Hi,
Paragraphs are no longer blocks, they say. So tinymist made me change
#show par: set block(spacing: 0.65em)
to
#set par(spacing: 0.65em)
Fine by me.
What’s the place of the paragraph in the scheme of things now? An element?
Otherwise, the paragraph behaves very much as before. Why? An explanation of the new basic text layout is welcome 
There have been several changes. As I understand, initially paragraphs were not elements, but were treated as blocks in some respects. But setting par spacing with #show par: set block(spacing: ...) had several problems, so the par(spacing: ...) property was introduced in Typst 0.12. The problems this solves are described in the PR that made this change.
The next release (Typst 0.13) introduces semantic paragraphs. Now a par is actually a real element. I think the main motivation was to have a distinction between paragraphs and other pieces of text. But it also brings the benefit that we can process paragraphs in show rules like other elements. See this PR for details.
With the new par elements, many things that were difficult or impossible are now easy:
#show par: it => {
counter("par").step()
place(left, dx: -3em, context counter("par").display())
if "Lorem" in it.body.text {
set text(red)
it
} else {
it
}
}
Some paragraph.
#lorem(30)
Other paragraph.
