# [9.0.0](https://github.com/yargs/yargs/compare/v8.0.2...v9.0.0) (2017-09-03)

### Bug Fixes

* 'undefined' default value for choices resulted in validation failing ([782b896](https://github.com/yargs/yargs/commit/782b896))
* address bug with handling of arrays of implications ([c240661](https://github.com/yargs/yargs/commit/c240661))
* defaulting keys to 'undefined' interfered with conflicting key logic ([a8e0cff](https://github.com/yargs/yargs/commit/a8e0cff))
* don't bother calling JSON.stringify() on string default values ([#891](https://github.com/yargs/yargs/issues/891)) ([628be21](https://github.com/yargs/yargs/commit/628be21))
* exclude positional arguments from completion output ([#927](https://github.com/yargs/yargs/issues/927)) ([71c7ec7](https://github.com/yargs/yargs/commit/71c7ec7))
* strict mode should not fail for hidden options ([#949](https://github.com/yargs/yargs/issues/949)) ([0e0c58d](https://github.com/yargs/yargs/commit/0e0c58d))

### Features

* allow implies and conflicts to accept array values ([#922](https://github.com/yargs/yargs/issues/922)) ([abdc7da](https://github.com/yargs/yargs/commit/abdc7da))
* allow parse with no arguments as alias for yargs.argv ([#944](https://github.com/yargs/yargs/issues/944)) ([a9f03e7](https://github.com/yargs/yargs/commit/a9f03e7))
* enable .help() and .version() by default ([#912](https://github.com/yargs/yargs/issues/912)) ([1ef44e0](https://github.com/yargs/yargs/commit/1ef44e0))

### BREAKING CHANGES

* version() and help() are now enabled by default, and show up in help output; the implicit help command can no longer be enabled/disabled independently from the help command itself (which can now be disabled).
* parse() now behaves as an alias for .argv, unless a parseCallback is provided.

### BREAKING CHANGES

* extends functionality now always loads the JSON provided, rather than reading from a specific key
* Node 4+ is now required; this will allow us to start updating our dependencies.
* the first argument to strict() is now used to enable/disable its functionality, rather than controlling whether or not it is global.

### BREAKING CHANGES

* `extends` key in config file is now used for extending other config files
* environment variables now take precedence over config files.
* context now takes precedence over argv and defaults
* the arguments passed to functions are now validated, there's a good chance this will throw exceptions for a few folks who are using the API in an unexpected way.
* by default options, and many of yargs' parsing helpers will now default to being applied globally; such that they are no-longer reset before being passed into commands.
* yargs will no longer aggressively suppress errors, allowing errors that are not generated internally to bubble.
