Breaking Changes

Version 1 Release Candidate:


  • New UI layout and design.
  • Dropbox tools re-introduced.
  • Performance counters.
  • New centralised help area provides richer content to the user.

Breaking Changes

  • We have migrated all DB, Web and Plugin services to new tools that have the same functionality. Please ensure that your services correctly migrated.
