 mbed TLS ChangeLog (Sorted per branch, date)
 
+= mbed TLS 2.3.0 branch released 2016-06-28
+
+Security
+   * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt
+     required by PKCS1 v2.2
+   * Fix potential integer overflow to buffer overflow in
+     mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt
+     (not triggerable remotely in (D)TLS).
+   * Fix a potential integer underflow to buffer overread in 
+     mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in
+     SSL/TLS.
+
+Features
+   * Support for platform abstraction of the standard C library time()
+     function.
+
+Bugfix
+   * Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three
+     arguments where the same (in-place doubling). Found and fixed by Janos
+     Follath. #309
+   * Fix potential build failures related to the 'apidoc' target, introduced
+     in the previous patch release. Found by Robert Scheck. #390 #391
+   * Fix issue in Makefile that prevented building using armar. #386
+   * Fix memory leak that occured only when ECJPAKE was enabled and ECDHE and
+     ECDSA was disabled in config.h . The leak didn't occur by default.
+   * Fix an issue that caused valid certificates to be rejected whenever an
+     expired or not yet valid certificate was parsed before a valid certificate
+     in the trusted certificate list.
+   * Fix bug in mbedtls_x509_crt_parse that caused trailing extra data in the 
+     buffer after DER certificates to be included in the raw representation.
+   * Fix issue that caused a hang when generating RSA keys of odd bitlength
+   * Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made null pointer
+     dereference possible.
+   * Fix issue that caused a crash if invalid curves were passed to
+     mbedtls_ssl_conf_curves. #373
+   * Fix issue in ssl_fork_server which was preventing it from functioning. #429
+   * Fix memory leaks in test framework
+   * Fix test in ssl-opt.sh that does not run properly with valgrind
+   * Fix unchecked calls to mmbedtls_md_setup(). Fix by Brian Murray. #502
+
+Changes
+   * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5,
+     don't use the optimized assembly for bignum multiplication. This removes
+     the need to pass -fomit-frame-pointer to avoid a build error with -O0.
+   * Disabled SSLv3 in the default configuration.
+   * Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey
+     Skalozub).
+   * Fix non-compliance server extension handling. Extensions for SSLv3 are now
+     ignored, as required by RFC6101.
+
 = mbed TLS 2.2.1 released 2016-01-05
 
 Security
    * Fix potential double free when mbedtls_asn1_store_named_data() fails to
      allocate memory. Only used for certificate generation, not triggerable
      remotely in SSL/TLS. Found by Rafał Przywara. #367
-   * Disable MD5 handshake signatures in TLS 1.2 by default
+   * Disable MD5 handshake signatures in TLS 1.2 by default to prevent the
+     SLOTH attack on TLS 1.2 server authentication (other attacks from the
+     SLOTH paper do not apply to any version of mbed TLS or PolarSSL).
+     https://www.mitls.org/pages/attacks/SLOTH
 
 Bugfix
    * Fix over-restrictive length limit in GCM. Found by Andreas-N. #362

- *                 network congestion by causing more retransmissions.

+ *                 expected round-trip time to your peer, plus whatever time
+ *                 it takes for the peer to process the message. For example,
+ *                 if your RTT is about 600ms and you peer needs up to 1s to
+ *                 do the cryptographic operations in the handshake, then you
+ *                 should set 'min' slightly above 1600. Lower values of 'min'

+Commands
+    set <symbol> [<value>]  - Uncomments or adds a #define for the <symbol> to
+                              the configuration file, and optionally making it
+                              of <value>.
+                              If the symbol isn't present in the file an error
+                              is returned.
+    unset <symbol>          - Comments out the #define for the given symbol if
+                              present in the configuration file.
+    get <symbol>            - Finds the #define for the given symbol, returning
+                              an exitcode of 0 if the symbol is found, and -1 if
+                              not. The value of the symbol is output if one is
+                              specified in the configuration file.
+    full                    - Uncomments all #define's in the configuration file
+                              excluding some reserved symbols, until the
+                              'Module configuration options' section
+    realfull                - Uncomments all #define's with no exclusions
+
+Options
+    -f | --file <filename>  - The file or file path for the configuration file
+                              to edit. When omitted, the following default is
+                              used:
+                                $config_file
+    -o | --force            - If the symbol isn't present in the configuration
+                              file when setting it's value, a #define is
+                              appended to the end of the file.

+#
+# The tests focus on functionality and do not consider performance.

+Any performance data generated by this example application are indicative only of the performance of the mbed TLS module on the platform it's executed on.
+
+Differences in the integration of mbed TLS into the platform, such as whether all available hardware accelerators have been used or not, can lead to significant differences in performance, and so results from the program are not intended to be used to meaningfully compare platforms.
+
+The figures may also slightly change from execution to execution due to variations in the timing functions.
