The 1.2a adds the textures of the environment and the font of writing. I intend to make a B version that modifies the hearts and bar of food and adds the interfaces of the 1.11 and 1.12 and the effects of potions.
The light version is still topical! It also has its version 1 .2a which modifies the font and the hearts and bar of food. The light version 1.2b will lose its texture of the hearts.
Some correction on the font font will be waiting in the next versions.
