I’m sad to hear that 
Unfortunately I can’t do anything about that anymore.
I dropped M$ Github after my last patches,since they wanted to force their 2FA bullshit on me,among other reasons.
I noticed before that support for FreeBSD and Solaris,which I also maintained,also broke and tried to send patches to the project maintainer by email.
Unfortunately I never received any reaction,maybe he doesn’t like directly receiving mails from contributors,or maybe it just landed in the spam folder and he never read it,I don’t know.
By that time,the port to Haiku still compiled successfully,but the Serenity codebase changes quickly so I guess that was only a matter of time.
Maybe I’ll get some patches merged by sending mails to other people who merged my stuff before on M$ Github,I don’t know.
I can’t promise anything,however,since they really don’t give a shit about libre communication channels and open standards and such,forcing M$ Github and Discord which are both proprietary walled-gardens that I’ll continue to avoid.
