It's true I haven't been actively maintaining Whenever. In part it's because I'm not actively using it. I regularly
glance at the issues and get the sense that most stem from people's unfamiliarity with their environment and the differences between it and the one cron runa in. Sure, it would be great if Whenever could smooth these over, but that was really never its intention. The cron syntax is tricky and Whenever provides a better one.
Please do list the most pressing issues / bugs and I'll try to address them.
