• Changed: The add function to properly disregard duplicate onewire devices so that they are not added to the white list.

• Implemented: A working remove functionality for the tool. This remove allows the tool to remove lines from the whitelist.txt regardless of their position also if the lines are terminated with CR+LF or just LF.
• Changed: The way the reset function works within the tool. Tool now uses systemctl to restart the onewire core application instead of the core application calling systemctl inside itself.
• Implemented: A command that returns the version of both the tool and the core application.
• Changed: The order in which tasks for onewire state machine are done. This is done to avoid missing devices that are already connected to the onewire bus. This is because when loading onewire devices that are already connected when S4 restarts, not all of the connected devices appear in the list of w1_master_slaves. Resulting in missing devices that are connected, but not loaded into the onewire application. Set up for udev is now done before loading devices found in w1_master_slaves.

• Changed: When S4 restarts and a onewire device that was already connected to the onewire bus is detected again; the original connection epoch doesn’t get overwritten or lost.
• Changed: Made it so that onewire information of the last connected device is saved differently so that the get_last function of the apx-onewire tool no longer depends on the onewire device existing in the white list.
• Changed: Core application now correctly lets the tool restart the application.
• Fixed: There was an issue that caused applications to get stuck in an infinite loop when the maximum number of onewire devices was reached.
• Fixed: Application was not able to search its internal list when the maximum number of onewire devices was reached.
