电骡爱好者们最常用的eMule mods之一，“刀疤天使骡” - eMule ScarAngel Mod的新版v4.2由作者Stulle在eMule（电骡）官方论坛发布了。 它基于eMule v0.50a Xtreme 8.1制作。
除了继承了Xtreme的特性，天使骡更关注于功能的强大，例如：增加了多种积分系统，老板键（一键隐藏），系统后台服务运行（无界面），多 账号网页远程管理支持，TBH迷你骡（minimule），自动备份配置文件，增强的下载分类管理，稀有文件推送，更多高级功能设置等等。
关于此次更新，作者的说明：
Dear customers,
I am happy to bring you a new and improved version of ScarAngel. It seems our hard working developers were having too much fun on the last release. But don't fear, those days are over! No more fun within the realm of ScarAngel Industries Ltd. from hear on out!
This release will do a couple of things differently in order to avoid different threads changing the upload list. We hope this will improve stability for you, our dear customers. Additionally, we also added two minor GUI goodies. As usual, check the changelog for more.
Yours dearly, Stulle

based on eMule 0.50a Xtreme 8.1 compiled with vs2010 SP1
Changed: Pause UBT when moving down slots in upload [Stulle] - Stulle

Changed: Schedule clients for moving down [Stulle] - Stulle
Changed: Show ModID in systray dialog sidebar [Stulle] - Stulle
Changed: Display ratio activation in WebInterface [Stulle] - Stulle
Fixed: Potential NULL-pointer bugs in Upload Bandwidth Throttler [Stulle] - Stulle
Note: The schedule changes will delay removal of blocking or moving down clients so the action will
be done when going through the uploading sockets the next time to avoid exceptions due to
changes in the upload list done by another thread while going through the sockets.
