there are some existing breaking changes behind compile time feature flags. these can be inspected by doing a code search for breaking_changes_1_2

websocket server: ws.subscribe() function will require a string argument
bundler: --sourcemap without an argument is going to default to linked instead of inline
bundler: imports marked external with a second argument will no longer hide that second value (this is done for some backwards compatibility that i want to remove)
