release: 0.29.0

[davidhewitt]

Closes #6010

We're getting close to shipping! There are just a few items remaining in #6010, however I expect we can get those all merged up to have this ready to go early next week.

[davidhewitt]

Just waiting for #5930 and #6124 then will rebase and prep CHANGELOG.

[davidhewitt]

I have rebased and updated the CHANGELOG, and set a release date for today; I'd like to put live this evening.
