### Changed
- Minimum Supported Rust Version (MSRV) bumped to 1.63
- Minimum Supported Rust Version (MSRV) bumped to 1.67
- ASB can now register with multiple rendezvous nodes. The `rendezvous_point` option in `config.toml` can be a string with comma separated addresses, or a toml array of address strings.

The ASB daemon supports the libp2p [rendezvous-protocol](https://github.com/libp2p/specs/tree/master/rendezvous).
Usage of the rendezvous functionality is entirely optional.
You can configure a rendezvous point in the `[network]` section of your config file.
You can configure one or more rendezvous point in the `[network]` section of your config file.
For the registration to be successful, you also need to configure the externally reachable addresses within the `[network]` section.
For example:
```toml
[network]
rendezvous_point = "/dns4/discover.unstoppableswap.net/tcp/8888/p2p/12D3KooWA6cnqJpVnreBVnoro8midDL9Lpzmg8oJPoAGi7YYaamE"
rendezvous_point = [
"/dns4/discover.unstoppableswap.net/tcp/8888/p2p/12D3KooWA6cnqJpVnreBVnoro8midDL9Lpzmg8oJPoAGi7YYaamE",
"/dns4/eratosthen.es/tcp/7798/p2p/12D3KooWAh7EXXa2ZyegzLGdjvj1W4G3EXrTGrf6trraoT1MEobs",
]
external_addresses = ["/dns4/example.com/tcp/9939"]
