Arduino IDE Beta 1.5.x ?

I've been using the 1.0 IDE, but see that the 1.5.x Beta's have been out a (long) time. Are they stable? Are most users on the official release or the Beta?

I am on Mac OS X if that makes a difference.

If you are using a 8 bit AVR arduino board then 1.0.5r2 is the current stable release. If you are using a 32 bit arduino board then `1.5.x is what you must run and it is still in beta. Eventually they will most likely be merged into a single stable release.

Hi,

I use currently the beta release (Arduino IDE Beta 1.5.6-r2) under Linux platform.

Here you can find more info about it:
