Splinterlands.com recently announced new brawl fray setups here: https://peakd.com/hive-13323/@splinterlands/brawl-frays-riftwatchers-update
These changes will of course be visible as soon as the SPL API contains the new setups.
Additionally I want to shout out a big thank you to the TYC guild members who donated VOUCHERS for having access to the dashboard. That's super motivating, expect more great features to come.
