Halium 13 and 14?

The "Get Halium Source" page contains list:

If the target device has Android 12.0 or LineageOS 19 support, it’s recommended to select halium-12.0:
repo init -u https://github.com/Halium/android -b halium-12.0 --depth=1
If the target device has Android 11.0 or LineageOS 18.1 support, it’s recommended to select halium-11.0:
repo init -u https://github.com/Halium/android -b halium-11.0 --depth=1
If the target device has Android 10.0 or LineageOS 17.1 support, it’s recommended to select halium-10.0:
repo init -u https://github.com/Halium/android -b halium-10.0 --depth=1
If the target device has Android 9.0 (Pie) or LineageOS 16.0 support, it’s recommended to select halium-9.0:
repo init -u https://github.com/Halium/android -b halium-9.0 --depth=1
...

Following pattern there are exist halium 13 and halium 14 if you look on branches on github repo. Shouldn't they be mentioned on the page too? I am not user just a curious reader so Idk if it is outdated info or if there any reason 13 and 14 not mentioned on the page ¯\_(ツ)_/¯
