# v0.19.0
* Enhancements
  * Added elixir_script mix compiler

* Breaking
  * `Html`, `View`, and `VDom` modules have been removed

# v0.18.0
* Enhancements
  * Better support for macros. Macros should be defined in .ex or .exs files. ElixirScript code should be in .exjs files

* Breaking
  * The above functionality will cause either compiler errors or no output. Please change extensions of ElixirScript code to .exjs

* Deprecations
  * `Html`, `View`, and `VDom` modules will be removed in the next version as they can now be replicated using macros

# v0.17.0
* Enhancements
  * Incremental Compilation:
    ElixirScript will now only build files and modules that have changed since the last build
  * Added `output` as an option for compiler functions. This controls whether output is returned as a list of tuples, send to stdout, or saved to a file path
  * Added `:full_build` as an option for compiler functions and `--full-build` option to CLI. These force the compiler to perform a full build
  * Added `--version` option to CLI. Outputs current version of elixirscript
  * Added `--std-lib` option to CLI. Takes a path and adds the stdlib to that path

* Breaking
  * Removed `--core` option from CLI and `:core` compiler option.
  * Renamed `copy_core_to_destination` to `copy_stdlib_to_destination`

# v0.16.0
* Enhancements
  * Bitstring pattern matching
  * Bitstrings in for comprehensions
  * Functions with catch, after, else clauses
  * `with` special form
  * Pin operator in map keys and function clauses
  * Added `Kernel.object/1` function to make it more natural to create a JavaScript object with string keys
    Elixirscript, by default turns the following, `%{a: "b"}` into `{[Symbol.for("a")]: "b"}` in JavaScript. In order to get string keys,
    one would have to do `%{"a" => "b"}` which turns into `{a: "b"}` in JavaScript. With `Kernel.object`, you can create string keyed maps
    conveniently, `object(a: "b")` which turns into `{a: "b"}`.

    **NOTE**: when updating the created by, you still have to use the string form `%{ my_map | "a" => "c" }`

* Bugfixes
  * Optional parameters should now work as expected

* Breaking
  * `JS.update(object, property, value)` has been removed and replaced with `JS.update(object, map)`
    This allows you to update multiple values on a javascript object at once.

# v0.15.0
* Enhancements
  * `alias`, `require`, and `import` now work inside lexical scopes
  * `__ENV__` and `__CALLER__` are now supported
  * Some of the standard library originally written in JavaScript has been rewritten
    in Elixir.
  * Added `JS.import/1`, `JS.typeof/1`,`JS.instanceof/1`, and `JS.global/1`
  * Added support for multi alias/require/imports statements
  * Generated JavaScript export statements are now default exports
  * When output is sent to standard out, there are now markers to specify where
    each module begins as well as what the file name would be.
    For the end of a file, `//:ENDFILE` is used. For the file name, `//<file>:ENDFILENAME`
    is used where `<file>` is the name of the file

* Breaking
  * `compile`, `compile_path`, and `compile_quoted` opts parameter now expects a map
  * The `stdlib` compiler option is now `core`. The `stdlib_path` compiler options is now
  `core_path`

# v0.14.1
* Enhancements
  * Removed .DS_Store and LICENSE from output

# v0.14.0
* Breaking
  * Renamed `ex2js` to `elixirscript`. This effects the escript as well as the
  mix task
* Enhancements
  * Structs are now translated into classes
  * Structs and Tuples now match on their types
  * Can now match on JavaScript classes. Works just like matching on structs:
  ```elixir
    def my_func(%HTMLElement{id: "myId"})
  ```
  * Can now implement protocols using JavaScript types
  ```elixir
    defimpl MyProtocol, for: HTMLElement
  ```
  * Added virtual-dom JavaScript library
  * Added ElixirScript.Html module for defining a virtual-dom tree
  * Added ElixirScript.VDom module for manipulating the virtual-dom tree created
  using the ElixirScript.Html module
  * Added ElixirScript.View module for handling view state and rendering virtual-dom
  * Added `stdlib_path` compiler option to specify the es6 path to the standard library.
  If used, elixir.js will not be exported with the compiled modules
  * Moved non-elixir JavaScript code into `core` es6 module. This will hopefully
  make it so ElixirScript Standard Library modules can be defined in Elixir soon.
