CSS3 is an upgrade from CSS2. Where CSS2 was one large specification (like one big file), CSS3 is comprised of multiple files, called modules. Modules allow each browser to interpret different declarations, such as border-radius. Where, in CSS2, this did not exist and could not exist until it was published as a Cascading Style Sheet recommendation. The benefit to using modules (multiple files) is that many new styles can be created and supported in different browsers. The negative, however, is that modules are sometimes unstable. What this all means, is that CSS3 is much more open to change and will continue to evolve until it’s reached it’s maximum potential, but with it’s open mind to change comes some stability issues. There is a CSS4, its still a draft though and no major browser supports this.
