 (In terms of the parser unit test suite, this change eliminated around 20 situations where LightScript was parsing vanilla JavaScript incorrectly, as well as four parsing situations labeled as `unfortunate` in the test suite itself.)
 
-## `whiteblock` compiler option added.
-
-### Change
-
-When this option is enabled, only whitespace-delimited syntax can be used for introducing blocks of code. `{ }` are reserved for object literals and some other constructs like `import`/`export`.
-
-For example,
-```js
-f(x) ->
-  y
-// compiles to
-function(x) { return y; }
-// both with and without `whiteblock`
-
-// However,
-f(x) -> {
-  y
-}
-// compiles to
-function(x) { return y; }
-// without `whiteblock`, but with `whiteblock`, the `{`s are interpreted
-// as delimiting an object, so instead you get
-function(x) {
-  return { y }
-}
-```
-
-In the simplest possible terms, `whiteblock` makes the compiler behave as if you are always writing idiomatic whitespaced LightScript code, and so `{}`s will never be used to set off code blocks.
-
-### Rationale
-
-The context-sensitive brace parser is implemented using speculative branching, which can essentially double the amount of work the parser has to do in a lot of situations. This flag will greatly speed up the LightScript parser for those who use whitespace-sensitive syntax, as it is no longer necessary for the parser to speculate when encountering `{ }`.

 ## `pipeCall` option eliminated
