IO Build after doc updates

IO build after doc update

Build io-upload-iframe for 2531308.

Generate build for fix 2530931.

Build commit for fix 2531041.

Reinstate code changes This is a revert-revert. Code changes made on the 3.4.0+ branch were reverted on the branch, then this revert commit merged into master (since all commits on 3.4.0+ should be documentation, a blanket merge should be safe), which then reverted the code changes where they were appropriate. Short form: this commit allows blanket merges from 3.4.0+ onto master again at the expense of some git log history confusion for IO. This reverts commit 3327eba7caef16e3d5b0496f979b07c9998e70b7.
