Without going into the specifics (because I don't know them) E3D got into a bit of hot water with the name of their new Hermes extruder and determined that just renaming the extruder to Hemera would make life easier. Is there a way to change e3d-hermes to e3d-hemera and perhaps make the former synonymous with the latter?
Yes it is possible to rename tags, but it would indeed be better to create a synonym as the extruder has had the Hermes name for a while. This means the Hermes tag will be replaced by the Hemera tag after adding/confirming the tag in the question.
Has been done, there where only 2 questions.
