# 3.20 - Article flags

18 March 2022

\- Custom fields and flags:  
\- custom fields are now displayable in articles lists  
\- select fields (both standard and custom) can now trigger flags on article lists and article pages  
These two features are very useful to identify specific workflows / critical articles

\- Mail history: users may now mask automatic mails in mail history.  
We realised mail history could get very crowded when several co-authors/editors are involved in an article.  
Masking automatic mails to show only "human" messages helps editors to identify important messages in the article history.

\- Referee invitations:  
\- when inviting a referee, a warning is displayed to the editor if the referee is currently working on another paper  
\- referee activity page: information is now more relevant
