/** * Update WP-CLI to the latest release. * * Default behavior is to check the releases API for the newest stable * version, and prompt if one is available. * * Use `--stable` to install or reinstall the latest stable version. * * Use `--nightly` to install the latest built version of the master branch. * While not recommended for production, nightly contains the latest and * greatest, and should be stable enough for development and staging * environments. * * Only works for the Phar installation mechanism. * * ## OPTIONS * * [--patch] * : Only perform patch updates. * * [--minor] * : Only perform minor updates. * * [--major] * : Only perform major updates. * * [--stable] * : Update to the latest stable release. Skips update check. * * [--nightly] * : Update to the latest built version of the master branch. Potentially unstable. * * [--yes] * : Do not prompt for confirmation. * * ## EXAMPLES * * # Update CLI. * $ wp cli update * You have version 0.24.0. Would you like to update to 0.24.1? [y/n] y * Downloading from https://github.com/wp-cli/wp-cli/releases/download/v0.24.1/wp-cli-0.24.1.phar... * New version works.
