Why You Should Update Immediately (And Not Wait)

The tag %21NEW%21 isn't just marketing fluff. Due to the discovery of the "LogoCrescent" vulnerability in older FOTA clients (v7.x and lower), delaying this update exposes your devices to potential man-in-the-middle attacks during firmware delivery. Stability in delta updates – Previous versions sometimes

1. Stability in delta updates – Previous versions sometimes failed on low-memory devices. v8.1.1 appears to handle incremental (delta) updates more reliably, reducing rollbacks by ~30%.
2. Better error reporting – New verbose logging for failed campaigns. No more generic “update failed” – you now get specific error codes (e.g., E-403 for storage, E-504 for network timeout).
3. Rollback speed – If an update bricks a device, automatic rollback to the last known good image is now ~40% faster than v8.0.x.
4. Security – Added support for signed manifests with Ed25519 (older versions only had RSA). This is a welcome hardening for production fleets.
