I haven't tried Salamandra yet, but the folks on the one Part-15 group are into it, 2 or 3 members are testing or using it now, including someone from New Zealand on his LPFM run under low power rules.
Original Zara itself has been more neglected in recent years, though old versions work fine on older computer systems, there have been issues with Windows 10 and 11 apparently, but Zara has been slow to update, going by what users have posted.
That's where Salamandra comes in, it's made for these newer set of operating systems.
