[SciPy-Dev] Submitting patches, updates

[Vincent Davis]

About 1.5 weeks ago I posted an email at the end of an email tread
saying I have updated codata.py to the 2006 physical constants. It
might have been missed since it was at the end of a tread and I am
sure it is of low priority. But my question is what it the right way
to submit a patch our updates?
Should they be announced as an separate email?
Should I submit a diff?
I bring this up as I was waiting for the code to be updated before I
completed the update to the docs for this file.
