The software is technically called ended in 2017 with version number 1.22. +# Version 0.7.X, released 2022-07-24 + +## Breaking changes + +Breaking changes are ones that mean existing backups can't be +restored, or new backups can't be created. + +* The list of backups is stored in a special "root chunk". This means + backups are explicitly ordered. This also paves way for a future + feature to backups: only the root chunk will need to be updated. + Without a root chunk, the backups formed a linked list, and deleting + from the middle of the list would updating the whole list. + +* The server chunk metadata field `sha256` is now called `label`. + Labels include a type prefix, to allow for other chunk checksum + types in the future. + +* The server API is now explicitly versioned, to allow future changes + to cause less breakage. + +## New features + +* Users can now choose the backup schema version for new backups. A + repository can have backups with different schemas, and any existing + backup can be restored. The schema version only applies to new + backups. + +* New command `obnam inspect` shows metadata about a backup. Currently + only the schema version is shown. + +* New command `obnam list-backup-versions` shows all the backup schema + versions that this version of Obnam supports. + +* Obnam now logs some basic performance measurement for each run: how + many live files were found in total, backed up, chunks uploaded, + existing chunks reused, and how long various parts of the process + took. + +## Other changes + +* The `obnam show-generation` command now outputs data in the JSON + format. The output now includes data about the generation's SQLite + database size. + +## Thank you + +Several people have helped with this release, with changes or +feedback. + +* Alexander Batischev +* Lars Wirzenius + # Version 0.7.1, released 2022-03-08 ## Bug fixes |
