Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

In the Org Element API article describes that all elements share :begin
and :end:
https://orgmode.org/worg/dev/org-element-api.html#fnr.1

I don’t know where that changed, but I found that nowadays I have to use
`org-element-contents-begin' and `org-element-contents-begin' to get
the beginning and end of an element.

(this had broken the new article listing on my website for quite a while
until I now went to find the problem)

Best wishes,
Arne

Yes.

Why? What's wrong with `org-element-begin' and `org-element-end'?

I didn’t know that I could also use these ☺

What’s wrong is only that I had to fix showing the first paragraph of
articles on my website with this change:¹

But https://orgmode.org/worg/dev/org-element-api.html#fnr.1 claims that
it should still be working.

I do not see anything mentioning plist on that page. That WORG page
suggests using org-element-property.

Using plist-get is abusing implementation details that have been
changed. See https://orgmode.org/Changes.html#org92f24b2

Not a bug.
Canceled.
