Recent release notes
Fieldmesh G4 4.6.0 and G3 3.9.4, October 1, 2026
- Added: after a long outage, gateways now send the most recent readings first and backfill older ones behind them, so a clinician sees current values within a minute of reconnection.
- Fixed: a gateway re-homing to a neighbor could briefly report a device as offline.
- Changed: environmental sensor alarms at the local station now repeat every ten minutes until acknowledged.
Axon Sense 2 2.14.1, September 15, 2026
- Fixed: under rare conditions, a skin contact flag could be raised for one sample when the adhesive carrier was changed. No measurement data was affected. See advisory NXA-2026-006.
- Changed: battery estimate shown in Formcloud now accounts for the transmission schedule.
Nexa Edge 5.2.0, September 8, 2026
- Vehicle: a 12-lead ECG held while out of coverage is now resent within 5 seconds of signal returning, down from 30.
- Home: the status light now shows a distinct pattern when the hub is on battery backup.
How an update reaches a device
The same steps for every device family.
Published
A release is published to Formcloud with its notes, SBOM and signatures. Nothing installs yet.
Canary group
Your administrator chooses a small group to go first. Formcloud watches their error rates.
Staged rollout
Remaining groups follow on the schedule you set, inside the maintenance windows for each site.
Rollback if needed
Any group can return to its previous version, with a signed record of every transition.
Need to hold a version?
Some validated environments cannot take updates on our schedule. Formcloud can pin a group to a version for as long as that version is supported.
