- Various general (but very important) speed improvements [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96) [\[#102\]](https://github.com/aiidateam/disk-objectstore/pull/102)
- Add callbacks to a number of functions (e.g. export, add_objects_to_pack, ... to allow showing progress bars or similar indicators [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96)
- Implement repacking (at least when not changing hashing or compression) [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96)
- Remove `export` function, implement `import_objects` function instead, to be called on the other side (it's more efficient) [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96)
- Add support for VACUUMing operations on the SQLite database (very important for efficiency) [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96)
- Add support for multiple hashing algorithms [\[96\]](https://github.com/aiidateam/disk-objectstore/pull/96)
- Add concept of (unique) `container_id` [\[97\]](https://github.com/aiidateam/disk-objectstore/pull/97)
- Generalize the compression algorithm implementation, and multiple algorithms are supported now [\[99\]](https://github.com/aiidateam/disk-objectstore/pull/99)
