Version 3.5.3

Compatible versions:

• RepRapFirmware 3.5.3
• DuetWebControl 3.5.3

Upgrade notes:

• If you are using a Raspberry Pi 5 and upgrade using apt, it may be necessary to restore the default config. To achieve this, run sudo rm /opt/dsf/conf/config.json after apt via SSH or using a Linux console. Without this step, you will get an error stating that the gpiochip device could not be opened. The underlying change came from a kernel change from Raspberry Pi, which brings the gpiochip numbering in line again with previous Raspberry Pi editions

API changes:

• Deprecated several methods due to upcoming changes in v3.6
• Added new preferred overloads for SetPluginData and PatchObjectModel

New features:

• M905 A parameter may be used to specify if the date and time shall be set via NTP

Bug fixes:

• Results from cancelled evaluation requests could be output
• Only resumable macros were aborted by DSF when a pause event was processed
• Fixed type of sensors.filamentMonitors[].calibrated
• Invoke internal "increment" codes asynchronously to fix spurious deadlocks
• M905 wasn't working any more due to missing permissions
• Fixed support for SSIDs with spaces
• Type of state.thisActive wasn't nullable
• Fixed support for M226/M600 preceding M98
• Fixed potential deadlock when deleting variables
• Fixed DWC startup issue in SBC mode caused by Chromium singleton lock
