Duplicity 0.8.12 Released

Written for Duplicity by Kenneth Loafman on 2020-03-19

New in v0.8.12 (2020/03/19)
---------------------------
* Fixed bug #1865648 - module 'multiprocessing.dummy' has
  no attribute 'cpu_count'.
  - replaced with module psutil for cpu_count() only
  - appears Arch Linux does not support multiprocessing
* Fixed a couple of file history bugs:
  - #1044715 Provide a file history feature
    + removed neutering done between series
  - #1526557 --file-changed does not work
    + fixed str/bytes issue finding filename
* Fixed bug #1755955 - best order is unclear,
  of exclude-if-present and exclude-device-files
  - Removed warning and will now allow these two to
    be in any order. If encountered outside of the
    first two slots, duplicity will silently move
    them to be in the first two slots. Within those
    two slots the order does not matter.
* Fixed bug #1769267 - [enhancement] please consider
  using rclone as backend.
* Cleaned up some setup issues where the man pages
  and snapcraft.yaml were not getting versioned.
* Fixed bug #1867435 - TypeError: must be str,
  not bytes using PCA backend
* Fixed bug #1867444 - UnicodeDecodeError: 'ascii'
  codec can't decode byte 0x85 in position 0:
  ordinal not in range(128) using PCA backend
* Fixed bug #1867468 - UnboundLocalError (local
  variable 'ch_err' referenced before assignment)
  in ssh_paramiko_backend.py
* Fixed bug #1867529 - UnicodeDecodeError: 'ascii'
  codec can't decode byte 0x85 in position 0:
  ordinal not in range(128) with PCA
* Fixed bug #1867742 - TypeError: fsdecode()
  takes 1 positional argument but 2 were given
  with PCA backend
* Merged in translation updates
