NOTE: Add new changes BELOW THIS COMMENT.

### Added
- The ability to edit rewrite rules via `PUT /control/rewrite/update` HTTP API
([#1577]).
[#1577]: https://github.com/AdguardTeam/AdGuardHome/issues/1577
<!--
NOTE: Add new changes ABOVE THIS COMMENT.

## [v0.107.30] - 2023-06-07
See also the [v0.107.30 GitHub milestone][ms-v0.107.30].
### Security
- Go version has been updated to prevent the possibility of exploiting the
CVE-2023-29402, CVE-2023-29403, and CVE-2023-29404 Go vulnerabilities fixed in
[Go 1.19.10][go-1.19.10].
### Fixed
- Unquoted IPv6 bind hosts with trailing colons erroneously considered
unspecified addresses are now properly validated ([#5752]).
**NOTE:** the Docker healthcheck script now also doesn't interpret the `""`
value as unspecified address.
- Incorrect `Content-Type` header value in `POST /control/version.json` and `GET
/control/dhcp/interfaces` HTTP APIs ([#5716]).
- Provided bootstrap servers are now used to resolve the hostnames of plain
UDP/TCP upstream servers.
