fix rstudio#1716: drop the compact-title option in YAML; the smalle…

…r spacing does not seem to worth our official support, and we will let users opt-in if they really prefers the spacing, at the price of providing their own LaTeX templates if they have multiple authors in a document

 rmarkdown 1.19
 ================================================================================
 
+- For the output format `pdf_document()`, we no longer adjust the vertical spacing of the title area. This means there will be a larger spacing above the document title in PDF. If you prefers the old (smaller) spacing, please download https://github.com/rstudio/rmarkdown/blob/f6961af/inst/rmd/latex/compact-title.tex and include it to the preamble via the `includes` option of `pdf_document`. However, please note that this means you won't be able to have multiple authors in the `author` field of the YAML frontmatter, unless you use a custom LaTeX template. With the default LaTeX template, you will run into the error in #1716. Besides, the `compact-title` option in YAML is no longer supported.
+
 - The `encoding` argument is no longer passed to the `intermediates_generator` of R Markdown output formats. The `intermediates_generator` function can only accept arguments `input_file` and `intermediates_dir` now (see `?rmarkdown::output_format`). This is a breaking change to developers. If you are an output format developer, you have to remove the `encoding` argument in your `intermediates_generator` if your output format uses this function.
 
 - The `encoding` argument is no longer passed to the `render` element of the site generator (see `?rmarkdown::render_site`).
