 - command line syntax was changed, scripts and wrappers will need changes:

   - the scp-style REPO syntax was removed, please use ssh://..., #6697

   - use -r or --repo or BORG_REPO env var to give the repository
   - use --other-repo or BORG_OTHER_REPO to give another repo (e.g. borg transfer)
   - use positional argument for archive name or `-a ARCH_GLOB`
-
 - remove support for scp-style repo specification, use ssh://...
 - simplify stats output: repo ops -> repo stats, archive ops -> archive stats
-
 - repository index: add payload size (==csize) and flags to NSIndex entries
 - repository index: set/query flags, iteration over flagged items (NSIndex)
 - repository: sync write file in get_fd
-
 - stats: deduplicated size now, was deduplicated compressed size in borg 1.x
 - remove csize support at most places in the code (chunks index, stats, get_size,
   Item.chunks)
-
 - replace problematic/ugly hardlink_master approach of borg 1.x by:
 
   - symmetric hlid (all hardlinks pointing to same inode have same hlid)
   - all archived hardlinked regular files have a chunks list
-
 - borg init --other-repo=OTHER_REPO: reuse key material from OTHER_REPO, #6554.
   This is useful if you want to use borg transfer to transfer archives from an
   existing borg 1.1/1.2 repo. If the chunker secret and the id key and algorithm
   stay the same, the deduplication will also work between past and future backups.

 - borg transfer:
 
   - efficiently copy archives from a borg 1.1/1.2 repo to a new repo.
