SL808x Firmware Recommendation

SL8080T & SL8082T came with R7.52. Our Open AT app does TCP to a remote server & RS232 to embedded PIC, plus GPS. All data, no calls. Is there a pressing reason to go to 7.54? (I saw that the 7.54 upgrade requires going thru 7.53 & would really like to avoid it.)

Thx.
