+## [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.
+
+If you want to continue combining short options with optional values as though they were boolean flags, set `combineFlagAndOptionalValue(false)`
+to expand `-fb` to `-f -b` rather than `-f b`.

+* 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) ...
+```

-You write code to describe your command line interface.
-Commander looks after parsing the arguments into options and command-arguments,
-displays usage errors for problems, and implements a help system.
-
-Commander is strict and displays an error for unrecognised options.
-The two most used option types are a boolean option, and an option which takes its value from the following argument.
-
-Example file: [split.js](./examples/split.js)
-
-```js
-const { program } = require('commander');
-
-program
-  .option('--first')
-  .option('-s, --separator <char>');
-
-program.parse();
-
-const options = program.opts();
-const limit = options.first ? 1 : undefined;
-console.log(program.args[0].split(options.separator, limit));
-```
-
-```console
-$ node split.js -s / --fits a/b/c
-error: unknown option '--fits'
-(Did you mean --first?)
-$ node split.js -s / --first a/b/c
-[ 'a' ]
-```
-
-Here is a more complete program using a subcommand and with descriptions for the help. In a multi-command program, you have an action handler for each command (or stand-alone executables for the commands).
-
-Example file: [string-util.js](./examples/string-util.js)
-
-```js
-const { Command } = require('commander');
-const program = new Command();
-
-program
-  .name('string-util')
-  .description('CLI to some JavaScript string utilities')
-  .version('0.8.0');
-
-program.command('split')
-  .description('Split a string into substrings and display as an array')
-  .argument('<string>', 'string to split')
-  .option('--first', 'display just the first substring')
-  .option('-s, --separator <char>', 'separator character', ',')
-  .action((str, options) => {
-    const limit = options.first ? 1 : undefined;
-    console.log(str.split(options.separator, limit));
-  });
-
-program.parse();
-```
-
-```console
-$ node string-util.js help split
-Usage: string-util split [options] <string>
-
-Split a string into substrings and display as an array.
-
-Arguments:
-  string                  string to split
-
-Options:
-  --first                 display just the first substring
-  -s, --separator <char>  separator character (default: ",")
-  -h, --help              display help for command
-
-$ node string-util.js split --separator=/ a/b/c
-[ 'a', 'b', 'c' ]
-```
-
-More samples can be found in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory.
-
 ## Declaring _program_ variable
 
 Commander exports a global object which is convenient for quick programs.
 This is used in the examples in this README for brevity.
 
 ```js
-// CommonJS (.cjs)
 const { program } = require('commander');
+program.version('0.0.1');
 ```
 
 For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
 
 ```js
-// CommonJS (.cjs)
 const { Command } = require('commander');
 const program = new Command();
-```
-
-```js
-// ECMAScript (.mjs)
-import { Command } from 'commander';
-const program = new Command();
-```
-
-```ts
-// TypeScript (.ts)
-import { Command } from 'commander';
-const program = new Command();
+program.version('0.0.1');
 ```
 
 ## Options
 
 Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|').
 
-The parsed options can be accessed by calling `.opts()` on a `Command` object, and are passed to the action handler.
-
-Multi-word options such as "--template-engine" are camel-cased, becoming `program.opts().templateEngine` etc.
+The options can be accessed as properties on the Command object. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. See also optional new behaviour to [avoid name clashes](#avoiding-option-name-clashes).
 
-An option and its option-argument can be separated by a space, or combined into the same argument. The option-argument can follow the short option directly or follow an `=` for a long option.
-
-```sh
-serve -p 80
-serve -p80
-serve --port 80
-serve --port=80
-```
+Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
+For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
 
 You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
 
-By default options on the command line are not positional, and can be specified before or after other arguments.
-
-There are additional related routines for when `.opts()` is not enough:
-
-- `.optsWithGlobals()` returns merged local and global option values
-- `.getOptionValue()` and `.setOptionValue()` work with a single option value
-- `.getOptionValueSource()` and `.setOptionValueWithSource()` include where the option value came from
+Options on the command line are not positional, and can be specified before or after other arguments.
 
 ### Common option types, boolean and value
 
 The two most used option types are a boolean option, and an option which takes its value
-from the following argument (declared with angle brackets like `--expect <value>`). Both are `undefined` unless specified on command line.

 ## Commands
 
 You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)).
 
-In the first parameter to `.command()` you specify the command name. You may append the command-arguments after the command name, or specify them separately using `.argument()`. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.

