• Various cosmetic enhancements and bug fixes for the user interface
• Fixed a bug where temperature isn't set properly for multi-material prints that use different printing temperatures

• Introduced initial support when Material Pods run out of filament
  • Element will try to use a new Material Pod (with the same color and material type) if the current material runs out
  • Run-out will only be handled when printing with long pieces, where run-out occurs after the Print Head is loaded
  • If there are no suitable Material Pods to use after running out, the print will be cancelled

• Improved UI for multi-color printing
• Improved UI for single color printing
• Added advanced network information, accessible through Element screen
• Improved firmware error logging
• Improved handling of errors during printing
• Fixed issue where filament was oozing from Print Head when pausing print
• Improved pausing / resuming process, fixing issues where print quality was affected
• Fixed issue where Print Head stops on top of the print resulting in poor print quality

• Element now supports individual Material Pod updates outside of the normal updater flow.
• Material Pods can be independently updated via Home > Materials > Details.
• A maximum of 2 simultaneous Material Pod updates are currently supported.
• Home screen layout has been readjusted to provide a more intuitive user flow by swapping the Materials and Settings icons.
• Fixed a UI bug where the temperature screen icons would shift on the page as the temperature changed.
• Fixed a bug that prevented 3rd Party Tag Initialization from working properly.
• Fixed various UI bugs on the print screen.

Common Changes

• Multi-Color Beta Feature Release
• Multi-Color support has now been enabled on all Array and Element devices.
• The UI while printing will shift between printing, pausing, and preparing screens while filament change is occurring; this is normal and will be polished in a future release.
• Note: Recommendation is to start with 2 colors and less than 100 transitions.
• Filament production length has now been tuned to waste less filament while printing a long piece of filament.
• This should reduce the amount of time densifying at the end of a print and result in less filament wasted.
• Clearing Filament Path and Cutting control screens have now changed to more clearly indicate when the job has completed.
• Changes have also been made to prevent a user from accidentally performing the same action again while the current actions is still being performed.
• Fixed a bug that prevented prints from starting due to an error while attempting to clear the filament path.
• Improved UI reliablility on device startup.

Element

• Fixed a bug that formatted error messages incorrectly, resulting in large text font for body text.
• Text should now be in proper font size and should be scrollable when the text body exceeds the size of the screen.
• Fixed a bug that caused the progress bar during a print to be incorrectly colored in various states.

Common Changes

• Updated the design of binary toggles

Element

• Fixed a bug where Element would occasionally display Material Pod's as 0-indexed
• Removed Restart button, and only support Power Off
• Added Printhead cooling fan control

Common Changes

• Added errors when attempting to print with an unsupported DAF version
• Fixed a bug where Offline users would see out of date files in the file viewer

Element

• Improved the UI for unloading a Material Pod
• Display advanced Material Pod details across all Material Pod screens
• Added more granular progress to Firmware Updating
• Improved error messages when Element is unable to automatically clear the filament path
• Display an error when an active Material Pod is disconnected during a print
• Improved Material Pod feeding reliability while printing

Element

• Improved microcontroller firmware reliability with green/blue firmware binaries
• Improved how the chamber is preheated before starting prints, removed Marlin's bed timeout of 20 minutes
• Fixed the reliability of Material Pod RFID reading for 1st and 3rd Party Spools
• Element Desktop now uses the power button
• Fixed a bug where offline Elements would allow the user to attempt an OTA firmware update
• Fixed a bug where Element would fail to start a print if the sensor values of the material pod were undefined

General Changes

• Improved the reliability of HostService dependency installation to be fully offline

General Changes

• Fixed a bug with network reporting where the IP address would also contain mac address information

Element

• Fixed a bug where Element would not accurately display its network status
• Updated the Wi-Fi connection flow to properly display connection errors, and fixed a bug where the connect button would be partially off the screen
• Updated the Print Head icon in the top bar
• Display 3rd party filament information in the materials portion of the expanded top bar

General Changes

• Sort files by date modified (most recent) when displaying them to the user

Element

• Fixed a bug where Element would not show the second updating screen, if the update was started through onboarding
• Fixed a bug in the uninstall printhead workflow, where uninstalling the printhead before the device expected would put it in a frozen state
