PhoneGap 2.x will include improvements such as enabling internationalization, adding a command line build tool, allowing native applications to close with Device.exitApp(), packaging plugins separately, and listing SMS messages. It will also thin out the PhoneGap client, support more platforms like Bada and MeeGo, address platform-specific UX concerns, and continue improving tools while focusing on performance and security. HTML5 polyfilling and other browser capabilities will also be addressed. The cadence for PhoneGap updates will be a major release every year.
