### Fixed
- omit masked help flags from the displayed help ([#645], [#1247])
- remove old short help flag when change help flags using `helpOption` ([#1248])
### Changed

## [5.0.0] (2020-03-14)
### Added
* support for nested commands with action-handlers ([#1] [#764] [#1149])
* `.addCommand()` for adding a separately configured command ([#764] [#1149])
* allow a non-executable to be set as the default command ([#742] [#1149])
* implicit help command when there are subcommands (previously only if executables) ([#1149])
* customise implicit help command with `.addHelpCommand()` ([#1149])
* display error message for unknown subcommand, by default ([#432] [#1088] [#1149])
* display help for missing subcommand, by default ([#1088] [#1149])
* combined short options as single argument may include boolean flags and value flag and value (e.g. `-a -b -p 80` can be written as `-abp80`) ([#1145])
* `.parseOption()` includes short flag and long flag expansions ([#1145])
* `.helpInformation()` returns help text as a string, previously a private routine ([#1169])
* `.parse()` implicitly uses `process.argv` if arguments not specified ([#1172])
* optionally specify where `.parse()` arguments "from", if not following node conventions ([#512] [#1172])
* suggest help option along with unknown command error ([#1179])
* TypeScript definition for `commands` property of `Command` ([#1184])
* export `program` property ([#1195])
* `createCommand` factory method to simplify subclassing ([#1191])
### Fixed
* preserve argument order in subcommands ([#508] [#962] [#1138])
* do not emit `command:*` for executable subcommands ([#809] [#1149])
* action handler called whether or not there are non-option arguments ([#1062] [#1149])
* combining option short flag and value in single argument now works for subcommands ([#1145])
* only add implicit help command when it will not conflict with other uses of argument ([#1153] [#1149])
* implicit help command works with command aliases ([#948] [#1149])
* options are validated whether or not there is an action handler ([#1149])
### Changed
* *Breaking* `.args` contains command arguments with just recognised options removed ([#1032] [#1138])
* *Breaking* display error if required argument for command is missing ([#995] [#1149])
* tighten TypeScript definition of custom option processing function passed to `.option()` ([#1119])
* *Breaking* `.allowUnknownOption()` ([#802] [#1138])
* unknown options included in arguments passed to command action handler
* unknown options included in `.args`
* only recognised option short flags and long flags are expanded (e.g. `-ab` or `--foo=bar`) ([#1145])
* *Breaking* `.parseOptions()` ([#1138])
* `args` in returned result renamed `operands` and does not include anything after first unknown option
* `unknown` in returned result has arguments after first unknown option including operands, not just options and values
* *Breaking* `.on('command:*', callback)` and other command events passed (changed) results from `.parseOptions`, i.e. operands and unknown ([#1138])
* refactor Option from prototype to class ([#1133])
* refactor Command from prototype to class ([#1159])
* changes to error handling ([#1165])
* throw for author error, not just display message
* preflight for variadic error
* add tips to missing subcommand executable
* TypeScript fluent return types changed to be more subclass friendly, return `this` rather than `Command` ([#1180])
* `.parseAsync` returns `Promise<this>` to be consistent with `.parse()` ([#1180])
* update dependencies
### Removed
* removed EventEmitter from TypeScript definition for Command, eliminating implicit peer dependency on `@types/node` ([#1146])
* removed private function `normalize` (the functionality has been integrated into `parseOptions`) ([#1145])
* `parseExpectedArgs` is now private ([#1149])
### Migration Tips
If you use `.on('command:*')` or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
If you use `program.args` or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.

## [4.0.0] (2019-11-02)
### Added
* automatically wrap and indent help descriptions for options and commands ([#1051])
* `.exitOverride()` allows override of calls to `process.exit` for additional error handling and to keep program running ([#1040])
* support for declaring required options with `.requiredOptions()` ([#1071])
* GitHub Actions support ([#1027])

* *Breaking* Commander is only officially supported on Node 8 and above, and requires Node 6 ([#1053])
### Fixed
* *Breaking* keep command object out of program.args when action handler called ([#1048])
* also, action handler now passed array of unknown arguments
* complain about unknown options when program argument supplied and action handler ([#1049])
* this changes parameters to `command:*` event to include unknown arguments
* removed deprecated `customFds` option from call to `child_process.spawn` ([#1052])
* rework TypeScript declarations to bring all types into imported namespace ([#1081])
### Migration Tips
#### Testing for no arguments
If you were previously using code like:
```js
if (!program.args.length) ...
```
a partial replacement is:
```js
if (program.rawArgs.length < 3) ...
```

### Changed
* consistently use `const` rather than `var` in README ([#1026])
### Fixed
* help for sub commands with custom executableFile ([#1018])
## [3.0.0] / 2019-08-08
* Add option to specify executable file name ([#999])
* e.g. `.command('clone', 'clone description', { executableFile: 'myClone' })`
* Change docs for `.command` to contrast action handler vs git-style executable. ([#938] [#990])
* **Breaking** Change TypeScript to use overloaded function for `.command`. ([#938] [#990])
* Change to use straight quotes around strings in error messages (like 'this' instead of `this') ([#915])
* Add TypeScript "reference types" for node ([#974])
* Add support for hyphen as an option argument in subcommands ([#697])
* Add support for a short option flag and its value to be concatenated for action handler subcommands ([#599])
* e.g. `-p 80` can also be supplied as `-p80`
* Add executable arguments to spawn in win32, for git-style executables ([#611])
* e.g. `node --harmony myCommand.js clone`
* Add parent command as prefix of subcommand in help ([#980])
* Add optional custom description to `.version` ([#963])
* e.g. `program.version('0.0.1', '-v, --vers', 'output the current version')`
* Add `.helpOption(flags, description)` routine to customise help flags and description ([#963])
* e.g. `.helpOption('-e, --HELP', 'read more information')`
* Fix behavior of --no-* options ([#795])
* can now define both `--foo` and `--no-foo`
* **Breaking** custom event listeners: `--no-foo` on cli now emits `option:no-foo` (previously `option:foo`)
* **Breaking** default value: defining `--no-foo` after defining `--foo` leaves the default value unchanged (previously set it to false)
* allow boolean default value, such as from environment ([#987])
* Increment inspector port for spawned subcommands ([#991])
* e.g. `node --inspect myCommand.js clone`
### Migration Tips
The custom event for a negated option like `--no-foo` is `option:no-foo` (previously `option:foo`).
```js
program
.option('--no-foo')
.on('option:no-foo', () => {
console.log('removing foo');
});
```
When using TypeScript, adding a command does not allow an explicit `undefined` for an unwanted executable description (e.g
for a command with an action handler).
```js
program
.command('action1', undefined, { noHelp: true }) // No longer valid
.command('action2', { noHelp: true }) // Correct
```
