Available via npm install jspm@beta.

For usage instructions, see the jspm 0.17 beta guide.

Breaking Changes in jspm 0.17

• When updating to jspm 0.17, jspm 0.16 projects will run through an automated upgrade process.
• defaultJSExtensions is now disabled and cannot be enabled for this version of jspm. Package configuration is now the primary mechanism for ensuring a defaultExtension.
• config.js is now called jspm.config.js and works alongside a new separate jspm.browser.js config file
• jspm install github:x/y now installs into the default alias y not x/y
• Registry API changes (with backwards compatibility warnings):
  • The build hook has been renamed to processPackage taking new arguments (https://github.com/jspm/jspm-cli/blob/0.17/docs/registry-api.md#processpackage-packageconfig-packagename-packagedir-optional)
  • packageFormat has been renamed to packageNameFormats using wildcard syntax over regular expressions (https://github.com/jspm/jspm-cli/blob/0.17/docs/registry-api.md#static-packagenameformats)
• By default transpilers are plugins, with the init process providing the standard plugins for Traceur, Babel and TypeScript. jspm dl-loader babel is no longer supported and this command only downloads the loader files.
• The GitHub registry will always download the git tree tag or branch directly instead of checking for uploaded release archive assets. As a result GitHub API credentials are no longer necessary.
• All overrides are all checked in to the package.json file to guarantee reproducibility.
• jspm setmode remote has been disabled until the jspm registry can be upgraded to the 0.17 version.
