Insertion devices are key components for high brightness third and fourth generation synchrotron facilities, and even for compact light sources where new acceleration concepts are envisioned. Different technological developments carried out worldwide lead to improved undulator performance. In-vacuum permanent magnet undulators demonstrate to be quite useful and adequate devices for present storage ring and Free Electron Lasers (FELs). Pushing towards higher fields with shorter undulator period becomes possible in operating at cryogenic temperature with Nd2Fe14B or Pr2Fe14B magnets. The development of Cryogenic Permanent Magnet Undulators (CPMU) is reported, including the issues in terms of magnet choice, thermal handling, magnetic measurements, radiation properties. Prospects for pushing the CPMU performances are given, with variable gap undulator or a combination with superconducting coils.
