v5.0.0

Tasking Manager v5.0 – FastAPI, Performance & More ⏩

We’re excited to announce the release of Tasking Manager v5.0, a major upgrade that modernizes the foundation of the platform. The highlight of this release is the migration to FastAPI, replacing the older Flask-based backend.

This migration was a big lift and it brings a more performant architecture to Tasking Manager, setting the stage for future innovation and scalability. Alongside it, we’ve fixed bugs, improved error handling, updated frontend components, and enhanced the CI/CD and infrastructure layers.

To validate the improvements, we ran a 5-minute load test comparing the legacy Flask API with the new FastAPI setup. Here’s what we found:

🟢 Requests handled:
~3,000 via Flask → ~7,500 via FastAPI
→ That’s 2.5x more capacity in the same time window.

🟢 Response time:
FastAPI cut the average response time nearly in half, and maintained much more stable performance throughout the test.

🟢 Success rate:
FastAPI retained a near-perfect success rate under higher load.

Big shoutout to @prabinoid and @kaditya97 for leading this work and the whole team for their contributions! 🙌
