🚀 Improvements

• Upgraded to esp-idf 4.3 framework
• Improved startup time
• Coloring Analysis Item values based on age
• DHCP server on the internal network no longer serves a DNS server IP
• Added help links to web interface pages
• Better support for updating cached javascript and css when needed
• Better file system support for the UI flash partition
• Better error messages when a SD card isn't present or formatted

🐛 Bug Fixes

• Correctly increment the log number per log file type
• Ensure that multiple log marks in quick succession don't leak memory

Firmware v2.0.1

Improvements

• Some new and updated python scripts to work with log files (https://github.com/joshwardell/CANserver/tree/main/tools/python3_module)
• Added support for mDNS/Zeroconf/Bonjour discover of CANServer
  • You can now also access the CANServer's web interface by visiting http://canserver.local in your browser as well as using the ip address
  • Apps like tesLax and Scan My Tesla are adding support for discovery to make connecting to the CANServer easier
  • _http._tcp and _panda._udp services are now advertised.
  • There is a new option on the network screen to set the hostname of the CANServer for situations where multiple exist on the same network
• The Analysis screen now shows Analysis Item's age based on the last time an item was seen and decoded
• Release channels are now selectable from the Status screen. This allows switching between a development channel (for more frequent (but possibly unstable) development releases) or a release channel (for standard (but more stable) releases)
• If a heartbeat between a Panda client and the CANServer is missed and the CANServer disconnects the client the active filters will be saved and if the same client connects again the filters will be re-applied

Fixed

• Internal CAN frame for logging status has been updated so the log mode starts at 0 now. The DBC has been updated to reflect this.
• On single bus hardware the default busid will be correctly assigned
• Analysis Item signal offsets can now be correctly set as a decimal number
• When an error occurs while saving the script an error will be shown
• A memory leak when editing Analysis Items has been fixed
• CAN Interface B (on dual bus hardware) reliability fixes
