There aren't any valid reasons here to NOT update your server to a 1.9+ version. The most common "reasons" about why sticking with 1.8 are often either "The 1.9 PvP sucks!" or "Other servers do that too!" I mean even the author of this thread gave this response: First of all: Stop taking big servers as role models or reasons for your server. They are big because they are popular (obviously). Just because Hypixel, HiveMC or whatever other servers you mention has 1.8 as basic server version, doesn't mean it will work with your 1.8 Spigot server. First is the server most likely custom made, so that the devs can easily integrate new game modes, systems, etc. For example, does Hypixel have a custom save-system for the worlds (The SRF-system) which plugins like SlimeWorldManager add to Spigot. We should stop here to do something just because others do it, or else your server will be yet another "SkyBlock, Factions and Creative Server with Prison setup". You don't wanna know how many of those servers I saw so far.... There are multiple reasons for devs to use newer API versions and drop support for older ones. The most important one is, that the API got major (often breaking) changes which make backwards-compatibility nearly impossible without the usage of things like Reflection, which isn't an easy task for beginner-devs. 1.9 brought some major changes and 1.13 was a huge breakpoint for plugins using sound-, entity-, block- and item-names/ids, as those got huge changes then. If you are aware that 1.8 is 5 years old AND has limitations to 1.9, why trying to find arguments to convince us to still support it? Like I said at the beginning are there no valid reasons here to justify using and supporting an old version. People stick with it because others do that too and if we don't break this stupid behaviour, then we will still be here at 1.8 even when 1.20 would be out. Another thing I love to do is comparing updating Spigot with updating your PC or Smartphone. Imagine you have a nice Android or Windows version and you receive the notification that there's a new version, which fixes bugs, glitches and most importantly: security vulnerabilities. You get info from friends and other people that the update, however, changed some stuff at the UI, behaviour, etc. of the OS. Would you keep the old version and risk the security vulnerabilities, or would you update, fix those issues and adapt to the changes? If you stick with not updating your OS, then I wish the best of luck to not get any attacks on your PC or Smartphone and with receiving support for this outdated OS. A server can (and maybe should) be treated as an OS, meaning you should update it to fix all kinds of issues. Only god knows what for exploits 1.8 has that were fixed in later updates.
