I don't have access to an ARM64 machine (other than a mobile device) myself, so I can't test anything on that platform. I did not *expect* there to be any issues, but I am not surprised that there are. I should have done a basic smoke test on x86, though. --=20 Sincerely, Demi Marie Obenour (she/her/hers) Invisible Things Lab --9QU2mazQtCSQEbPT Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEdodNnxM2uiJZBxxxsoi1X/+cIsEFAmLFOUYACgkQsoi1X/+c IsF5ww/+MpL+dLCGIcFZxLwuSkevBR0p89ufuOJ1heCxbyY7CiPbfTjhNGyrD+bw SPBIACbxKIatJu3Mqlb7CfLpQHCF/fgcpe/6XOynDEblc1DGDpaAoie0vVDYRYwK l97nh19F6wy/xlRESGPaFRW2aAfPz4lnL7udYfs/fIM72pb3BWUpThGahe6vucDt aQtVFe7yBBjtZ3KfLSpCOohsX1LfTIpUH8aUrMF/ph6fSEqmmgqzmMrEj57T9Glp xslBTW50HF8CdyTSUNgu0UcApfr+FuROqdXjyMw5N29cdz+ep2YIZ97oULu77DX/ xwgQrE6IL7tnHrIkBliHD1WytZ4iOOCLIP0fb4X1rmrNCxHJIerI3VceC2uJ4HG4 TD7x8HitF7ie2RVuKtojIMkmwesb9+zqRzUt22Sj8CZHOc1blAnxaH7rJo/VUldL EOQQLkBj/xMXU+c9Jf7q0NK8lyn9WXU+QkPK8Ov/mjyRim/M9qLPBuyJ5NbefJmK 713aeZn+ImfZNt1wd9XMdpyEvOaEP45oT0KjcmDyOShG+ESTzhVUab8hZ3BMejMx 5aspG8WfL1GVj7kZqi/JOa8CYzjfz6niww/bsnRwzMpqAi8y9hWV4riak5TaQHW8 AzOq63MctQycywQX6/Buks9qO3EMYhJzbDuOwbg1Nh+LyWBpJrg= =jJsH -----END PGP SIGNATURE----- --9QU2mazQtCSQEbPT--
