Good news everyone!
In the very beginning of November, we've released a new ExpertSDR3 1.0.1 Beta (link) and new Starter for ERS. In beta versions of the software we will work on bug fixes and improvement of existing functionality, there are no plans for new features at this stage of development.
MAKE SURE TO READ THE RELEASE NOTES before using the new ExpertSDR3 version.
You'll find the instruction on how to upgrade and downgrade the firmware on the FAQ page (link).
