Hey I play on 1.14.4 and I do not wish to update my server, can you make a 1.14 version if it is easy? If it is, I would be very grateful although I do understand if you do not want to.

Why are you not updating to 1.15? 1.14 is not supported and won't be, no matter how many people ask for it.

Exactly. 1.15 is just 1.14 with bees and bugfixes. Almost nobody uses a 1.14 client anymore anyways so upgrading should be fine.

You may compile the 1,14,4 branch of lithium, but it is no longer supported. 1.15 is better in nearly every way, however, so you may want to switch.

Minecraft 1.14 is not supported any longer.
