@ -84,6 +84,15 @@ This file describes changes between the metabase versions.
- Key: split ID
- Value: list of object IDs
# History
## Version 2
- Container ID is encoded as 32-byte slice
- Object ID is encoded as 32-byte slice
- Object ID is encoded as 64-byte slice, container ID + object ID
- Bucket naming scheme is changed:
- container ID + suffix -> 1-byte prefix + container ID
## Version 1
