+# Changelog
+0.0.5 Fixed some errors when YT-Component gets destroyed and re-initialized, the problem was that YT replaced my div with an iframe and then on the component-destroy Svelte searches for an inexistent div ¯\_(ツ)_/¯ , an other problem was that the YouTubeIframeAPIReady only get called once when the first YT-Component is used, so when we recreate a Player the 'new YT.Player' function got never called
+0.0.4 Update svelte version
+0.0.2 Changed descripton
+0.0.1 Init
