Content Matrix build 126.96.36.199 has been replaced with build 188.8.131.52 due to the following,
During the migration to SPO, an exception occurs "Exception: AddList - Error [Versioning must be enabled and the number of major versions must be between 1 and 50000.] in Updating list Information action" while updating the list information of Site Pages, Style Library, Wiki Page Library.
The reason for the error message is Microsoft has changed some version settings for the SPO.
The "No Versioning" option and Checkbox for "Keep the following number of major versions" is removed from SPO. So, it is mandatory to provide the limit for the major version number. By default this value is 500. For UI the range for value is 100-50K.
