qpwgraph v0.5.2 - A High-Summer'23 Release

Not much to say in the heat of the season: consider the update as a refreshment. Though please, if still running any pre-v0.5 installment, an upgrade is mandatory, immediately, better say now!

qpwgraph v0.5.2 (high-summer'23) is out!


  • Ctrl+left or middle-button click-dragging for panning, is now a lot smoother, hopefully.
  • Click-dragging with the mouse middle-button is for panning only, not to start a selection anymore.
  • Add Ctrl+Q to Quit action.

qpwgraph v0.5.1 - A Summer'23 Hot-Fix Release

Hi again!
On the next day comes a fiery hot-fix: again, everyone is strongly advised to update ASAP! Especially if using any of the previous ill-fated v0.4.x series (or yesterday's v0.5.0, which should be promptly ditched to the trash bin :)).

qpwgraph v0.5.1 (summer'23 hot-fix) is released!

Change-log (including the previous release):

  • Fixed segfault on initialization that was affecting Qt5 builds.
  • Completely refactored the internal PipeWire node registry logic, just to have unique node names, as seen fit to purpose to solve an old undefined behavior to positioning and Patchbay persistence of multiple nodes with the very same and exact name.
  • Fixed the main PipeWire registry thread-safety, into a two-level critical section, hopefully preventing the race-conditions that are the suspected cause to some rare crashes.
