Comment(by burcin):
I put a preliminary version of the new pynac package here:
http://sage.math.washington.edu/home/burcin/pynac/pynac-0.1.6.spkg
I haven't actually committed the version information to the pynac
repository yet. I plan to wait until this gets reviewed, and see if there
are any last minute changes needed.
The newly uploaded patches:
* attachment:trac_5777-11-hash_doctests.patch
* attachment:trac_5777-12-pickle_expression.patch
* attachment:trac_5777-13-pickle_sfunction.patch
* attachment:trac_5777-14-exp.patch
correspond to the changes in the new package.
The changes in pynac are:
* Fix error handling in Number_T::hash().
* Add support for archiving numeric and function objects.
* Fix comparison bug in mul.
* Fix gcc warnings about conversion of strings to char*.
* Change exp to not prints exponents of 1.
* Add power method to exp so that `(e^x)^y -> e^(x*y)`.
Note that this fixes #5944, which I consider a blocker.
