([#​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` ## Example Breaking Changes 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 ```js program .command('action1', undefined, { noHelp: true }) // No longer valid .command('action2', { noHelp: true }) // Correct ```
