In native Android calendar app RFC 2445 protocol is used to create .ics files. I found in some blogs that RFC 2445 is replaced with RFC 5545. Can any one please tell me what are the extra features in RFC 5545 and how it is different from RFC 2445?

Why don't you compare RFC 2445 with RFC 5545?
In particular, RFC 5545's cover page states that it obsoletes RFC 2445, and its table of contents lists:
Appendix A. Differences from RFC 2445 . . . . . . . . . . . . . 169
A.1. New Restrictions . . . . . . . . . . . . . . . . . . . . 169
A.2. Restrictions Removed . . . . . . . . . . . . . . . . . . 169
A.3. Deprecated Features . . . . . . . . . . . . . . . . . . . 169
(The ToC is inaccurate; the information appears on page 167. The changes cited are all minor (or, at least, succinct) as far as I can see.)
