v0.3.9

This release fixes the build for the soon to be released 6.9 kernel.

Support is tentatively added for the new 0x80 incompatible volume
feature, which appears simple enough so far and isn't causing any
problems.

A console warning that showed up during compressed file reads on recent
kernels is now fixed.

Support is improved for tiny filesystems of under 100 MiB, though they
remain awkward to test due to fragmentation issues.

The behaviour of apfs_modified_by is tweaked to better match the
official driver.

Free queues should now be much harder to fill up. The most important
change here is that files are now deleted across multiple transactions.
