Release checklist

[georgefst]

• Dhall
  • Diamond dependency issue causes huge blowup in size of fully-resolved files. Would be awesome if those were instead small and readable. This could be something we could work around using the existing Haskell API.
  • Deserialising existentials. Even though, without --system-device, we don't care what the type of axis and event data is, we can't accept a Layout Axis Key - it has to be a Layout {} {}. This is really awkward.
• Streamly
  • We probably need Monoid law broken with ExceptT and parallel composition composewell/streamly#1203 fixed, especially when it comes to releasing as a library and exposing ServerConfig.onUpdate. For the executable, it's possible we only use it safely, aside from the error handling issues. EDIT: It's fine, we work around this safely in d9929bd
• documentation
  • should be clear what all CLI flags do
  • Explain how to customize with Dhall #1

When all that's done, we can set up #7, and announce in a few places (r/madeinhaskell? hacker news?).

We can also release on Hackage, with the pre-compiled JS from Elm etc. Though we'll have to have a think about how we handle the platform-specific default.dhall, and the release flag.
