EG meeting publish on web site

by Antoine Sabot-Durand

Hi all, Just to let you know that I published meeting minutes on the website. in the news section [1] I also did some minor change to the site : - Removed « major issues section » which wasn’t working (will put it back after I figured out how to make it work again) - Added link to G+ and Twitter Before adding tutorial, howtos and a page pouting CDI initiatives and extensions, I plan to do a little more work on UI and navigation. Roughly, I plan to change the navigation with a more classical navbar on the top, Upgrade to awestruct 0.5.3 and bootstrap 3.x (started the migration) and integrated our ml from Nabble embedded or an other service if you know a better one. Your input, ideas, help is off course most welcome. Antoine [1] http://www.cdi-spec.org/news/

[JBoss JIRA] (CDI-401) Clarify the meaning of "bean class local view"
