== Compatibility notes ==
* this version requires running vzkernel >= 2.6.32-042stab061.1
* snapshots created by old ploop tools are not compatible with this version
* there were a few incompatible library API changes, see below

== Changes ==
Since {{dlink|ploop|1.4}}
'''New functionality:'''
* switch from old /dev/ploop/ symlink-based to new in-kernel cookie registration
* snapshots: switch to schema with constant top delta uuid
* use /proc/vz/ploop_minor based interface to get free minor
* if ploop device is in maintenance state, try to complete it before doing snapshot/resize/merge/mount/umount/copy operation
* ploop mount: use in-kernel I/O module autodetection
* ploop balloon discard: new iterative compacting support
* ploop balloon discard: implement --stat
* ploop balloon discard: implement --automount
* ploop balloon discard: cancellation support
* ploop balloon: allow DiskDescriptor.xml argument
* ploop umount: implement -c component_name
* ploop list: implement
* /sbin/mount.ploop: do load ploop modules
'''Bug fixes:'''
* do not crash on empty DiskDescriptor.xml (libxml2 workaround)
* ploop convert: fix converting from expanded to raw
* ploop copy: fixed check for opened fd
* ploop copy: do not leak opened fds
* ploop create: fix gpt partition creation to be 4096 aligned
* tools: few exit code fixes
* multiple usage, log and error message fixes
'''Library API changes:'''
* implement dynamic library loading via ploop_resolve_functions()
* introduce optimized ploop_get_info_by_descr(), remove ploop_get_info()
* replace ploop_{alloc,read}_diskdescriptor() with ploop_read_disk_descr()
* remove ploop_getdevice()
'''Improvements:'''
* ploop mount: check that mount point is a directory
* ploop umount: reduce retry count from 60 to 6
* ploop create: for prealloc image, use ftruncate if fallocate not supported
* ploop create, resize: add check for correct block device size
* scripts: de-bash-ify
* assorted code refactoring, cleanups and nitpicks
