I've stuck with IDE 22 for ages now
seems to do everything I want/need (as far as I can tell)
what does the committee think of 1.0 now it's been out in the field for a while now?
are there any issues/gotchas?
what about memory utilisation?
appreciate your thoughts...
Well you are going to have to grasp the nettle sooner or later. I think that most of the things that are going to be changed have been changed by now and most of the issues are understood so there is not match gain in waiting now.
Some libraries still #include WProgram.h, and have to be updated. This is the only issue I found so far (but TBH I've not tried all of my previous sketches / libraries with 1.0).
oki doki
I'll give it a whirl
I'll try and keep a log in case anything interesting happens
well ok so far
the main sketch that I was nervous about didn't need too much surgery
main change was from using SoftwareSerial as BYTE is no longer supported
made the suggested change to Serial.write() and it - er well it failed badly!
fortunately I recognised the symptoms as I had seen them before
so I moved all the strings by wrapping F() around them
phew all working again!
couple of observations:
a) it would be nice to view some sort of map so I could anticipate running out of <>
b) the sketch is about 1500 bytes bigger than under IDE 21
I'll persist with 1.0 for now!
thanks for the encouragement

As I recall, this is mostly due to the changes in Serial. You said you moved your strings with F(), were they in PROGMEM before? That could also account for the increase if they were not.
nope
just ordinary boring strings before!
Yeah actually after thinking about it for a minute, what I said doesn't really make sense. Whether you store the strings in PROGMEM or not won't change the size of the sketch. They're going into flash one way or another... 
The size increase is from the changes to Serial.
but there is a 3 byte hit per string apparently (I seem to recall something like that in a thread nearby)
update:
ok I lied - no overhead at all!
Serial.println( "Whatever" );
...versus...
Serial.println( F( "Whatever" ) );
If you believe there is a per-string overhead in the latter, please let me know. Mikal and I spent a few hours ensuring the F-macro is as efficient as possible. If there is a per-string overhead then we made a mistake that should be corrected.
that's the trouble with rumours
facts do get in the way!
just did a quick test
hurriedly backtracks and withdraws statement
removed F( ) from several strings
no difference in size at all!
so well done chaps!

Excellent.
so well done chaps!
Thank you. And thank you for the follow-up.

But that isn't comparing non-PROGMEM to PROGMEM, it is showing that the streaming library has a slight overhead.
aha that's where I saw it!
