Welcome Zotonic 0.12.0, released on October 8, 2014.
This release has been released on the same day as Release 0.11.0. The main difference between these 2 releases is that in 0.12, Bootstrap has been upgraded on all templates. 0.11 was released as a feature release with all major improvements of the last 6 months excluding Bootstrap 3 support.
Bootstrap CSS version 3
Zotonic has been switched over to the latest version of the Bootstrap
Framework, version 3.2.0. When you are using Zotonic’s
mod_bootstrap or when you have customized the admin templates, you
will need to update your templates.
