Update to v1.1.1 aithinker on cactus micro r2

I found this link http://wiki.aprbrother.com/wiki/Firmware_For_ESP8266

I recently bought 2 catus micro r2. It states firmware needs at least 1Megabyte to update. Is this already on micro? Should I stay with v0.9? Any improvements? Sorry for so many questions just not sure what to do spend alot of time trying to find out and just wanna get to programming! Thanks!

If the original firmware works fine, you don’t need upgrade to v1.1.1. The recently cactus micro should have 1M bytes flash already.
