Some users don't like the collapse bars besides the comments that collapse the comment tree, especially on mobile, so now you can disable them in your preferences.
Previously we had issues with the pagination of the posts lists, and we temporarily bandaged it by removing the ability to go past page ten. This has been fixed and you can go back further in post lists now.
Our devs discovered that custom CSS styles could be exploited to create a security vulnerability, so we removed the custom CSS option out of an abundance of caution. This wasn't exploited. Only moderators were able to make custom styles.
More coming soon. Thank you to our devs!
