Don't spread false information.
0.5 was released near end of Nov/start of dec. The christmas update came a month after 0.5, which he didn't have to do and was more than within his rights to take a break. Work on 0.6 started only in mid Jan, so it's been only 3 months or so. BTW did i forget to mention he isn't dropping an update with merely 100 images and 1 or 2 one second looped animations, these updates are gigantic. 0.5 had 800 new renders and 60 new animations, 0.4 had 1200 renders and 93 animations. 0.6 will have similar numbers. These cannot be acheived because he makes more money, there is a lot of work that has to be done.
The 100$ patreons can cancel their pleadge if they want just as the other paterons can. They don't feel cheated, so they continue to support. Even if the next update is dropped in July 2019, they know it's worth it.
If all you want are regular, timely updates, check out Man of the House (Faerin). They drop an update every 2 weeks with whatever content the made in that period.
