Release notes.

What changed in each Sentinel Flash build. Hardware tested means a real GHL device completed that work. Software checked means the build and its checks passed, but it has not yet run on a device. Sentinel Flash is an independent project, not affiliated with GHL.

Known limits

Pause dosing yourself before updating a device on a doser's PAB chain. Sentinel Flash does not pause it for you: an earlier automatic pause showed pumps as off while they kept dosing, so it was removed.
Relay Firmware is unofficial modified firmware. Installing GHL Firmware removes it.
The controller's USB bootloader sometimes does not connect on the first try. In the logged cases the update stopped before anything was erased.
The automatic bridge rollback after a failed wireless update has not been tested by forcing a failure.
A complete update, switch and recovery run with three controllers on one hub has not been confirmed.
KH Director: my unit will not enter its bootloader, so I cannot confirm updating it or using it as a relay. A Doser EXT update has completed with a KH Director connected on the chain.
Mitras LX7 still needs bench validation.
Version 0.10.7 still includes GHL flash helper files: a modified m_flash.9b560r for ProfiLux 4 updates and unmodified copies as a fallback. A version with no GHL code is coming soon.

0.10.7

November 4, 2026

Software checked

Explains Relay Firmware directly below the firmware choice. GHL Firmware stays first and selected by default.
Text only. The update process is unchanged.

0.10.4 to 0.10.6

November 4, 2026

Software checked

Moves the ProfiLux 4 restart test, PAB handshake probe and Parameter list into a new Experimental area, each with an explanation.
The handshake probe gets its own device selector.
A missing parameter definition now takes you to the Parameter list card.
These are placement and explanation changes.

0.10.3

November 4, 2026

Software checked

Unplugged controllers disappear from the list, and another connected controller is selected while idle. A reconnected controller does not take over the selection.
ProfiLux 4 updates compare settings and saved probe calibration, then restore them together if they differ.
Portable settings and calibration backups can be exported and imported.
New recovery option for a controller already in its USB bootloader, limited to one whose identity and backup match.
PAB versions are marked unverified after an assignment change.
New offline firmware library import and one-file support report.

0.9.4 to 0.10.0

November 2026

Hardware tested: PAB Add, Remove, Add

Adds PAB Add and Remove, with the full device list checked. A logged Add, Remove, Add run kept the other device's assignment.
Identifies unassigned PAB devices from their serial numbers. Full model coverage is still being tested.
Improves USB cleanup and retries after a disconnect. Reliable unplug and reconnect is still being tested.

0.9.0 to 0.9.3

November 2026

Hardware tested: hub detection and selection

Adds powered USB 2.0 hubs, with up to three controllers on one bridge and one active at a time.
Device cards show model, serial, firmware and port.
PAB controls are turned off for ProfiLux Mini WiFi and Light WiFi.

0.8

November 2026

Hardware tested: ProfiLux 4 on 7.53

Adds ProfiLux 4. A stock 7.53 reinstall matched on a full 1 MiB flash readback, and the controller restarted by software.
A ProfiLux 4 updated a Doser EXT to stock 1.62 on its PAB chain with a KH Director connected.
Online bridge update confirmed: published 0.8.11 ran on the test bridge with a matching checksum.
Adds a browser-based USB installer for the bridge. Its first bench install is still unconfirmed.

0.7

November 2026

See 0.8 for hardware results

Adds the tabbed interface.
Adds online bridge updates.

0.6

October 31 to November 2, 2026

Hardware tested: Light, Doser EXT, wireless bridge update

Adds wireless bridge updates and automatic page reload.

Doser EXT 1.62 to 1.60 to 1.62 completed through PAB.
Adds recovery tools for interrupted PAB transfers and bulk deletion of old backups.

Before 0.6