+### Action handler (sub)commands
 
-Example file: [arguments-extra.js](./examples/arguments-extra.js)
+You can add options to a command that uses an action handler.
+The action handler gets passed a parameter for each argument you declared, and one additional argument which is the
+command object itself. This command argument has the values for the command-specific options added as properties.
 
 ```js
-program
-  .addArgument(new commander.Argument('<drink-size>', 'drink cup size').choices(['small', 'medium', 'large']))

-    console.log(`${first} + ${second} = ${first + second}`);
+  .command('rm <dir>')
+  .option('-r, --recursive', 'Remove recursively')
+  .action(function (dir, cmdObj) {
+    console.log('remove ' + dir + (cmdObj.recursive ? ' recursively' : ''))
   })
-;
-```
 
-### Action handler
-
-The action handler gets passed a parameter for each command-argument you declared, and two additional parameters
-which are the parsed options and the command object itself.
-
-Example file: [thank.js](./examples/thank.js)
-
-```js
-program
-  .argument('<name>')
-  .option('-t, --title <honorific>', 'title to use before name')
-  .option('-d, --debug', 'display some debugging')
-  .action((name, options, command) => {
-    if (options.debug) {
-      console.error('Called %s with options %o', command.name(), options);
-    }
-    const title = options.title ? `${options.title} ` : '';
-    console.log(`Thank-you ${title}${name}`);
-  });
-```
-
-If you prefer, you can work with the command directly and skip declaring the parameters for the action handler. The `this` keyword is set to the running command and can be used from a function expression (but not from an arrow function).
-
-Example file: [action-this.js](./examples/action-this.js)
-
-```js
-program
-  .command('serve')
-  .argument('<script>')
-  .option('-p, --port <number>', 'port number', 80)
-  .action(function() {
-    console.error('Run script %s on port %s', this.args[0], this.opts().port);
-  });
+program.parse(process.argv)

-You can override any method on the [Help](./lib/help.js) class. There are methods getting the visible lists of arguments, options, and subcommands. There are methods for formatting the items in the lists, with each item having a _term_ and _description_. Take a look at `.formatHelp()` to see how they are used.

-### Parsing Configuration
+### Avoiding option name clashes
 
-If the default parsing does not suit your needs, there are some behaviours to support other usage patterns.
+The original and default behaviour is that the option values are stored
+as properties on the program, and the action handler is passed a
+command object with the options values stored as properties.
+This is very convenient to code, but the downside is possible clashes with
+existing properties of Command.
 
-By default program options are recognised before and after subcommands. To only look for program options before subcommands, use `.enablePositionalOptions()`. This lets you use
-an option for a different purpose in subcommands.
+There are two new routines to change the behaviour, and the default behaviour may change in the future:
 
-Example file: [positional-options.js](./examples/positional-options.js)
+- `storeOptionsAsProperties`: whether to store option values as properties on command object, or store separately (specify false) and access using `.opts()`
+- `passCommandToAction`: whether to pass command to action handler,
+or just the options (specify false)
 
-With positional options, the `-b` is a program option in the first line and a subcommand option in the second line:
-
-```sh
-program -b subcommand
-program subcommand -b
-```
+Example file: [storeOptionsAsProperties-action.js](./examples/storeOptionsAsProperties-action.js)
 
-By default options are recognised before and after command-arguments. To only process options that come
-before the command-arguments, use `.passThroughOptions()`. This lets you pass the  arguments and following options through to another program
-without needing to use `--` to end the option processing.
-To use pass through options in a subcommand, the program needs to enable positional options.
-
-Example file: [pass-through-options.js](./examples/pass-through-options.js)
-
-With pass through options, the `--port=80` is a program option in the first line and passed through as a command-argument in the second line:
-
-```sh
-program --port=80 arg
-program arg --port=80
-```
-
-By default the option processing shows an error for an unknown option. To have an unknown option treated as an ordinary command-argument and continue looking for options, use `.allowUnknownOption()`. This lets you mix known and unknown options.
-
-By default the argument processing does not display an error for more command-arguments than expected.
-To display an error for excess arguments, use`.allowExcessArguments(false)`.
-
-### Legacy options as properties
+```js
+program
+  .storeOptionsAsProperties(false)
+  .passCommandToAction(false);
 
-Before Commander 7, the option values were stored as properties on the command.
-This was convenient to code but the downside was possible clashes with
-existing properties of `Command`. You can revert to the old behaviour to run unmodified legacy code by using `.storeOptionsAsProperties()`.
+program
+  .name('my-program-name')
+  .option('-n,--name <name>');
 
-```js
 program
-  .storeOptionsAsProperties()
-  .option('-d, --debug')
-  .action((commandAndOptions) => {
-    if (commandAndOptions.debug) {
-      console.error(`Called ${commandAndOptions.name()}`);
-    }
+  .command('show')
+  .option('-a,--action <action>')

+    console.log(options.action);
