New page:
== Tapestry 4.1.2 ==
Development of the 4.1.X series continues with what are more or less largely feature improvements / bug fixes / elimination of "quirks". This release is currently only waiting for the new OGNL features to stabilize - which we hope happens soon. (maybe 2-3 more weeks if you are feeling optimistic)

=== OGNL 2.7 ===
One of the feature improvements involved improving the runtime performance of a critical library used to resolve java object property expressions. 

Most of the details can be found in either links [http://blog.opencomponentry.com/2007/03/05/tentative-ognl-27-snapshot-release-out-to-blow-up-a-project-near-you/ OGNL 2.7-SNAPSHOT released], [http://blog.opencomponentry.com/2007/01/14/new-ognl-release-on-the-horizon-its-faster/ new ognl release coming..]. The gist of it is that a new bytecode compilation step has been added to the process to translate the ast generated object graph from typical ognl expressions into their pure(er) java bytecode form - making for a much faster runtime. 

It is expected that these changes will also eventually make their way into [http://struts.apache.org/2.0.6/ Struts 2]. Specifically - Patrick Lightbody from opensymphony / Jesse have been collaborating on bringing the project forward and outlining features that more projects need with newer jvm's. (such as [http://opensymphony.com/xwork XWork] / webwork / struts2 / etc...) There is even speculation that should the 1.5 java.lang.Type support come in Tapestry 5 may think about using them.
