 ### Changes between 3.4 and 3.5 [xx XXX xxxx]
 
+* All the BIO_meth_get_*() functions allowing reuse of the internal OpenSSL
+  BIO method implementations were deprecated. The reuse is unsafe due to
+  dependency on the code of the internal methods not changing.

 * Support DEFAULT keyword and '-' prefix in SSL_CTX_set1_groups_list().
   SSL_CTX_set1_groups_list() now supports the DEFAULT keyword which sets the
   available groups to the default selection. The '-' prefix allows the calling

+It is not safe to use C<BIO_meth_get_> functions to reuse the B<BIO>
