Summary Changelog

Lots of documentation changes and tweaks.
Add ability to log to syslog. Used only for certain new features at startup.
New FUSE message processing mode. Allow for a separation between threads which are reading messages and those processing messages. See process-thread-count option.
Added ability to pin threads to physical or logical cores automatically. Numerous algorithms provided. Makes it easier to limit mergerfs' compute footprint while maintaining concurrency. See pin-threads option.
Added ability to change mergerfs' scheduling priority (default has been -10). See scheduling-priority option.
Added ability for mergerfs on startup only to wait for all branches to become a filesystem other than the mountpoint's. This is not a full replacement for proper dependency management via systemd or similar systems but can help. See branches-mount-timeout option.
Try to catch and forbid adding the target mountpoint as a branch.
Added ability to set branch AND mergerfs readahead from within mergerfs at startup. Larger values may improve performance when using page caching in particular. See readahead option.
Added ability to lazily unmount the target mountpoint when started. This helps in live upgrades of mergerfs or instances where mount -a is run. This will allow the underlying instance of mergerfs to exit once it is no longer in use while the new instance is running on top of it.
Added new cache.files policy per-process. Used with cache.files.process-names it can define process comm names that will have page caching enabled when matched.
Reject all btrfs ioctl calls made to mergerfs.
Optimized FUSE message handling to reduce memory allocation. Same with some internal functions like read.
Removed need to set use_ino, nonempty, or allow_other. They should have been always enabled for proper functionality and compatibility. Setting them is a noop.
Removed all splice features. Over the years there has been little evidence the feature actually improved performance but did complicate the code quite a bit. The splice options are now noops.

Because it takes me a long time to cross compile all the non-x86 versions and sometimes they fail randomly. I uploaded ubuntu jammy armhf for 2.35.1.

arm64 build is also missing. Can you please upload it as well? Thanks always!
