### Overview
|
|
|
|
### 🔦 Highlights
|
|
|
|
#### Saving previously seen nodes for later bootstrapping
|
|
|
|
Kubo now stores a subset of connected peers as backup bootstrap nodes ([kubo#8856](https://github.com/ipfs/kubo/pull/8856)).
|
|
These nodes are used in addition to the explicitly defined bootstrappers in the
|
|
[`Bootstrap`](https://github.com/ipfs/kubo/blob/master/docs/config.md#bootstrap) configuration.
|
|
|
|
This enhancement improves the resiliency of the system, as it eliminates the
|
|
necessity of relying solely on the default bootstrappers operated by Protocol
|
|
Labs for joining the public IPFS swarm. Previously, this level of robustness
|
|
was only available in LAN contexts with [mDNS peer discovery](https://github.com/ipfs/kubo/blob/master/docs/config.md#discoverymdns)
|
|
enabled.
|
|
|
|
With this update, the same level of robustness is applied to peers that lack
|
|
mDNS peers and solely rely on the public DHT.
|
|
|
|
#### `Gateway.DeserializedResponses` config flag
|
|
|
|
This release introduces the
|
|
[`Gateway.DeserializedResponses`](https://github.com/ipfs/kubo/blob/master/docs/config.md#gatewaydeserializedresponses)
|
|
configuration flag.
|
|
|
|
With this flag, one can explicitly configure whether the gateway responds to
|
|
deserialized requests or not. By default, this flag is enabled.
|
|
|
|
Disabling deserialized responses allows the
|
|
gateway to operate
|
|
as a [Trustless Gateway](https://specs.ipfs.tech/http-gateways/trustless-gateway/)
|
|
limited to three [verifiable](https://docs.ipfs.tech/reference/http/gateway/#trustless-verifiable-retrieval)
|
|
response types:
|
|
[application/vnd.ipld.raw](https://www.iana.org/assignments/media-types/application/vnd.ipld.raw),
|
|
[application/vnd.ipld.car](https://www.iana.org/assignments/media-types/application/vnd.ipld.car),
|
|
and [application/vnd.ipfs.ipns-record](https://www.iana.org/assignments/media-types/application/vnd.ipfs.ipns-record).
|
|
|
|
With deserialized responses disabled, the Kubo gateway can serve as a block
|
|
backend for other software (like
|
|
[bifrost-gateway](https://github.com/ipfs/bifrost-gateway#readme),
|
|
[IPFS in Chromium](https://github.com/little-bear-labs/ipfs-chromium/blob/main/README.md)
|
|
etc) without the usual risks associated with hosting deserialized data behind
|
|
third-party CIDs.
|
|
|
|
#### `client/rpc` migration of `go-ipfs-http-client`
|
|
|
|
The [`go-ipfs-http-client`](https://github.com/ipfs/go-ipfs-http-client) RPC has
|
|
been migrated into [`client/rpc`](./client/rpc).
|
|
|
|
With this change the two will be kept in sync, in some previous releases we
|
|
updated the CoreAPI with new Kubo features but forgot to port thoses to the
|
|
http-client, making it impossible to use them together with the same coreapi
|
|
version.
|
|
|
|
**TODO(@Jorropo)**: add link to `boxo-migrate` once support for rewriting this import path has been added
