Logically re-apply64c70a8c4c("doc: point out that nixos-21.05 has gnuradio 3.9"), because it was lost in the conversion from docbook to markdown, in commit32c2dd304d("docs: nixos release notes to CommonMark (2105)"). (Apparently we have both .md and .xml release notes now, and CI fails unless they have the same content (after .md processing), so update the .xml file to match...)
This directory is temporarily needed while we transition the manual to CommonMark. It stores the output of the ../md-to-db.sh script that converts CommonMark files back to DocBook.
We are choosing to convert the Markdown to DocBook at authoring time instead of manual building time, because we do not want the pandoc toolchain to become part of the NixOS closure.
Do not edit the DocBook files inside this directory or its subdirectories. Instead, edit the corresponding .md file in the normal manual directories, and run ../md-to-db.sh to update the file here.
