What's new in Sequence Diagram

Version 1.8.4:
  • Adds support for async signal arrow heads (see Help documentation, page 8)
  • You can now tap interaction frame divider lines, to highlight the associated declaration in the diagram text
  • Adds support for Interaction Frame dividers using 3 dashes (---), which render a dashed line between signals in an Interaction Frame (see "New with Example [OPT+CMD+N]")
  • Minor improvements to Participant HUD
  • Adds “Shows Participant HUD” menu option, to present the participants in an overlay, when the topmost participants are no longer entirely visible
  • Fixes a rare crash seen when the syntax highlights are applied
  • Fixes a defect where interaction frames containing only signals to self, would render incorrectly
  • Fixes a defect where reversed signals would always render with a solid signal line
  • Updates acknowledgments
  • Removing Crashlytics
Other recent enhancements:
  • Updated to use Microsoft AppCenter for crash reporting and analytics
  • Adds support for copying the diagram into the paste buffer as an SVG
  • Adds “#style-reset” keyword, to resume default styling for elements that follow
  • Adds an indicator beside auto-completion suggestions, do distinguish keywords from user strings
  • Adds support for placing self-signal message label on right OR left of signal arrow

  • Minor improvements to auto-completion behaviour
  • Adds support for custom vertical spacing above Dividers, Interaction Frames, Notes and Signals (see Help documentation, page 25)
  • Adds support for dividers with no label
  • Fixes a defect where having a lifeline destruction marker on the left could cause a signal to not be rendered
