Now that the g729 patents have expired, how do we use g729 in Asterisk?
Will Digium be releasing a g729 codec for ‘free’ use or do we download the
‘free’ codec off the Internet now that we can use it without moral or legal restrictions?
You can uses:
I’m hoping Digium will do something so we can have an ‘out of the box’
experience rather than downloading code from a lesser known web site.
I understand your question and your point, but I use the g729 codec from the link that Carlos share, for almost 6 years from Asterisk 1.4 to v13
without a single problem.
So, sory but I don’t share your phrase “from a lesser know web site”.
About your question, I did not known that the patent has expired, so I
expect and answer just like you.

AFAIK g729 patent is expiring sometime in 2019-2020.
G.729 includes patents from several companies and is licensed by Sipro Lab Telecom. Sipro Lab Telecom is the authorized Intellectual Property Licensing Administrator for G.729 technology and patent pool.
As of January 1, 2017 the patent terms of most Licensed Patents under the G.729 Consortium have expired, the remaining unexpired patents are usable on a royalty-free basis. Thus, G.729 can be used free-of-charge.

A better source is from the consortium which has been upholding the patents:
Yes, this link is reference #7 on the wikipedia article 😉
For the record: the coded module from there can be built with the library bcg729, and I believe it should be perfectly legal to use now
(Unlike the Intel IPP, that will require a specific license due to copyright considerations).
However the author is not seem willing to submit that code for inclusion into Asterisk. So if anybody wants to write a G.729 codec using that library: feel free to do so.
