@ -41,6 +41,8 @@ Bugfix
* Fix overly strict bounds check in ssl_parse_certificate_request()
which could lead to valid CertificateRequest messages being rejected.
Fixes #1954.

and pk_decrypt example programs. Reported by Brace Stout. Fixes #1128.
Changes
* Copy headers preserving timestamps when doing a "make install".
