Hyperglass

Changed

- Removed JS favicon build process in favor of native Python implementation ([favicons](https://github/thatmattlove/favicons))

Fixed

- Queries to hyperglass-agent devices failed due to the error `AttributeError: 'AgentConnection' object has no attribute 'collect'`

Added

- **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/thatmattlove/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

Added

- API route `/api/info`, which displays general system information such as the name of the organization and version of hyperglass.
- API docs configuration parameters for the `/api/info` route.
- [63](https://github.com/thatmattlove/hyperglass/issues/63): Minimum RAM requirements.
- `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/thatmattlove/hyperglass/issues/55): Removed YAML alias & anchors from default examples to avoid confusion.

Fixed

- API docs logo URL now displays correctly.
- [62](https://github.com/thatmattlove/hyperglass/issues/62): Added `epel-release` to CentOS installation instructions.
- [59](https://github.com/thatmattlove/hyperglass/issues/59): Fixed copy output for Juniper devices on non-table output query types.
- [hyperglass-agent 6](https://github.com/hyperglass-agent/issues/6): Fixed hyperglass-agent documentation issues.
- Improve command customization docs.
- [61](https://github.com/thatmattlove/hyperglass/issues/61): Fixed copy output for table data. Output is now a bulleted list of parsed data.

Changed

- Improved config import process & error handling.
- Improved logging initialization so that noisy logs aren't generated on startup unless debugging is enabled.

Fixed

- [54](https://github.com/thatmattlove/hyperglass/issues/54): A Junos parsing error caused routes with no communities to raise an error.
- Pre-validated config files are no longer logged on startup unless debugging is enabled.

Added

- Synchronous API for Redis caching.
- New `redis-py` dependency for synchronous Redis communication.

Changed

- Improved cache type conversion when reading cached data.
- External data via [bgp.tools](https://bgp.tools) is now gathered via their bulk mode API.
- External data via [bgp.tools](https://bgp.tools) is now cached via Redis to reduce external traffic and improve performance.
- RPKI validation via [Cloudflare](https://rpki.cloudflare.com/) is now cached via Redis to reduce external traffic and improve performance.
- Update Python dependencies.

Fixed

- [54](https://github.com/thatmattlove/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).
