  * Fixed pagination unexpected counts for `rlistings`' pagination by removing the manual subsetting workaround and fixing [`insightsengineering/rlistings#155`](https://github.com/insightsengineering/rlistings/issues/155).
  * Improved relevant information feedback during pagination.
  * Removed the possibility to set `min_siblings > 0` when dealing with listings. This allows smooth pagination when having only 2 lines.
+ * Added error catch for `\r` recursive special character.
 
 ## formatters 0.5.5
  * Applied `styler` and resolved package lint. Changed default indentation from 4 spaces to 2.
