Version 1.3.21 of xPilot is now available for download from the web site, or via the automatic update utility built into the pilot client (if you have the "Alpha" update channel selected in the settings).
The following items were changed, added or fixed in this version:
xPilot is now open-source
Client configuration file is now serialized in JSON. Upgrades from earlier versions will require reconfiguration.
Add volume knob control override option
Add option to change the aircraft label distance
Improve NetMQ message queuing
Update XPMP2 library
It is very important that you close X-Plane completely before installing xPilot. Failure to do so will prevent xPilot from being installed correctly.
This version marks the first Stable version of xPilot since its initial release. I did not anticipate keeping xPilot in beta/alpha for such an extended time, but I felt now was a good time to transition its development stage as to not keep tagging it as a "perpetual beta". I believe for the most part all of the major issues that caused crashes have now been addressed. If your X-Plane does crash and the log suggests that xPilot was the culprit, please file a bug report.
