Governor limit for Field Describes and Picklist Describe is increased from 10 to 100.
This limit is mostly encountered when we are displaying more than 10 picklist on visual force page which is not binded with <apex:inputField> tag. We sometimes prefer <apex:inputText> rather <apex:inputField> to avoid field security restriction on profile level. For this if we want to display picklist values on visualforce page we have to describe picklist values. Before the last release picklist describe limit was 10 so we have to describe first 10 picklist values in one call, then hit the action function for the next 10 picklist values which decrease the performance of the page. But now the limit is hiked to 100.
Hope this info is useful.
