* Multiple minor fixes | [ipfs/ipfs-cluster#236](https://github.com/ipfs/ipfs-cluster/issues/236)
* Avoid shutting down consensus in the middle of a commit
* Return an ID containing current peers in PeerAdd
* Do not shut down libp2p host in the middle of peer removal
* Send cluster addresses to the new peer before adding it
* Wait for configuration save on init
* Fix error message when not enough allocations exist for a pin
This releases introduces some changes affecting the configuration file and some breaking changes affecting `go` and the REST APIs:
* The `consensus.raft` section of the configuration has new options but should be backwards compatible.
* The `Consensus` component interface has changed, `LogAddPeer` and `LogRmPeer` have been replaced by `AddPeer` and `RmPeer`. It additionally provides `Clean` and `Peers` methods. The `consensus/raft` implementation has been updated accordingly.
* The `api.ID` (used in REST API among others) object key `ClusterPeers` key is now a list of peer IDs, and not a list of multiaddresses as before. The object includes a new key `ClusterPeersAddresses` which includes the multiaddresses.
* Note that `--bootstrap` and `--leave` flags when calling `ipfs-cluster-service` will be stored permanently in the configuration (see [ipfs/ipfs-cluster#235](https://github.com/ipfs/ipfs-cluster/issues/235)).
* Peers and bootstrap entries in the configuration are ignored | [ipfs/ipfs-cluster#203](https://github.com/ipfs/ipfs-cluster/issues/203) | [ipfs/ipfs-cluster#204](https://github.com/ipfs/ipfs-cluster/issues/204)
* Informers do not work on 32-bit architectures | [ipfs/ipfs-cluster#202](https://github.com/ipfs/ipfs-cluster/issues/202) | [ipfs/ipfs-cluster#205](https://github.com/ipfs/ipfs-cluster/issues/205)
* Replication factor entry in the configuration is ignored | [ipfs/ipfs-cluster#208](https://github.com/ipfs/ipfs-cluster/issues/208) | [ipfs/ipfs-cluster#209](https://github.com/ipfs/ipfs-cluster/issues/209)
The fix for 32-bit architectures has required a change in the `IPFSConnector` interface (`FreeSpace()` and `Reposize()` return `uint64` now). The current implementation by the `ipfshttp` module has changed accordingly.
* Basic authentication support added to API component | [ipfs/ipfs-cluster#121](https://github.com/ipfs/ipfs-cluster/issues/121) | [ipfs/ipfs-cluster#147](https://github.com/ipfs/ipfs-cluster/issues/147) | [ipfs/ipfs-cluster#179](https://github.com/ipfs/ipfs-cluster/issues/179)
* Copy peers to bootstrap when leaving a cluster | [ipfs/ipfs-cluster#170](https://github.com/ipfs/ipfs-cluster/issues/170) | [ipfs/ipfs-cluster#112](https://github.com/ipfs/ipfs-cluster/issues/112)
* New configuration format | [ipfs/ipfs-cluster#162](https://github.com/ipfs/ipfs-cluster/issues/162) | [ipfs/ipfs-cluster#177](https://github.com/ipfs/ipfs-cluster/issues/177)
* Freespace disk metric implementation. It's now the default. | [ipfs/ipfs-cluster#142](https://github.com/ipfs/ipfs-cluster/issues/142) | [ipfs/ipfs-cluster#99](https://github.com/ipfs/ipfs-cluster/issues/99)
* Fixes:
* IPFS Connector should use only POST | [ipfs/ipfs-cluster#176](https://github.com/ipfs/ipfs-cluster/issues/176) | [ipfs/ipfs-cluster#161](https://github.com/ipfs/ipfs-cluster/issues/161)
*`ipfs-cluster-ctl` exit status with error responses | [ipfs/ipfs-cluster#174](https://github.com/ipfs/ipfs-cluster/issues/174)
* Sharness tests and update testing container | [ipfs/ipfs-cluster#171](https://github.com/ipfs/ipfs-cluster/issues/171)
*`ipfs-cluster-service`: Do not run service with unknown subcommands | [ipfs/ipfs-cluster#186](https://github.com/ipfs/ipfs-cluster/issues/186)
This release introduces some breaking changes affecting configuration files and `go` integrations:
* Config: The old configuration format is no longer valid and cluster will fail to start from it. Configuration file needs to be re-initialized with `ipfs-cluster-service init`.
* Go: The `restapi` component has been renamed to `rest` and some of its public methods have been renamed.
* Go: Initializers (`New<Component>(...)`) for most components have changed to accept a `Config` object. Some initializers have been removed.
