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. Anything in between two releases was an intermediate version on the way to the next release.
IMPORTANT: Firmware versions 4.9 and later only support the following models:
- ST-IPM-6350
- VT-mIPM-245-D
- VT-mIPM-135-D
- VT-IPM2M-113-D
- VT-IPM2M-213-D
