I'm preparing to upgrade from TestCenter 4.80 to 4.98 but i'd like to see some release notes to see what's changed. The links on the download page lead me to
https://support.spirent.com/SpirentCSC/SC_KnowledgeView?Id=DOC10920 for the new features overview and
https://support.spirent.com/SpirentCSC/SC_KnowledgeView?Id=DOC10921 for release notes, but both links seem to be dead. Is there any other way to find or access the release notes?
