SPI driver has been postponed to the next release. SPIFFS integration has also been moved to a lower priority because we see that a few projects have already integrated SPIFFS successfully (e.g. nodemcu, Lua-RTOS). Instead, we will be adding support for ULP coprocessor programming in 1.0 (which was not part of the original plan). OTA API is already in master now, along with partition API. There are a few bugs there mentioned in the other topics on this forum, we have a fix up for review already, it should make it into 1.0. RF analysis and testing features were not part of 1.0 release plan. If you need more information about ATE mode at this time, please contact Espressif directly. WiFi TX power can be set at compile time using menuconfig. We will have an API to set it at run time, but this feature is currently in backlog and i can't give you a timeline for it. As mentioned in my previous message, our plan is to finalize 1.0 version on Friday.
