Upgrade Version 3.0.19. -> 3.0.22 needed??

[uj2.hahn at posteo.de]

Hi, FR-team!
*
*A while ago I installed FR 3.0.19 on Ubuntu 19.04.(ntlm_auth)
The school which is using this implementation for WLAN access has a very 
basic use model. They need
authentification functionality only.

Question is: Is there an urgent need (e.g. security, new hot 
functionality,...) to upgrade to 3.0.22?
Or do you think 3.0.19 is still good enough?

Thanks
Uwe
