stability and architectural update, addressing critical bugs discovered during production stress testing.

🚀 New Features

Output Capture Support: Added --capture-output to redirect stdout and stderr to error log files.
Dynamic Environment: Automated resolution of SERVER_NAME and SERVER_PORT via listener socket metadata.
Enhanced GThread: Better thread pool management with explicit --threads support.
Streaming Body: Implemented WSGIInput for efficient, memory-safe body streaming of large requests.

🐛 Bug Fixes

Arbiter: Fixed a critical bug where the master process exited before reaping worker processes.
HTTP/2: Resolved connection preface data loss during the H2 handshake.
uWSGI: Fixed parsing failures for packets exceeding 4KB.
Signal Handling: Improved SIGQUIT and SIGTERM behavior for graceful shutdowns.
Security: Added safety limits for large headers (up to 32KB).
