=== Optimizations/improvements ===
* [[Invisible files]] restore is de-serialized
* VMAs restore performance is improved significantly
** Mappings of the same file re-use the descriptor, not re-open it every time
** Not-COW-ed mappings are restored in-place and are not mremmap()ed
** Empty RO mappings are mmap()ed as such and thus not re-mprotect()ed at the end
* More verbosity in case TCP locking fails ({{Bug|292}})
* More verbosity in case VDSO magic mismatch
* Restore or legacy epoll target descriptors and fsnotify marks is unified with common case

* Restoring fanotify marks from old images (<1.3) dropped the mark
* Binfmt_misc mount could be mounted into wrong place
* Compilation failed with gcc 6.3.0 ({{Bug|315}})
* Waiting helpers could race with sigchild handler and would result in restore failure
* Missing VVAR page in 32bit tasks wasn't skipped and resulted in restore failure
* After restore consumption of files is increased (was fixed as side effect of mmap optimization)
=== Deprecation/Removal ===
* Deprecated separate images for fsnotify marks
