RIM just posted on their DevBlog that they just launched and update to the BlackBerry WebWorks SDK Beta 3.
You can pick up the update at this LINK
Note from RIM: Important architectural changes have been implemented in v184.108.40.206 of the BlackBerry WebWorks SDK, so developers will need to re-compile existing applications using this SDK in order for them to successfully run on the new BlackBerry® Tablet OS simulator v.0.9.4.
What’s New: Our development teams have been very active since the last release, and have made some terrific enhancements in the capabilities, stability and performance of the Beta3 version of the SDK. Some notable improvements include
Code signing enabled – you can now secure your application using the BlackBerry code signing process for BlackBerry Tablet OS. Learn about code signing Here
AJAX support for local context. This fix improves the quality of support for using AJAX to retrieve local resources. A benefit of this fix includes improved support on the BlackBerry® PlayBook™ tablet for Java
Loading screen image – Developers can define a loading screen and transition effect in their config.xml file to improve the user experience during application startup.
Major improvements in Mac support – Absolute paths now allowed in ZIP archive; _MACOSX folder no longer being included in BAR file; Format of bbwp command line arguments changed from “-“ to “/”.
