This plugin should work with any Minecraft version that SilkSpawners itself supports, if not, please let me know.

Version 3.0.0

• Updates API to be SilkSpawners v6+ compatible. REQUIRES SILKSPAWNERS V6
• Updates bStats
• Updates bundled MongoDB dependency
• Various smaller code improvements

I've decided to open source the plugin - that means you can compile your own version directly from my GitHub. This is attended by a price increase, too, since the plugin is now basically free. The €15 are meant as an appreciation towards spending my free time since 8(!) years for developing and supporting SilkSpawners and Minecraft.
