2.53.3 contains bugfixes and improvements.
On Linux, allow syncing the xattrs where POSIX draft ACLS are
stored, which enables syncing the ACL info. (Note that this does
not enable syncing ACLs with the -acl switch, and does not
enable syncing ACLs between other systems and Linux. See the
manual.)
Improved ETA calculation and sync speed display in text UI.
Fix CI Windows builds (again).
Drop unmaintained "make install" target.
Bugfixes, minor improvements, cleanups.
