I have stopped developing ZirconEssentials now. v2.0.1 is still available for download but it will not be maintained and I will NOT be updating it to new Minecraft versions. Thank you guys for the support and I'm sorry for any inconvenience caused.
Guys, thanks so much for the support with this plugin, we are at 100 downloads. I never thought it would come this far.
You can find the source code of the plugin here
This plugin was my first big project that helped me get to where I am with coding now. I started using PogoStick29's plugin tutorials and I just expanded on it so it was basically another Essentials but customised to how I wanted it.
