v2.2.0

The channel colours are the channel's own. Turning the water lines down, and turning them any
colour you like, both work now.

• Every state of a stretch has its own colour. Dug-but-unfloored and iced used to borrow the
  node colours from the Display tab, so the one button that said it coloured the channel moved the
  cyan and left the yellow and the green exactly as they were. Five colours, each labelled with the
  state it paints: Not dug, Dug, no ice, Iced, Bad run, Drain.
• An opacity setting for the water lines. It existed in the config file and was never on screen.
  The outline of a stretch follows it too instead of staying pinned at full strength, which is what
  made turning it down look like it did nothing.
• A Look tab on the Water page, between Setup and Cost, for how the channel is drawn: show it or
  not, opacity, the five colours, and the sources-and-plates proposal. Setup keeps what the network
  is made of. The colours were squeezed into Setup's right hand column, which is why there was room
  for one of them and not three.

Minecraft 26.1.2, and what 2.1.0 was supposed to be. 2.1.0 was tagged and never published: its
release failed on the 26.x builds and nothing was uploaded, so this is the first release since
2.0.0 and it carries both.

• A jar for 26.1.2, which is the first Minecraft that ships unobfuscated. Everything about
  building for it is different: there are no mappings to remap against any more, the build script
  uses the plugin that does not remap, and the game wants Java 25. Treat it as a beta. It
  compiles clean against the real 26.1.2 API, and unlike the 1.21 jars nobody has had it in a world
  yet.
• 26.2 is not here yet. It replaced the path a mod's own geometry takes to the screen, not just
  the names on it, and that is a rewrite rather than a port. It is next.
• Every jar now declares the one version it was compiled for again. Since 2.1.0 they all claimed
  >=1.21 <26.3, which let Fabric load a 1.21 jar on a version it was never built against.
