Sixnet® IPm® Firmware Revision History
Note: IPm firmware versions are of the form major.minor.buildnumber. A letter X will be appended in the case of unreleased experimental versions. Other letters may be added in the case of patches or other special versions. As such, releases which are not consecutive are to be expected.
