New additions to the Servoshell and underlying Servo rendering code allow for opening of multiple windows on the desktop. Long overdue but at least it now works.
Servo 0.0.4 also brings support for more CSS functionality, partial support for encoding sniffing, continued work on the SubtleCrypto API, dev tooling improvements, and continued enhancements around the embedding API.
Servo 0.0.4 also has landed various improvements for better performance and stability.
Downloads and more details on these December improvements to Servo can be found via the blog on Servo.org .
