The Lift team is pleased to announce Lift 2.2. In the three months since the 2.1 release, the team has closed over 100 tickets and made significant improvements to Lift based on community feedback.

Lift is an elegant, expressive framework that allows any size team build and maintain secure, highly interactive, scalable web applications quickly and efficiently. Lift is built on Scala and compiles to JVM byte-code. Lift applications deploy as WAR files on popular application servers and web containers including Jetty, Glassfish and Tomcat. Lift applications can be monitored and managed with the same proven infrastructure used to manage and monitor any Java web application. Lift is open source licensed under an Apache 2.0 license.

Lift features include:

  • Community... the Lift community is 2,400 members strong, super-active and always there to help with questions
  • Best Comet (server-push) support that allows the creation of dynamic application such as Novell Vibe
  • Super simple Ajax for creating highly interactive web applications without worrying about HTTP plumbing
  • Secure by default... Lift apps are resistant to the OWASP top 10 vulnerabilities including XSS, XSRF, and parameter tampering
  • Concise and Maintainable... Lift apps typically contain fewer lines of code than corresponding Rails apps, yet are type safe so that many errors are flagged by the compiler
  • Scalable... Lift apps scale to millions of users across many servers, yet are highly efficient for single-box implementations
  • Compatible... Lift apps can take advantage of any Java library as well as the growing collection of Scala libraries

Lift 2.2 improvements include:

  • HTML5 Support: Lift supports parsing HTML5 input files and rendering HTML5 to the browser in addition to Lift’s XHTML support
  • Wiring: Spreadsheets meet web application yielding an automatic mechanism for updating dependent elements on a page, making it even easier to build dynamic apps with Lift
  • Wizard and Screen Improvements: Build complex screens more easily with new helper methods for creating form elements and improved life-cycle callbacks
  • CSS Selector Transforms Improvements: including appending attributes, multiple selectors applying to a single element, and element lifting
  • Support for migratory sessions: ContainerVars provide type-safe, guaranteed serializable session variables that can migrate across application servers in a cluster
  • Improved i18n: including per-page localization strings and localization strings and HTML stored in templates rather than Java resource files which makes editing much easier
  • Security Improvements: including creation of new sessions on login
  • MongoDB Improvements: performance improvements as well as new features
  • Support for Scala 2.8.1 as well as 2.8.0 and 2.7.7
