* Breaking changes note about bound class methods
* Changelog for 2.0.0-beta2, including renaming “Change Log” to “Changelog” (the preferred spelling per Wikipedia)
* Update version to 2.0.0-beta2
* 2.0.0-beta2 generated output
* Docs: named functions and function declarations
* No more prototypal `extends`; update docs and example
* More comprehensive documentation of the existential operator; closes#1631
* Better document operators, including `from`
* No fat arrow class methods anymore
* Destructuring shouldn’t say that default values are applied in case of undefined or null
* Spinoff generator and async functions into their own sections; reorder things so that the sections on functions come just before classes, and destructuring goes next to the operators (which discuss assignment)
* Rewrite “CoffeeScript 2” section, making it less practical and more explanatory; move practical info into “Usage”
* Update “Variable Scoping and Lexical Safety” section to remove incorrect reference to Ruby (fixes#2360), add missing details about the safety wrapper, add note about `let`/`const`.
* Updated browser compiler
* Updated docs
* Rewrite Literate CoffeeScript breaking changes
* Split apart the “Breaking Changes” and “Unsupported Features” sections into separate sidebar items and files
* Add example of `not in`, closes#3281
* Fix words in bold that should be in backticks
* Consolidate some breaking changes sections
* Add Node API documentation; closes#3551
* Move the chaining documentation out of the changelog into its own section
* Swap Google Closure Compiler for Babili
* Browser compiler, minified by Babili
* Use Babel to transform, not just to minify; add process.env.TRANSFORM to disable transforming if we only want to minify. Unfortunately several browser tests fail when transformed . . .
* Move `super()` calls so that the Babel-transformed browser compiler passes all the browser tests (in Node, at least)
* Updated browser build
* Update browser tests
* Fix browser build to incorporate Markdown-It, not Marked
* Update Google Closure Compiler; recompile browser build but with MINIFY=false, because Closure Compiler throws an error on our current code; see https://github.com/google/closure-compiler-js/issues/59
* Bump version to 2.0.0-beta1; do release build, with updated docs and annotated source
