My news md does not show up in my pkgdown site

Question

I have a R package called relper, recently I did some updating in my news file, here a sample:

# relper 3 (Calculations all the way)

To improve data analysis, I added functions that compute metrics and other calculations.

## 3.6.8

**Improvements:**

-   Parameter `prefix` to the function `dttm_vars`
-   Use of `format_num` to breaks labels, with `...` in the function `plt_scale_y_mirror`

## 3.5.0

**Addition:**

-   Function `stat_missing_values`.

In RStudio when I do a preview it shows ups perfectly:

But when I build the news (pkgdown::build_news()) or push to my repo the site look like this:

I'm not sure what caused it, because I just formatted some of the text.

Answer 1

So a NEWS.md file just accepts sections broken up into versions using level one (#) or level two headings (##) that (partially) match one of the following forms (ignoring case):

{package name} 1.3.0

{package name} v1.3.0

Version 1.3.0

Changes in 1.3.0

Changes in v1.3.0
