New features

• lup (least used percentage) policy: selects the branch with the lowest used space percentage.
• mount.mergerfs now includes the -n flag to support mounting without updating /etc/mtab.

Improvements

• Better lock management and behavior with open files. Reduction of contention.
• Custom filename dedup strategy improving directory reading performance
• Pre-calculate part of the file inode within readdir significantly reducing cost of overall calculation.
• Replace sched_yield with nanosleep for improved scheduling of contention situations.
• improved stat auto cache fingerprinting to reduce stale reads.

Behavior changes

• credential handling reworked to be compatible with chroot and idmap. removed ability to disable default_permissions option as a result as mergerfs now requires the kernel to manage entitlements.
• broken mounts with ENOTCONN (common due to crashed FUSE instances) are automatically unmounted if possible on start instead of hard erroring. (mostly useful while developing).
• fusermount3 will be used if available and other options missing.
• remember-nodes option is deprecated and the feature removed. There is now only never-forget-nodes behavior. Any non-zero value in remember-nodes will enable never-forget-nodes. It was removed because time based really didn't save much memory and complicated the code. Doing this also reduced the size of each node helping offset increased node count.

Bug fixes

• fix race condition between runtime changing of branches and certain requests.
• rmdir no longer returns success if any rmdir call returns ENOTEMPTY.
• Invalid policy names are properly rejected.
• statfs calculation could theoretically have overflowed with impossibly large branch values.
• Fixed readlink buffer size management. The size does not include a nul terminating value.
• Minor calculation bugs in copy_file_range and futimens.
• moveonenospc no longer crashes when all destination branches are rejected. Returns ENOSPC.
• Better / more proper error calculations in a number of functions.
• rare ioctl call crash fixed

Hardening

• many "the kernel should never do this bug just in case" enhancements
