mdbx: LCK-format version 3.
...
The LCK file is re-created at every opportunity when the process that
opens the database is the only one that works with it. Thus the change
of the format of the file LCK creates only minimal compatibility
problems.
Applications using different versions of _libmdbx_ will be able to work
with one database alternately, but not at the same time. This appears to
be an acceptable inconvenience in exchange for new features.
