Apologies for neglecting the portal space, after the big release we've been heads down keeping up with demand. However, there are a lot of new happenings in the WebSpace!
There have been several new items in the development space. Cheten has done a nice writeup of support for Liferay Hooks Plugins in WebSpace's Portal Pack. In addition to hooks, work is almost complete on the Theme Builder, allowing custom themes to be developed in NetBeans and deployed to WebSpace Server and Liferay. Combining these with existing features like eventing (Vikas has done a nice writeup on this), you can do all of your WebSpace Server development without leaving the comfort of your IDE.
Also, don't forget that Portal Pack is also supported on Eclipse!
