HR: 8.2.5.01-132-g25495ea-alpha

I know HR is not meant to optimize lower level characters, but generally it does pretty well at it anyway. A recent update to the Feral module, though, has made it inoperable without the BfA neck. The addon throws errors upon entering combat until the game throttles it.

That is the update prior to the one with the above commit. If you're using Curse, they might just have been slow to package the update.

Edit: https://www.curseforge.com/wow/addons/herorotation/files/2870562 will have the latest update. It looks like the Twitch app might just be a bit slow at the moment.

This should be fixed by commit 0ea4c60
