Version 1.13 concentrates on bringing new flexibility into Doomsday's renderer. Under the hood we've also been reorganizing management of logical resources into a better shape for future needs.
Framebuffer effects. Doomsday can now use OpenGL shaders to post-process the rendered frames. In this release, we've applied this for libdoom's Invulnerability power-up effect.
Stereoscopic 3D. Support has been added for various stereoscopic rendering modes, including anaglyph, side-by-side, parallel and cross-eyed viewing.
Oculus Rift. Full support for playing all supported games using Oculus Rift, including head tracking and easy auto-configuration via the new 3D & VR settings dialog. The Windows and OS X packages include built-in support for Oculus Rift; on other platforms one must manually compile the engine using the Oculus SDK.
UI experience enhancements. Doomsday's UI renovation is still ongoing, and we've been fine-tuning the elements introduced so far. busy_mode is now better integrated into the rest of the UI (for instance, when loading a map) and widgets look and behave smoother, requiring less mouse clicking.
If you are upgrading an existing installation of Doomsday, note the following:
Big project management update: bug and feature tracking has been moved to our own Tracker. The biggest advantages are much-improved speed and a better interface for managing and browsing issues. We're very happy with the new tracker and hope it will give a boost for future development efforts.
