The Kodi team has just released version 17.4 RC1 of their great app. They have already been underway on v18, their next big release, but are also working on 17.4 to address bugs that can’t wait for v18 to be completed. This is a release candidate, so it’s not fully vetted for issues just yet, but if you’ve had any crashing issues, you might want to give v17.4 RC1 a try. The easiest way to install it on the Amazon Fire TV, Fire TV Stick, or Fire TV Edition televisions is by using my Downloader app and entering bit.ly/kodi174rc into the URL field on the home screen. Minor updates like this new one never add any new features and are only released to improve the stability of the last major release, which was v17.
