This release is the final version of Garage v0.9.0.

Garage v0.9.0 includes the following BREAKING CHANGES:

- LMDB is now the default metadata db engine and Sled is deprecated. Make sure
  you are using the correct value of `db_engine` in your config file before
  updating. **Sled will be removed in Garage v1.0**.

- Capacity values are now in actual byte units. The translation from the old
  layout will assign 1 capacity = 1Gb by default, which might be wrong for your
  cluster. This does not cause any data to be moved around, but users might want
  to re-assign correct capacities to all their nodes to be future-proof.

- Multipart uploads that were started in Garage v0.8 will not be visible in
  Garage v0.9 and will have to be restarted from scratch.

- Updated admin API endpoints, prefixed by `v1/`. For endpoints with
  incompatible syntax, the `v0/` endpoints have been disabled; for others the
  `v0/` URLs are translated automatically to their `v1/` counterpart. **Endpoints
  under `v0/` will be removed in Garage v1.0.**

  - affected admin endpoints: GetClusterStatus, GetClusterHealth, GetClusterLayout, UpdateClusterLayout, ApplyClusterLayout, GetKeyInfo, UpdateKey, CreateKey, ImportKey

- Changes to the `garage key` CLI:

  - `garage key new` is renamed to `garage key create` to be the same as `garage bucket create`
  - `garage key import` will not work without the `--yes` flag and will reject invalid keys (keys that are not generated by Garage)
  - `garage key info` will no longer display the secret key by default (fix #506)

CAUTION:

- `rmp_serde` was updated from 0.15 to 1.1.2, this seems to not break any previously existing data, but more testing is required

Other changes since v0.8.4:

- Optimal layout assignation algorithm (#296)
- Full multipart upload semantics (#204, #553)
- Support for multiple HDDs per server (#218, #625)
- Support for basic lifecycle configurations (#309, #620)
- Uniformized serialization conventions in admin API (#377, #381)
- Added checks to `garage key import` (#278), renamed `garage key new` into `garage key create` (#459)
- Added the `convert_db` subcommand to the main Garage binary (#645)
- Added support for binding API servers to UNIX sockets (#253, #640)
