New features included in this release:
Fixed a bug that would not allow the user to approve the deployment settings. The receiver would keep asking the user to approve the settings even after just doing so and the deployment system would remain in a NO-GO status no matter how many times the user approved the settings.
This bug would only show up if the pyro battery type in the pyro board was already set to LiPo when the receiver was turned on. The pyro battery type was being checked when the deployment settings were being checked. This should not happen. The reason it was, is because the pyro battery type setting used to be part of the deployment settings a long long time ago. When that was changed, there was a fragment of code accidentally left in the deployment settings process that should not be there. That code fragment was checking the pyro battery type. An easy work around for this problem was to go into the battery type menu and change the type to 9V and then change it back to LiPo. That has the effect of telling the receiver the actual battery type so that the deployment settings process is happy. Otherwise, the deployment settings process just assumes the battery type is 9V by default. Which is why this bug only showed up when the battery type had been previously set to LiPo. At any rate, the whole problem has been fixed with this release.
