From the Notes:
2.0 What’s New
Notable fixes/changes in version 11.0 (Build 256)
* Fixed a bug that could cause a crash when displaying event properties for 3D clips from a Sony TD10 camera.
* Fixed a bug that could cause text from the Titles & Text plug-in to drift after dragging the text in the Video Preview window.
* Fixed a bug that could cause line breaks in the Titles & Text plug-in to preview with incorrect line spacing.
* Fixed a bug that could cause an error when rendering a Sony AVC file with a bit rate of less than 25 Mbps.
* Fixed a bug that could cause MVC clips from a Sony TD10 camera to be imported incorrectly from the Device Explorer.
* Fixed a bug that could cause Vegas Movie Studio to hang when previewing MTS files in the Trimmer window.
* Added Russian-language support to Vegas Movie Studio HD.
Notable fixes/changes in version 11.0 (Build 247)
* The Burn Blu-ray Disc feature has been updated for compliance with the Blu-ray Disc specification. You can render 3D projects to a Blu-ray 3D Disc image file (.iso) from the timeline (Tools > Burn Disc > Blu-ray Disc). This feature is intended for commercial BD-ROM preparation testing.
I have to say that I am positively impressed by the number of patches released by Sony.
The SW is now very stable and many issues have been fixed.
Thumbs up!
@vkmast while updating from 220 to 256 I lost the contents of the Help wizard, so I had to uninsatall and reinstall, now it seems ok. The update from 247 to 256 presumably does not cause any loss.
