- Update to 0.13:
* Add a new dedupe option: [no]rescan_files. It will increase
performance in some use cases.
* New behaviors from v0.12 has been consolidated. Extent-based
lookup is always enabled, as is fiemap. The v2
hashfile is no longer supported.
* Hashfile are now updated after deduplication, to reflect the
new physical offsets. This avoid (re)deduplicating extents
in some cases.
* Partial mode has been enhanced to support batching. The
overall performance of this mode (which was previously known
as "block-based mode") has been improved.
* All files are now open in readonly mode.
* Hashfile version has been increased to reflect the new
database behaviors. Previous hashfiles are not compatible.
* Always compute a hash for the entire file. This let us
deduplicate same files easily, regardless of their
extents mappings.
* Deduplicating only parts of a file can be disabled using
the [no]only_whole_files dedupe option.
* Hashfiles with unsupported features or hash algorithm are
now recreated transparently. Migration of the old content
is not implemented.
* Relative exclude patterns are no longer silently ingested.
Such patterns are now rebuilt on top of the current
working directory.
* Batching is now set to 1024 by default.
