It would appear that a total of four snapshots were released between December 15 and December 21, snapshot 20171220 being the last one available for OpenSuSE Tumbleweed. And they include a few interesting things, such as the massive KDE Application 17.12.0 software suite for KDE Plasma 5 users.
When the KDE Applications 17.12.0 packages arrived in the Tumbleweed repositories, they included a bug for the KMail email client that couldn't send out email over secure SMTP connections. However, the openSUSE Tumbleweed was quick to release a fix for this issue in the update channel.
