 - New `glossa_article()` for articles of [Glossa: a journal of general linguistics](https://www.glossa-journal.org/) (thanks, @stefanocoretta, #361).
 
+- New `wellcomeor_article()` for Wellcome Open Research articles

 ## MAJOR CHANGES
 
 - Since **rticles** 0.15, per requirement with R Journal, `rjournal_article()` uses `knitr::purl()` to produce a R file with the code from the Rmd file. Last version eagerly overwrites any existing R file with the same name as the purled file. From now on, if a `.R` already exists with the name of the output, it won't be overwritten anymore, and not purled file will be outputted. This prevent issue with users maintaining themselves their own R file to accompany the article. A warning is issued to remind of deleting the existing R file is one want to use the purled R file (thanks, @Enchufa2, #433).
