UPDATE: Six new gun restrictions became law under legislation signed by California Gov. Jerry Brown. In all, the Democratic governor signed six of the 11 gun-related bills that landed on his desk the day before following a series of votes in the State Senate and Assembly.

A California legislative panel has approved seven gun-control bills.

Democrats on the Senate Public Safety Committee voted Tuesday to require that people who make homemade guns get a background check and apply for a serial number. Senate President Pro Tem Kevin de Leon says the bill would help police track guns used in crimes. Democratic Gov. Jerry Brown vetoed a similar measure in 2014.

The committee also approved a bill that seeks to get around a court order barring enforcement of a 2009 law requiring stores to keep records on purchases of handgun ammunition.

Lawmakers also backed a ban on ammunition magazines that hold more than 10 rounds and approved creating a firearm violence research center at the University of California.

Here's a list of the bills approved by the committee:
