    => You can disable this menu in the settings under ""Look & Feel"".
• Added a way for plugins to add information to the game's server info bar (e.g. current song, ping, etc).
    => You can disable and reorder this information in the settings, if any plugin provides it.
• Switched the plugin download server to a self-hosted solution instead of GitHub, to circumvent API limits, country blocks and bad ISP routing.
    => Please see the ""Are plugins safe to use"" part of the XIVLauncher FAQ(goatcorp.github.io/faq) or reach out on Discord if you have concerns about security or want details on how this is set up and ran.
    => Changelogs in-game/the plugin installer should now also be more common, as the new service takes changelogs from the developer pull request descriptions.
• The ""Available Plugins"" list in the plugin installer now also shows installed plugins to make the spit less confusing. A new filter mode that filters installed plugins has been added.

If you note any issues or need help, please make sure to ask on our discord server.
Thanks and have fun with the new expansion!";

• Open the plugin installer, then click 'update plugins'. Updated plugins should update and then re-enable themselves.
   => Please keep in mind that not all of your plugins may already be updated for the new version.
   => If some plugins are displayed with a red cross in the 'Installed Plugins' tab, they may not yet be available.

While we tested the released plugins considerably with a smaller set of people and believe that they are stable, we cannot guarantee to you that you will not run into crashes.

Considering current queue times, this is why we recommend that for now, you only use a set of plugins that are most essential to you, so you can go on playing the game instead of waiting endlessly.";
