跪求大仙指点，除了去suunto指定的维护店升级，有没有firmware流出，自己可以升级么？现在好像是1.2.9了
Addition of DIVE mode OFF and FREE
Addition of Apnea timer
D6i upgraded from 2 to 3 nitrox mixes per dive
Remaining air time display added to D9tx (already in D6i and D4i)
Ability to switch Remaining air time display ON or OFF
Improved time alarm functions – Off/Once/Weekdays/Everyday
貌似最有用的也就是dive的关闭模式了，多少能省点电吧
