  3. Re: “Note about updated package for 1.8.4”

    Anyone who gets these updates via RSS won’t see this edited version of the announcement, since it was added after the RSS feed was polled/sent. I’d suggest writing a new blog post/announcement when there’s something to add or the information has changed.

  4. невозможно загрузить файлы обновления, проверьте, пожалуйста
    i can not download the update files, please check

  5. I don’t know whats wrong with my installation. I tried to use the update package and the complete package (override existing files). Both Upgrades lead me to an update “Upgrade my existing copy of MyBB to 1.8.3”

    After the upgrade I’m still on 1.8.3
