- [#87](https://github.com/checktheroads/hyperglass/issues/87): [TNSR] Support. To add a TNSR device, use the `tnsr` [NOS key](https://hyperglass.io/docs/adding-devices#all-device-parameters).
### Fixed
- Fix an issue causing hyperglass custom exceptions to not be properly raised, which caused more generic error messages in the UI/API.
When hyperglass starts up, it will check to see if `~/hyperglass` or `/etc/hyperglass/` exists. Previously, it would silently choose the first one found, even if both exist. Now, if both exist, an exception is raised with instruction to delete one of them. If your system has both directories, hyperglass may not start up normally after you upgrade.
### Fixed
- Fix a DNS resolution issue which caused Debian systems to be unable to resolve the hostnames of any devices. This was due to differences in how the Python socket module works on Debian vs other distros (even Ubuntu).
### Added
- [#81](https://github.com/checktheroads/hyperglass/issues/81): Add support for SSH key authentication. See [the docs](https://hyperglass.io/docs/adding-devices#credential) for more details.
- [#90](https://github.com/checktheroads/hyperglass/issues/90): Fix a typing error that caused ping & traceroute queries to fail for certain devices.
### Added
- [#82](https://github.com/checktheroads/hyperglass/issues/82): Add support for Redis password authentication. Authentication can be configured in the following manner:
```yaml
# hyperglass.yaml
cache:
password: examplepassword
```
This would correspond with the following stanza in the Redis configuration file:
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.
