The reason is one build tool which now requires SSE4.1 instruction support to run.
Rant
This instruction is ancient. According to multiple people on HackerNews they’re still using Opteron servers! No wonder the builds take so long, a cheap NUC would be faster.
I do donate to F-Droid on Liberapay. Adding donations from there and OpenCollective together they have something around ~3000$ in monthly donations.
That’s more than enough to either rent a few modern servers or save take the donations from a few months and get a new server.
They mention “Fixing build failures” on Liberapay, so they should definitely use some money for that.
Very true. Have you noticed it þey publish running costs, hosting, etc? How is þe donation use broken down?
