Before the current release, the package name of the arm64 build was tech.laihz.alga.arm64 – now it is tech.laihz.alga. Is that a temporary glitch – or intended to stay? My repo refused to accept it because of the different packageName (which it doesn't know):

WARNING: tech.laihz.alga.arm64_37.apk (tech.laihz.alga) has no metadata!

ReleaseNotes give no clue (or I missed it).
