0.4.3 Firmware Release for Photon/P1

I noticed recently that itoa() now compiles without calling extern

extern "C" char* itoa(int a, char* buffer, unsigned char radix);

I didn’t see anything in the recent firmware release notes…

Is there a page somewhere that I need to watch for Particle Dev update notes?

(Also, I noticed two of my Photons hit a major behavioral roadblock, not staying connected to WiFi… It started about a week or two ago. I just got home to check it out and had to update the firmware to get everything back working correctly. Were there recent updates to the Particle Cloud that were not backward compatible for all Particle Functions?)
