0.21.12

Added

• Somewhat simplified the handling of "uniqueness types" (which is a
  term we are moving away from). You should never see * in
  non-function types, and they are better thought of as effect
  indicators.

• futhark literate: prints tracing output (and other logging
  messages that may occur) when run with -v (#1678).

• Entry points can now be any valid Futhark identifier.

Fixed

• futhark test -C was broken.

• futhark_context_free() for the GPU backends neglected to free some
  memory used for internal bookkeeping, which could lead to memory
  leaks for processes that repeatedly create and destroy contexts
  (#1676).

• FutharkScript now allows ' in names.

• futhark lsp now handles warnings in programs that also have errors.
