+## [9.0.0-0] (2021-12-22)
+
+### Added
+
+- simpler ECMAScript import ([#1589])
+- Option.preset() allows specifying value/arg for option when used without option-argument (especially optional, but also boolean option) ([#1652])
+- `.executableDir()` for custom search for subcommands ([#1571])
+- throw with helpful message if pass `Option` to `.option()` or `.requiredOption()` ([#1655])
+
+### Changed
+
+- *Breaking:* Commander 9 requires Node.js v12.20.0 or higher
+- update package-lock.json to lockfile@2 format ([#1659])
+- `showSuggestionAfterError` is now on by default ([#1657])
+- *Breaking:* default value specified for boolean option now always used as default value (see .preset() to match some previous behaviours) ([#1652])
+- default value for boolean option only shown in help if true/false ([#1652])
+- use command name as prefix for subcommand stand-alone executable name (with fallback to script name for backwards compatibility) ([#1571])
+- allow absolute path with `executableFile` ([#1571])
+- removed restriction that nested subcommands must specify `executableFile` ([#1571])
+
+### Fixed
+
+- option with optional argument not supplied on command line now works when option already has a value, whether from default value or from previous arguments ([#1652])
+
+### Removed
+
+- *Breaking:* removed internal fallback to `require.main.filename` when script not known from arguments passed to `.parse()` (can supply details using `.name()`, and `.executableDir()` or `executableFile`) ([#1571])
+
