[DRE-maint] Bug#712954: 1.4.3

[Axel Wagner]

retitle 712954 jekyll: A newer version is available (1.4.3)
thanks

It has been quite a while since jekyll has been updated. Some releases
also contain security fixes. Since I would like to use jekyll in
$dayjob, I am quite interested in a good health of this package. So if
the delay in uploading new versions is for a lack of manpower, I would
gladly commit some time to this.

Best,

Merovius
