This release only adds support for ARM64 Linux systems. No changes to the binary source implementation or API have been made since v0.5.3.
I'm testing on a Raspberry Pi 4 with beta version 64-bit operating system, and, despite having a rather long list of platform tags for wheels that the system _should_ be compatible with, `pip` on this system only seems to accept `none-any` wheels. This doesn't prevent us from offering a `none-any` wheel that is compatible with 64-bit Raspberry Pi OS, but it does force users to use the non-specific `none-any` wheel, which includes _all_ platform binaries we support, significantly increasing the size of download and installation for the package. (The difference is _significant_, as a percentage of package size with only ARM64 binary, but the entire `none-any` wheel file is still only ~8 MB.)
Note also that the ARM64 binary here is theoretically OpenCL-ready, without modification, for systems with one or more ICDs, as are all binaries in PyQrack.
