jelly bean was released as an OTA for the GS2 recently. what's new ?

are there any new features that ics never had ? or any differences in stock apps such as the memo, calculator, calendar etc



also how do I get the old calender back as it displayed all the public holidays and it appears this new stock calender does/dose not, or can I enable this as a setting ?



the same old story, family members S2 (i still have my EVO)
