The fifth beta release of Tapestry 4.0 is now available. Tapestry is a component based web application framework that provides lots of functionality with minimal Java coding, and creates an environment that supports high levels of reuse. This is another a bug fix release, building on the beta-4 release. Many of the fixes in this release were improvements to client-side JavaScript, including client-side input validation. The way Tapestry forms client-side element ids is now XHTML conformant (no use of the dollar sign, no leading underscores). The Form component has a new listener parameter, success, that is only invoked when validation is successful. A full listing of bugs fixes is available in the change log. Tapestry is provided as a combined binary/source distribution, and a separate documentation distribution.

JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions, including JMS, LDAP, SMTP, JDBC, SOAP etc. Release 2.1 includes an additional script format - smaller, more compact, more readable - based on Xstream. There are updates to the JMS, JDBC, WSDL and XML processing. Also a new config item, CSV DataSet for easier test parameterisation. For a full description, see the history of changes.

The latest release of the HiveMind services and configuration microkernel progresses towards a final 1.1 release. A few minor bugs were fixed, and the build environment was improved. More importantly, there have been significant improvements to the documentation, care of newest committer Achim Hugen.
