Release History
| Version | Changes | Urgency | Date |
|---|---|---|---|
| 2026.4.51 | Imported from npm (2026.4.51) | Low | 4/21/2026 |
| v2026.4.43 | # ✈️ Cabin Class Filtering — Search Business, First, Premium Economy **The biggest update yet.** You can now filter flights by cabin class across all 200+ connectors. ## What's New ### 🎯 Cabin Class Filtering Search for exactly the class you want — no more scrolling through economy results when you need business class. ```bash letsfg search LHR JFK 2026-06-15 --cabin C # business class letsfg search LHR JFK 2026-06-15 --cabin F # first class letsfg search LHR JFK 2026-06-1 | Medium | 4/12/2026 |
| v2026.4.36 | ## What's new **--mode fast** — search OTAs + key airlines in 20-40 seconds instead of 6+ minutes. Full local search fires all 200+ connectors which takes 6+ minutes on most machines. The new fast mode fires only ~25 high-coverage OTAs and key direct airlines, covering the entire world in 20-40 seconds: - **Global OTAs:** Kiwi, Skyscanner, Kayak, Momondo, Cheapflights, eDreams, Aviasales, Booking.com, Trip.com, Agoda, Hopper - **Regional OTAs:** Traveloka, Tiket (Asia), Ixigo, Cleartrip, Yatr | Medium | 4/9/2026 |
| v2026.4.35 | ## What's New ### Search by departure time You can now filter flights by departure time — find morning flights, afternoon departures, or red-eyes without scrolling through hundreds of results. **New parameters:** `departure_time_from` and `departure_time_to` (HH:MM format) ### CLI ```bash # Morning flights only letsfg search WAW BCN 2026-06-15 --departure-from 06:00 --departure-to 12:00 # Afternoon departures letsfg search LON NYC 2026-07-01 --departure-from 12:00 --departure- | Medium | 4/9/2026 |
| v2026.4.9 | - Fix MCP Registry description (max 100 chars) - Add glama.json for Glama.ai listing - Update mcpName to io.github.LetsFG/letsfg | Medium | 4/9/2026 |
| v2026.4.34 | ### Changed - Default search timeout increased from 60s to 90s - Ensures fast connectors (Kiwi, Skiplagged, Lufthansa Group API) always have time to return results before the global timeout fires ### Why - Long-haul routes like AMS→TYO query 100+ connectors - Many browser connectors queue behind the 6-slot semaphore - 90s gives API-only connectors plenty of time to complete ### Customize Set \LETSFG_SEARCH_TIMEOUT=120\ for even longer timeout if needed. | Medium | 4/9/2026 |
| v2026.4.33 | ### Fixed - **Global search timeout** — Searches now return results in 60s (configurable via \LETSFG_SEARCH_TIMEOUT\) instead of hanging 2+ minutes waiting for slow browser connectors - Fast connectors (Kiwi, Skiplagged, Lufthansa Group API) now return results immediately instead of being blocked by queued browser connectors ### How it works - Added \syncio.wait\ with timeout instead of \syncio.gather\ (which waits forever) - When timeout fires, pending browser connector tasks are cancelled | Medium | 4/9/2026 |
| v2026.4.32 | ## Emirates Connector Fix (#101) Fixed the Emirates connector DOM scraper for the new page format. ### Changes - Fixed date pattern regex to match new 'Mon 20 Apr' format (was 'Wed Apr 21') - Fixed price regex to handle decimal prices (EUR 332.37) - Fixed pre-processor to merge split currency/amount lines with decimals - RT highest-price filter now only applies to body-text fallback, not DOM results ### Install/Upgrade \\\ash pip install --upgrade letsfg \\\ ### Test Result \\\ letsfg searc | Medium | 4/9/2026 |
| v2026.4.8 | ## What's New - **Cabin class support**: Search by economy (M), premium economy (W), business (C), or first (F) - **False 'Direct' label fix**: Low-fidelity connector data now correctly shows 'Connecting' instead of falsely claiming direct flights - **20+ new airline display names**: French Bee, Corsair, Kenya Airways, Air Mauritius, Royal Air Maroc, Hong Kong Airlines, Porter, Turkmenistan Airlines, Flair, Hainan Airlines, Sichuan Airlines, Shenzhen Airlines, Shanghai Airlines, Xiamen Air, Roy | Medium | 4/9/2026 |
| v1.9.3 | fix(connectors): move airchina, itaairways, wego browsers off-screen. All three now launch with --window-position=-2400,-2400 so the headed Chrome window is never visible. Fixes #92. pip install --upgrade letsfg | Medium | 4/5/2026 |
| v1.9.2 | fix(wego): robust Cloudflare Turnstile bypass - page focus, human idle sim, token detection, JS API calls. CF passes in 2-3s consistently. Fixes #88. pip install --upgrade letsfg | Medium | 4/5/2026 |
| v1.7.0 | ## What's New in v1.7.0 ### Persistent Agent Store (Firestore Migration) - **Agent data now persists across deploys** — migrated from ephemeral local JSON file to Firestore. Previously, every Cloud Run deploy wiped all registered agents. (#86) - Added email index for O(1) duplicate lookups - File fallback preserved for local development ### Zero-Friction Onboarding (Auto-Registration) - **No manual registration required** — `LetsFG()` automatically registers and saves your API key on f | Medium | 4/3/2026 |
