The California Codes as hosted by LawServer come from the online database maintained by California legislature, and are updated after the legislature updates its database. The legislature does not immediately update the Codes when a new law is enacted, however. So to bring your research up to the date it is sometimes necessary to look for laws enacted since the latest versions of the Codes were published. That information is available here.
