  determine the latest archive.
• #1317: Add an "archive_hostname" option and a corresponding "--archive-hostname" flag for
  overriding the hostname used for the "{hostname}" placeholder in the "archive_name_format"
  option. Also add an "archive_username" option and corresponding "--archive-username" flag to
  override the "{user}" placeholder. Both options/flags are Borg 1.4.5+ only.
• #1319: Fix the ZFS hook's overzealous unmounting of snapshot paths when a source dataset is at

• #1327: Fix an error from the "diff" action when exclude options are configured.

  logs and avoid inadvertently suppressing other error logs.

  segment compaction.
• #1334: Add the "CAP_FOWNER" capability to "CapabilityBoundingSet" in the sample systemd service,

  present.
