There are basically two contributors. csagan5 is the maintainer and then there's uazo.
Reading between the lines it seems csagan5 is having life interfering with Bromite. They made a draft PR in January for v109, surfaced in May to say they'd update it to some later version and then went below the radar again.[0]
uazo has been releasing up-to-date test builds at github.com/uazo/bromite-buildt… where the latest is v115 and says "Please note: this is the last release, the next one will be in github.com/uazo/cromite"[1]
