After months of testing,WordPress 3.4 is finally working officially.It has a code name “Green” in honor of guitarist Grant Green.
In this updated version,the biggest change for users is Theme Customizer which allows you edit your theme with live preview.You can change color,background,custom image of header etc. in the customizer.
Another change is Tweets could be embed in posts now.Just insert a permanent link of your tweet in a post and it would be embedded beautifully.
Lastly,image captions have been improved to allow HTML,like links,in them.
The upgrade process is simple as usual.Get into your update settings,backup your data and click ‘Update now’.Then it will be completed within 5 mins normally.Of course,manual installation will be an option too.You could download WordPress 3.4 here.
