Changed

• Bumped Go version to 1.12.

Fixed

• /textures request no longer proxies request to Mojang in a case when there is no information about the skin, but there is a cape.
• #5: Return Redis connection to the pool after commands are executed

Removed

• hash field from /textures response because the game doesn't use it and calculates hash by getting the filename from the textures link instead.
• hash field from POST /api/skins endpoint.
