As per the subject heading, Meade have released LX600 firmware update to version 1.1h to correct the rollover problem, if your telescope fell victim. It does not claim to address any other issues.
Refer to Meade's website for further details.
I am happy with Andrew Johansen's previously released firmware fix, version 1.1G, which also addresses a couple of other bugs, as well as the GPS Rollover issue, so I will stick with that.
Andrew's firmware is probably the better option. Andrews patch available from the Starpatch website.
