You can repost after a year or so (see https://news.ycombinator.com/newsfaq.html under reposts) but you just had a big Show HN about a month ago which is probably too recent. Feature updates by themselves are not typically enough for an early repost, that's mentioned in https://news.ycombinator.com/showhn.html

Hey, thanks for the info, I didn't know that there is a wait period. The version I posted back then was still very much in its alpha stage, compared to now. I would say it is a major difference, but I also get that HN doesn't want too many product updates posted
