Widefleet 0.4.3 adds browser discovery and device login

Widefleet published v0.4.3 on October 23, 2026.

What changed

The official release identifies one user-facing workflow update: discover CLI destinations in the browser and use direct device login. This connects the browser's destination-selection workflow with the command-line side of the product.

The release also publishes guides for version 0.4.2. The preceding 0.4.2 release describes browser-policy verification stabilization, rather than a separate major capability launch, so this item groups the nearby product changes instead of treating documentation and preparation commits as additional launches.

What the notes do not establish

The release summary is brief. It does not specify a complete supported-provider list, credential-retention policy, migration procedure or performance measurements. Direct device login should not be interpreted as permission to connect every destination automatically; users still need to follow the product's authentication and authorization flow.

For implementation details, start with the linked official release and its discovery/login change. See the Widefleet hub for the existing product context.
