We used September to improve time tracking and several /UX and performance related topics.
Time tracking:
You can now track time based on the card progress, when a card moves to completed, the spent time can be calculated based on the start and end dates of the cards.
UI/UX improvements:
Improved the board layout to make cards more clear.
Improved the detail panel on the right-hand site to make it easier to read the different attributes.
Improved the attribute pickers to make it easier to select the attributes (for example to add 1 week of effort).
Performance improvements:
Gantt auto updates when cards have empty checklists.
