As MC 1.21.2 is approaching, this is the final update for 4.x branch. From now on, only 5.x versions will be released, which will no longer have unlimited nametag mode and bossbar for 1.8 servers. This was originally planned to come with MC 1.22 rather than 1.21.2, however, Mojang has decided to rework entity packets in 1.21.2 and I don't see the point in adding support for it just to remove the whole feature soon after. In case you missed it, here is the original (now updated) announcement: https://gist.github.com/NEZNAMY/f4cabf2fd9251a836b5eb877720dee5c
