ESPtool 0.4.6 no longer working

[sticilface]

0.4.5 works fine. 0.4.6 does not flash my node-mcu 0.9.
normally works under generic esp8266, but no longer does.
Does not working selecting node-mcc board either.

copying 0.4.5 into the place of 0.4.6 works immediately.
Using on Mac.

I have changed the reset method for NodeMCU 1.0 from ck to nodemcu, but forgot to change it for NodeMCU 0.9. This is now fixed, thanks for noting.

I can confirm that using 1.0 board works. so i'll close it.
