  This is the first version of the editorial foreword to the Perspective review
"Research Landscape of Altermagnetism" by L. \v{S}mejkal, et al, published in
Phys. Rev. X 12, 040501 (2022). Due to various editorial constraints the
publish version (DOI:10.1103/PhysRevX.12.040002) deviates substantially from
the initial text. This posting intends to make this original version available
for perusal of potential readers.
