Blame

(V.3.7.0 Changes) (1.16.2/1.16.3/1.16.4/1.16.5 Minecraft)

Dispenser Behaviors:

Printing Dispenser Behaviors Registry Replacements is now turned off by default since I have not seen a single problem yet with mods modifying Dispenser Behaviors that was solved by logging them out. You can turn it on by editing config/blame-forge.properties file above the mods folder.

Structure Step:

Detects and prints out what structure is missing their entry in the Structure.STEP map. That map is used for determining what generation step the structure will generate in unless the structure overrode getStep() method.

Biome Source:

Detects if a dimension's biome source has a null entry in their possibleBiomes list which will cause a crash with /locate and other structure checks.
