TracCloud New Feature History
TracCloud receives frequent updates that are automatically applied to your instance. Some of these updates are smaller tweaks and improvements, while others bring entirely new features that may benefit your usage of the Trac System. The 'What's New?' tab above lists a handful of the most recent articles from this page, but you can find older articles right here as well. The 'Full Changelog' tab is where you can find a complete history of updates, including the smaller changes that end up without a dedicated article here.
If you're looking for a more in-depth guide on TracCloud as a whole rather than shorter update notes, take a look at our User Manual.
