難読化マップ（英：Obfuscation map）は、古い（元の）名称から新しい（難読化された）名称に変更されたクラスやクラスメンバの対応を表すProguardマッピングである[1]。これらは、19w36a以降にリリースされたスナップショットごとにclient.jsonへ出力されており、1.14.4のclient.jsonも、19w36aのリリース後に難読化マップを含めた更新が行われた[2]。
用途
The obfuscation maps can be used to remap obfuscated stack traces (as in crash reports) to readable stack traces.[3]
Dinnerbone and Adrian Östergård have suggested that the obfuscation maps may make modding easier.[4][5] Searge has implied that the obfuscation maps can replace certain third-party programs such as the Mod Coder Pack.[6]
