- Fix a bug where sending a post with an image on 4chan.org boards (nsfw) would result in this post not showing up in the thread. The reason is the user agent that was used. For some reason, using any existing user agent (the one of a real browser) would result in this behavior. Using completely made up user agent (like "KurobaEx v1.2.3.4)") works fine. This is apparently either a 4chan bug or was done intentionally.
