Sorry for that. I noticed it myself yesterday but was too tired to fix 
it. I've just posted an update that adds #at:ifAbsentPut: as part of the 
at:[put:|ifAbsent:|ifPresent:] family of methods on SmalltalkImage.

Also, make sure you update from the TweakCore repository; I've posted a 
fix for CParser that has much larger potential of causing some headaches 
because it effectively turns off CParser completely (change from using 
#method:context:encoder to #method:context:).

There is not much you need to do. The one thing to check is whether any 
extension methods are still on SystemDictionary; those need to be 
transferred to SmalltalkImage. If you care about portability you might 
need to access them via SmalltalkImage current xxx if you don't just 
keep using Smalltalk xxx.

I don't recall if there were any extensions in Croquet or Cobalt but the 
three extensions from Tweak are harmless since they're not used (and 
I'll remove them when I get around to it).
