Version 0.0.7 is required for 1.16 release candidates and maybe some other snapshots.
Version 0.0.6 works in all 1.15 snapshots and in pre releases 1 and 2.
This mod makes it so that nearby experience orbs merge together this can be installed purely server-side only and requires only the fabric mod loader to function.
Prior to version 0.0.6 all experience orbs would merge every 2 seconds. However now each experience orb can merge with another every 1/4 of a second.
