Introduced or bumped dependencies:
- brick-2.1.1
- vty-6.1
- vty-crossplatform-0.4.0.0
- vty-windows-0.2.0.1 conditionally on windows (current version of
vty-crossplatform has 0.2.0.0 as a lower bound, need to put a newer version explcitly;
once we get a newer vty-crossplatform, we will be able to drop this conditional)
- vty-unix (indirectly via vty-crossplatform)
