My take is that given the other remaining issues with Tk-Cocoa and my 
own available time, updating deprecated methods is low priority. In 
response to another suggestion on this thread, I also am reluctant to 
load up Tk with a lot of OS-version-dependent API calls: the baseline 
supported version of Tk-Cocoa is 10.5 and that's where it should stay 
absent some huge reason to move it. (The shift to 64-bit and the 
significant changes in Objective-C with 10.5 merited such a baseline shift.)

One deprecated method that I haven't figured out how to address yet is 
garbage collection: Apple seems to be aggressively deprecating it in 
favor of automatic reference counting (ARC), and I haven't delved into 
the implications of this for Tk. It may not be necessary to worry about 
at all because Daniel Steffen designed Tk-Cocoa to support both GC and 
standard memory management, but it's something I will have to look at at 
some point.

If someone wants to submit a patch or two to address deprecated calls 
and they can be applied without breaking the 10.5 baseline of 
support--i.e., they don't require wrapping in an #ifdef to specify a 
later version of OS X--then I would be happy to review and include those.
