   - borg import/export-tar --tar-format=GNU/PAX/BORG, support ctime/atime PAX headers.
     GNU and PAX are standard formats, while BORG is a very low-level custom format only
     for borg usage.
+  - borg create: add the "slashdot hack" to strip path prefixes in created archives
+  - borg version: show local/remote borg version
 
 - removed commands / options:
 
   - removed -P (aka --prefix) option, use -a (aka --match-archives) instead, e.g.: -a 'PREFIX*'
   - borg upgrade (was only relevant for attic / old borg)
   - removed deprecated cli options
+  - remove recreate --recompress option, the repo-wide "rcompress" is more efficient.
