History

Java Edition
1.15	Pre-release 1	Added `signs.png-atlas`, following the splitting of `textures-atlas`.
1.19.3	22w42a	As an optimization to resource pack loading, everything in the relevant directory is compiled into this atlas, rather than only those sprites which are used by the game.
1.19.3	22w46a	A customizable atlas json file has been added which can be used to control which graphics are added to this atlas.
1.19.4	Pre-release 3	The way in which sprites are arranged on atlases has been changed considerably, resulting in atlas dimensions being generally smaller.
1.19.4	Pre-release 3	This atlas can now be exported to the screenshots folder using F3+S.

Mipmapped versions

Minecraft also generates mipmapped versions of this atlas, for unknown reasons. They are not used by the game at all - only blocks placed in the world which use the json model system use mipmapped textures.^[5]
