Changelog

This release contains a significant performance improvement by reduction of CPU overhead. Previously, topic update events were unnecessarily propagated to every single widget that was subscribed to any topic at all, which caused a huge amount thread contention and unnecessarily wasted CPU cycles in the logical thread.

Previously, on an i5-2520M, 35 Double-based widgets updating every cycle caused an i5-2520M to shoot up to nearly 20% CPU usage, and a T8100 hovered over 50% (single-core). Now, this same test results in just 5% usage at peak!

Additionally, subscription overhead has been reduced, meaning app startup is now up to 4x faster.

Bug Fixes

  • The Connection Mode selection was nonfunctional.
  • The Camera widget's Reconnect button was grayed out despite still being functional.
  • Some miscellaneous issues with coloration were addressed.
  • The Graphide menu transitions were inconsistent and often too slow.
  • A memory leak would occur during theme reload.
  • The Errors widget had a misalignment between icons and text.
