v0.88.0 - sessions, binary websockets & templating ergonomics

Highlights

• First-party sessions — signed-cookie sessions via request.session (#945, #1411)
• Binary WebSocket frames — binary frames are forwarded to your message handler (#1148, #1416)
• render() templating shortcut — render a local templates/ folder without constructing JinjaTemplate by hand; engine-agnostic with Jinja2 as the default (#1223, #1418)
• Hot reload fixed for module launches — python -m ... now relaunches correctly on file changes (#654, #1417)
• Batch of quick-win fixes (#1415) — resolves #1099, #1147, #1273, #495, #470, #1192
• Docs — single-page cheatsheet (#1062, #1414) and a bilingual (EN/ZH) templating refresh
• CI — lint no longer builds the Rust extension (#1413)

v0.87.0 - sub-routers, middleware chains & binary streaming

Sub-routers grow up, middleware can be chained, and streaming handles binary + async data correctly.

✨ Features

• Modern SubRouter syntax with nested-prefix fixes and cleanups (#1404)
• Async authenticate() and automatic SubRouter auth-handler inheritance — sub-routers can configure their own auth or inherit the parent app's (#1407)
• Multiple middlewares per route (middleware chains) (#1405)
• Consolidated OpenAPI/Swagger fixes with per-route documentation flags (#1403)

🐛 Fixes

• StreamingResponse now supports bytes (binary downloads / application/octet-stream) and async DB access inside generators; generator errors now propagate to the logs instead of silently truncating the stream (#1412 — closes #1236, #1219)
• Cast bare before_request returns and handle OPTIONS under static mounts (#1409 — fixes #793, #1130)

📚 Docs

• Document catch-all / wildcard (*path) routes (#1410)

Full Changelog: v0.86.0...v0.87.0

v0.86.0 - smoother request & response ergonomics

A round of quality-of-life fixes and FastAPI-parity papercuts, consolidated in #1399.

Fixes & features

• request.json() now parses both str and bytes bodies — previously a bytes body raised a raw error (#1335)
• Path-param warning no longer fires when handlers read params via request / request.path_params (#1336)
• Response(body=...) alias for the confusingly-named description= — both work, and headers is now optional (#1337)
• New request type aliases RequestMethod, RequestBody, RequestURL, importable from robyn and robyn.types (#1077)

Docs

• Documented the new type aliases and the Response body= alias (English + 中文)

Big thanks to @ahmadmahmoody, whose fixes were consolidated (with authorship preserved) into this release. 🙏
