Some highlights of this release:

Supports Twitter Bootstrap version 3 Wt now supports the latest version of Twitter Bootstrap, next to the already existing Bootstrap 2 theme support. We still default to Twitter Bootstrap 2, as bootstrap 3 "changed everything". While the theme implementation absorbs already quite a bit of these changes, there will be some porting effort to migrate to version 3. You should consider using version 3 for new developments though, at least if the restricted browser (i.e. most notably no more IE7) support fits your requirements.

To use Twitter Bootstrap effectively, you will need to learn about the markup that is expected, especially related to layout and its responsive design features.

Server-side (fallback) option for WGLWidget Since some time (Wt 3.1.7 from 2010!), WGLWidget provides support for client-side 3D graphics using WebGL in C++ Wt, and with Microsoft finally endorsing WebGL in IE11 the future of browser-based 3D Graphics looks more than promising.

In this release, WGLWidget received a decent update. We’ve added a flag to render server-side (using OpenGL) in an off-screen buffer, as a portable solution. This may also be convenient when scene complexity is so high that downloading the entire scene to a client is less efficient than rendering things server-side (using a graphics card in the server).

Until now, JWt support for WGLWidget was lacking, but this release makes up for it with feature parity between C++ and Java releases (using jogl for the server-side implementation).

3D Graphics Library Putting WGLWidget to use, 3D charts have been implemented aside the existing 2D charts.
