3.2.2
Before the version 3.2.2 was released the following fixes were tested:

- #479: the CDMA/OFDMA tabs have been put back to the top
- #480: elevation angle is calculated and is now passed on to the method.
- #482: implementation of a warning to block users from using batch operation with OFDMA/CDMA module
- #483: the average but rate loss for the ref cell does not give NaN% anymore
- #487: in the CR module, it is now indicated that a negative value gives a loss for the Hidden Node Margin.
3.2.2 Beta 3
- #481 Bug 5: translation function not returning same value as for manual (issue created in beta version, not from official)
- #486 Enhancement 1: Harmonization of angle convention between CDMA/OFDMA and traditional module.

3.2.1
Before the version 3.2.1 was released the following fixes were tested:
Please note that the errors reported in 3.2.0 (email from 6 May 2010 on SEAMCAT reflector) have been corrected and the fixes are available in the 3.2.1 official version.
List of tickets and their corrections:
- Ticket #418: In traditional victim tabs, the shaded (x,y) fields in the Wt to Vr path tab are still active. This is corrected so that any shaded values are disabled, so that the positioning of the Vr with respect to the Wt is properly calculated.
- Ticket #419: In CDMA/OFDMA, the Dyn. (Wtx à reference cell BS) feature uses the Vr as its reference.This is corrected for both UL and DL so that the reference point is the Wt as indicated to the user.
- Ticket #420: In CDMA/OFDMA, the path distance factor is multiplied by the shaded simulation radius.This is corrected for both UL and DL so that the “Path distance factor” is changed to a “Path distance” and the simulation radius is still shaded and not used in the calculation. The distance between the Vr and the reference cell is the “Path distance”.
- Ticket #421: The antenna radiation pattern of the Vr (traditional system) not read when OFDMA/CDMA is interferer. Note that OFDMA/CDMA versus OFDMA/CDMA is not affected by this error. This is corrected. The antenna radiation pattern at the Vr is now taken into account in azimuth and elevation.
3.2.0
SEAMCAT-3 was upgraded to 3.2.0 version (11 March 2010) with the following features:
- OFDMA is now implemented in SEAMCAT using 3GPP LTE standard
- Overloading feature has been implemented
- CDMA snapshot vectors have been added to provided increased visibility to what SEAMCAT does
- Multiple generate of interferer graphical interface has been changed
- Enhancement to the ICE display
