Lots of positives from my first try with OS 2.0.0-RC.4:
+++ WiFi (on Photon) now seems to behave correctly in all the scenarios tested so far
Not a very scientific evaluation - wondering what others have found?
Some example warnings? What seems legit often depends on subjective interpretation 
I was rushing to post - here are the warnings from the compile - nextTime is declared as char nextTime[6];
-base.ino:19276:46: warning: '%02i' directive output may be truncated writing between 2 and 11 bytes into a region of size 6 [-Wformat-truncation=]
19276 | snprintf(nextTime, sizeof(nextTime), "%02i:%02i", _hr, _min);
-base.ino:19276:46: note: directive argument in the range [-1073741839, 1073741843]
-base.ino:19276:46: note: directive argument in the range [-30, 30]
-base.ino:19276:17: note: 'snprintf' output between 6 and 16 bytes into a destination of size 6
19276 | snprintf(nextTime, sizeof(nextTime), "%02i:%02i", _hr, _min);
Always welcome your insight on these matters.
I can add that I have now seen the memory usage for 2.0.0-RC.4 is slightly less than 1.4.4 - so that is another +ve.
These warnings are legit since the compiler doesnāt know that your _hr and _min will only ever be 0ā¦23 and 0ā¦59 respectively. It will go with the full range of the given data type and hence must assume you may end up losing āvaluableā information when at least one of the values would require more than two digits.
Warnings are meant to flag potentially problematic regions for the programmer to make reconsider or just accept the warning.
IIRC, if one once to be very āpedanticā and get rid of all warnings you may even be able to tell the compiler to not flag this for a specific instruction since you know itāll be fine.
But donāt ask me how itās done with this version of GCC
So there is nothing really I can do to silence these warnings - which are correct but āover protectiveā?
As I said, there are possibilities
This might work (or not - 
)
Having tried a few other apps I can see the warning āfine combā is going to be a feature!
I thought there might have been more feedback on experience with this OS??
@mstanley thanks for help on support ticket about an odd WiFi behaviour problem since OS after 0.8.0 - 2.0.0-rc.4 appears to have cured it, increased App Flash usage accepted if that is the cost.
