2.19.3

October 10th, 2024

This release focuses on stability and performance improvements. We usually label these 'internal improvements' since most of you won't be affected or notice the change, but some of the fixes include:

  • Improved memory management to prevent the UI from occasionally restarting
  • Mitigation of some errors where the UI would appear to freeze
  • Avoiding recording multiple 'trip reports' if the journey included short stops
  • Better handling of some battery information for boats equipped with Polestar batteries
  • Improved error messages and instructions on software updates
  • Faster start-up time

As always, please update to this latest version of the Candela C-8 UI to make sure your boat is using the latest features and improvements. There are certainly still issues we haven't fixed yet, but we are working hard to get to them.

P.S. The Candela P-12 Shuttle will soon enter traffic in public transportation in Stockholm. Get in touch if you want a custom P-12 to complement your C-8!
