0.10.7 Public Beta Launch

This is the first stable (beta) release of EmuLinker-K, which is an improved version of EmulinkerSF, rewritten in Kotlin.

This release is intended for server admins who are already familiar with running EmuLinker servers. If you are brand new to hosting a server, you might want to skip this release. I will write more detailed instructions on setting up a server after we get some initial feedback.

Launching the server is almost identical to ESF, and it's compatible with your existing ESF config files. There are two important differences from ESF however:

1. A minimum Java version of 17 is required.
2. Your config files (emulinker.cfg and language.properties) need to be saved in UTF-8 format. If the file only contains English words, this probably doesn't matter.

There are a few new features in this build, but with this release I am more interested in getting feedback about core functionality. One difference you may notice is that the /lagstat command is overhauled and more accurately tracks lag caused by players. Currently this doesn't count lag spikes, it counts individual lagged frames (classified into "big" and "small" amounts of lag for the frame).

Feedback

Feel free to file bugs and feature requests on this repository in the Issues tab, or find our channel in the Kaillera Reborn discord:
