See https://www.mozilla.org/en-US/firefox/62.0/releasenotes/ Fixes https://www.mozilla.org/en-US/security/advisories/mfsa2018-20/ * remove sndio patch from #1467882, merged upstream * update sandboxing patches to match what was commited in #1457092. Set MOZ_LOG=SandboxPledge:5 in the env if you want to debug pledge calls. * add aarch64 to ONLY_FOR_ARCHS. Probably doesnt build/package, but ppl interested may try to improve the situation.
