One more issue which we are seeing in RC3:
We have a label with an image which used to work fine before both in SC and WC. The text for the label uses HTML and is (this was our workaround to keep the image and text together on the web client):
<html><body><img src="media:///home.png" height="16px" width="16px"><span style="display: inline;"> Home</span></body></html>
After updating to RC3, the Smart Client still shows the image correctly, however in the Web Client it displays the actual HTML code (see attached screen-shots)
