XXL Packets - Packet Size Limit Extension
Attention: this mod is a fork of the original XL Packets with extended capabilities. The main goal is to eliminate the limitation of transmitted data packet size up to the maximum value supported by Java.
This solution fixes the known issue MC-185901 by increasing the maximum packet size from 2 megabytes to 2.14 gigabytes (2147483647 bytes). Thanks to this, servers with voluminous datapacks, complex data packets and other resources will no longer disconnect clients due to exceeding the limit.

For proper operation, the mod must be installed on the client side for all connecting players. This ensures compatibility and stable connection even when transmitting large amounts of data.
