Previous wolfSSL versions required X.963 KDF support and AES keywrap functionality to be enabled in order to build CMS/PKCS#7 decode support. Recent changes to wolfSSL have allowed CMS/PKCS#7 decode support to be built without either of these requirements. Previously, if the user desired to have the HAVE_PKCS7 build option defined, then the HAVE_X963_KDF and HAVE_AES_KEYWRAP build options were also required. Now, the HAVE_X963_KDF and HAVE_AES_KEYWRAP build options are optional and wolfSSL can be built with HAVE_PKCS7 enabled and either or neither of these build options enabled.
