Daml Compiler

• BREAKING CHANGE Handwritten instances of Template and Choice typeclasses are no longer supported. All template constructs must be defined using declarations inside template syntax.

Daml Docs

• The damlc docs command now produces docs to a folder by default. Use the new --combine flag to output a single file instead.
• The damlc docs flag --prefix has been replaced with a --template flag which allows for a more flexible template.
• The damlc docs flag --json has been dropped in favor of --format=json.
