Are there any example of CSS hacks which were working before but not after new version or patch released?

Are there any example of CSS hacks which were working before new version or patch released?

Is it ever happened?

mainly i want to know for 开发者_高级运维IE, but would like to know cases of other browsers also.

my question is not about "CSS hacks vs IE conditional css"

Yes, there are. On the page CSS Compatibility in Internet Explorer 7 you can find six examples of CSS hacks that stopped working when IE7 was released.
