Has anyone bothered to update their ZS3/TS7 to firmware v1.3? According to Panasonic's website, this version "optimizes the software." Aside from the "third-party battery debate," is there *any* advantage to v1.3 over v1.2? I can't seem to find any favorable opinions, in any forum, for v1.3 (nor v1.2, for that matter)!Regards,FirmWhere?
