If you use [hyperglass-agent](https://github.com/checktheroads/hyperglass-agent), you must upgrade your version of hyperglass-agent to 0.1.6 or later. If using hyperglass-agent with SSL, this release will require you to re-generate & re-send your SSL certificates to hyperglass:
```console
$ hyperglass-agent certificate
$ hyperglass-agent send-certificate
```
### Changed
- Verify a device's address is either an IPv4 or IPv6 address, or a resolvable hostname.
- Devices using hyperglass-agent (FRR, BIRD) no longer need to use a DNS-resolvable hostname in the `address:` field, as long as the certificate has been generated by hyperglass-agent, and the proper IP addresses were selected during the prompts to generate the certificate. *If using your own certificate and you want to connect to hyperglass-agent via an IP address instead of a hostname, you need to ensure the IP address of hyperglass-agent is listed as a Subject Alternative Name in the certificate extensions.*
- Refactored device, query, proxy models to no longer scrub unsupported characters from the device name for the purposes of Python class attribute accessing.
- [#56](https://github.com/checktheroads/hyperglass/issues/56): Fix a silent Redis connection error if the Redis server was anything other than `localhost`, preventing hyperglass from starting.
- **BREAKING CHANGE**: [Scrapli](https://github.com/carlmontanari/scrapli) is now used for SSH connectivity to Cisco IOS, Cisco IOS-XE, Cisco IOS-XR, Cisco NX-OS Juniper Junos, and Arista EOS, which should improve the speed at which output is gathered from devices. _As of this release, Cisco IOS/IOS-XE and Juniper Junos have been directly tested and worked without issue. However, if you discover any anomalies with any of these operating systems, please [open an issue](https://github.com/checktheroads/hyperglass/issues)._
### Changed
- Refactor of SSH & HTTPS command execution to enable pluggable underlying driver capabilities.
- Remove `aiofile` dependency by removing unnecessary asyncio file operations in the UI build process.
- Added `scrapli[asyncssh]` dependency for Scrapli driver support.
### Fixed
- UI: Error messages couldn't be copied with the copy button
-`hyperglass system-info` CLI command to gather system CPU, Memory, Disk, Python Version, hyperglass Version, & OS info. _Note: this information is only gathered if you run the command, and even then, is printed to the console and not otherwise shared or exported_.
### Changed
- Updated docs dependencies.
- Improved YAML alias & anchor docs.
- [#55](https://github.com/checktheroads/hyperglass/issues/55): Removed YAML alias & anchors from default examples to avoid confusion.
- [#54](https://github.com/checktheroads/hyperglass/issues/54): A Junos structured/table output parsing error caused routes with multiple next-hops to raise an error.
- RPKI validation no longer occurs twice (once on serialization of the output, once on validation of the API response).
- New NOS: **VyOS**. [See docs for important caveats](https://hyperglass.io/docs/commands).
### Fixed
- UI: If the logo `width` parameter was set to ~ 50% and the `title_mode` was set to `logo_subtitle`, the subtitle would appear next to the logo instead of underneath.
- When copying the opengraph image, the copied image was not deleted.
- Default traceroute help link now *actually* points to the new docs site.
