This is the very first open-source VP-Digi release.
## New features
* Viscous-delay and direct-only modes are enabled separately for each digipeater alias: ```digi <0-7> viscous [on/off]``` and ``` digi <0-7> direct [on/off] ```.
**When updating from version <1.2.0 please erase configuration or set new settings carefully.**
* Selectable signal input type: normal (filtered) audio or flat (unfiltered) audio: ```flat [on/off]``` - switches modem settings - before v. 1.2.0 was hardcoded for normal audio
* Erase all settings command: ```eraseall```
## Bug fixes
* none
## Other
* Code was partially rewritten (especially digipeater, modem and AX.25 layer)
## Known bugs
* none
