Here it is:
I’m not sure that I got every benefit of that. Most use for me - copy and paste
<div style="page-break-after: always;"></div>
to Typora editor (I use Discourse as a source of Markdown notes and short documents for DevOps).
With new update this is copied as formatted code, not as plain text. Typora used to handled such construction as html code (auto detected) and made a page brake during next conversion to PDF. Now my favorite editor thinks that it is pasted as code now (by default with ruby formatting). Finally I mean that now I cannot safely use Discourse as code source. The data comes to clipboard not as plain text. Maybe that was designed as lazy feature, but for perfectionists like me such updates break their usual lifestyle)
Anyway that’s my opinion, my case is very rare.
