There are two relevant rules:

From the FAQ: reposts are considered dupes if the story has had significant attention in the last year or so - https://news.ycombinator.com/newsfaq.html

From the Show HN guidelines: feature upgrades are generally not sufficient for a new Show HN - https://news.ycombinator.com/showhn.html

Of course there's some grey area here (what counts as an incremental upgrade) but I think 6 months is too soon for this post. Sorry to disappoint, but users email us to complain about these things.

Oh and none of this is meant to imply that you aren't doing great work!
