update changelog for 2.3.9

Solaris 11 recently introduced a builtin arc4random in libc which fails the tests in "make check". Found USE_BUILTIN_ARC4RANDOM, but could not get it to work. Apparently, there is a typo in the configure logic rendering USE_BUILTIN_ARC4RANDOM ineffective.

 LibreSSL Portable Release Notes:
 
+2.3.9 - Reliability improvements
+
+	* Avoid continual processing of an unlimited number of TLS records,
+	  which can cause a denial-of-service condition.
+
+2.3.8 - Security and reliability fixes
+
+	* Avoid unbounded memory growth in libssl, which can be triggered by a
+	  TLS client repeatedly renegotiating and sending OCSP Status Request
+	  TLS extensions.
+
+	* Avoid falling back to a weak digest for (EC)DH when using SNI with
+	  libssl.
+
+2.3.7 - OCSP fixes
+
+	* Fix several issues in the OCSP code that could result in the
+	  incorrect generation and parsing of OCSP requests. This remediates a
+	  lack of error checking on time parsing in these functions, and
+	  ensures that only GENERALIZEDTIME formats are accepted for OCSP, as
+	  per RFC 6960.
+
+	  Issues reported, and fixes provided by  Kazuki Yamaguchi <k@rhe.jp>
+	  and Kinichiro Inoguchi <kinichiro.inoguchi@gmail.com>
+
+2.3.6 - Security fix
+
+	* Correct a problem that prevents the DSA signing algorithm from
+	  running in constant time even if the flag BN_FLG_CONSTTIME is set.
+	  This issue was reported by Cesar Pereida (Aalto University), Billy
+	  Brumley (Tampere University of Technology), and Yuval Yarom (The
+	  University of Adelaide and NICTA). The fix was developed by Cesar
+	  Pereida. See OpenBSD 5.9 errata 11, June 6, 2016
+
+2.3.5 - Reliability fix
+
+	* Fixed an error in libcrypto when parsing some ASN.1 elements > 16k.
+
 2.3.4 - Security Update
 
 	* Fix multiple vulnerabilities in libcrypto relating to ASN.1 and encoding.
