Since a few days ago, you added a non-configurable text shadow to the widget text without warning. On widgets with dark text on light background (such as ours: #7A8FB6 on #ECF0F3), it makes the widget text look fuzzy, and ugly.
If you want to force such a change on your users, it should at least be configurable (including disabling it) since you can't be certain that it'll look good in every situation.
Thanks, Sergey.
We also realized that this was part of a bigger change in your script, which added an element to the top of the page. This briefly pushes our header down about 30 pixels, and causes a visible flicker when our page loads. We spent an hour trying to debug it before realizing it's was due to a UE change.
Please be very careful about making changes to your widget because it affects your customers' websites. At the very least, please send out a notification so if something goes wrong we can quickly troubleshoot it.
