libevent outdated for 5 month

[Konstantin Shalygin via arch-general <arch-general@xxxxxxxxxxxxx>]

Hello.

I found that libevent 
<https://www.archlinux.org/packages/core/x86_64/libevent/> is outdated 
from 2017-01-28.
The new stable is available 
https://raw.githubusercontent.com/libevent/libevent/release-2.1.8-stable/ChangeLog
Any reason this is not updated? I checked todo lists and bug-reports - 
found nothing.
