 ### To use it on 64bit Windows immediately
 
 Just download the all-in-one package (`LizGoban-*_win_*.zip`), unzip it, and double-click `LizGoban *.exe`. You do not need installation, configuration, additional downloads, and so on. Its file size is due to the built-in engine:
 
-* [KataGo 1.12.4](https://github.com/lightvector/KataGo/releases/tag/v1.12.4) (eigen, eigenavx2, opencl) + [15 block network](https://katagotraining.org/networks/) (g170e-b15c192-s1672 from [KataGo 1.4.5](https://github.com/lightvector/KataGo/releases/tag/v1.4.5))
+* [KataGo 1.13.0](https://github.com/lightvector/KataGo/releases/tag/v1.13.0) (eigen, eigenavx2, opencl) + [15 block network](https://katagotraining.org/networks/) (g170e-b15c192-s1672 from [KataGo 1.4.5](https://github.com/lightvector/KataGo/releases/tag/v1.4.5))
 
 You can switch KataGo versions (CPU, modern CPU, GPU) by [Preset] menu in LizGoban. The first run of the GPU version may take a long time (1 hour on a low-spec machine, for example) for its initial tuning.
