OS5: isn't Samba 4.9.x end of life?


Just out of curiosity.

OS5 is said to be shipping with an updated version of Samba. The release notes read:

  • Updated Samba to version 4.9.5+dfsg-5+deb10u1

However, it appears here: https://wiki.samba.org/index.php/Samba_Release_Planning that Samba 4.9.x is discontinued since March 3rd, 2020 (with the latest version being 4.9.18).

Should we be worried about security?

Why is an older and discontinued version being used in OS5?

FYI, the current stable branch is 4.13.x.
