 mbed TLS ChangeLog (Sorted per branch, date)
 
-= mbed TLS 2.x.x branch released xxxx-xx-xx
+= mbed TLS x.x.x branch released xxxx-xx-xx
+
+Features
+   * Add the Any Policy certificate policy oid, as defined in
+     rfc 5280 section 4.2.1.4.
+   * It is now possible to use NIST key wrap mode via the mbedtls_cipher API.
+     Contributed by Jack Lloyd and Fortanix Inc.
+
+Bugfix
+   * Fix private key DER output in the key_app_writer example. File contents
+     were shifted by one byte, creating an invalid ASN.1 tag. Fixed by
+     Christian Walther in #2239.
+   * Fix potential memory leak in X.509 self test. Found and fixed by
+     Junhwan Park, #2106.
+   * Reduce stack usage of hkdf tests. Fixes #2195.
+   * Fix 1-byte buffer overflow in mbedtls_mpi_write_string() when
+     used with negative inputs. Found by Guido Vranken in #2404.
+   * Fix bugs in the AEAD test suite which would be exposed by ciphers which
+     either used both encrypt and decrypt key schedules, or which perform padding.
+     GCM and CCM were not affected. Fixed by Jack Lloyd.
+
+Changes
+   * Server's RSA certificate in certs.c was SHA-1 signed. In the default
+     mbedTLS configuration only SHA-2 signed certificates are accepted.
+     This certificate is used in the demo server programs, which lead the
+     client programs to fail at the peer's certificate verification
+     due to an unacceptable hash signature. The certificate has been
+     updated to one that is SHA-256 signed. Fix contributed by
+     Illya Gerasymchuk.
+   * Return from various debugging routines immediately if the
+     provided SSL context is unset.
+   * Remove dead code from bignum.c in the default configuration.
+     Found by Coverity, reported and fixed by Peter Kolbus (Garmin). Fixes #2309.
+   * Add test for minimal value of MBEDTLS_MPI_WINDOW_SIZE to all.sh.
+     Contributed by Peter Kolbus (Garmin).
+
+= mbed TLS 2.17.0 branch released 2019-03-19
+
+Features
+   * Add a new X.509 API call `mbedtls_x509_parse_der_nocopy()`
+     which allows copy-less parsing of DER encoded X.509 CRTs,
+     at the cost of additional lifetime constraints on the input
+     buffer, but at the benefit of reduced RAM consumption.
+   * Add a new function mbedtls_asn1_write_named_bitstring() to write ASN.1
+     named bitstring in DER as required by RFC 5280 Appendix B.
+   * Add MBEDTLS_REMOVE_3DES_CIPHERSUITES to allow removing 3DES ciphersuites
+     from the default list (enabled by default). See
+     https://sweet32.info/SWEET32_CCS16.pdf.
+
+API Changes
+   * Add a new X.509 API call `mbedtls_x509_parse_der_nocopy()`.
+     See the Features section for more information.
+   * Allow to opt in to the removal the API mbedtls_ssl_get_peer_cert()
+     for the benefit of saving RAM, by disabling the new compile-time
+     option MBEDTLS_SSL_KEEP_PEER_CERTIFICATE (enabled by default for
+     API stability). Disabling this option makes mbedtls_ssl_get_peer_cert()
+     always return NULL, and removes the peer_cert field from the
+     mbedtls_ssl_session structure which otherwise stores the peer's
+     certificate.
+
+Security
+   * Make mbedtls_ecdh_get_params return an error if the second key
+     belongs to a different group from the first. Before, if an application
+     passed keys that belonged to different group, the first key's data was
+     interpreted according to the second group, which could lead to either
+     an error or a meaningless output from mbedtls_ecdh_get_params. In the
+     latter case, this could expose at most 5 bits of the private key.
 
 Bugfix
    * Fix a compilation issue with mbedtls_ecp_restart_ctx not being defined

      in X.509 module. Fixes #2212.
    * Reduce stack usage of `mpi_write_hlp()` by eliminating recursion.
      Fixes #2190.
+   * Fix false failure in all.sh when backup files exist in include/mbedtls
+     (e.g. config.h.bak). Fixed by Peter Kolbus (Garmin) #2407.
+   * Ensure that unused bits are zero when writing ASN.1 bitstrings when using
+     mbedtls_asn1_write_bitstring().
+   * Fix issue when writing the named bitstrings in KeyUsage and NsCertType
+     extensions in CSRs and CRTs that caused these bitstrings to not be encoded
+     correctly as trailing zeroes were not accounted for as unused bits in the
+     leading content octet. Fixes #1610.
 
 Changes
+   * Reduce RAM consumption during session renegotiation by not storing
+     the peer CRT chain and session ticket twice.
    * Include configuration file in all header files that use configuration,
      instead of relying on other header files that they include.

      by Aurelien Jarno and submitted by Jeffrey Martin.
+   * Reduce the complexity of the timing tests. They were assuming more than the
+     underlying OS actually guarantees.
+   * Fix configuration queries in ssl-opt.h. #2030
+   * Ensure that ssl-opt.h can be run in OS X. #2029
+   * Re-enable certain interoperability tests in ssl-opt.sh which had previously
+     been disabled for lack of a sufficiently recent version of GnuTLS on the CI.
+   * Ciphersuites based on 3DES now have the lowest priority by default when
+     they are enabled.

-Mbed TLS includes an elaborate test suite in `tests/` that initially requires Perl to generate the tests files (e.g. `test\_suite\_mpi.c`). These files are generated from a `function file` (e.g. `suites/test\_suite\_mpi.function`) and a `data file` (e.g. `suites/test\_suite\_mpi.data`). The `function file` contains the test functions. The `data file` contains the test cases, specified as parameters that will be passed to the test function.

-# Purpose:
-# - To test and prove that a new commit in  the mbed TLS repository builds
-# and integrates with mbed-os properly.
-#           AND
-# - To test and prove that the current development head of mbed TLS builds
-# and integrates with the current mbed-os master branch.
-#
-# The script fetches all the prerequisites and builds the mbed TLS 'tls-client'
-# example. This script is triggered by every commit and once each night and the
-# exact behaviour depends on how it was triggered:
-# - If it is a nightly build then it builds the mbed TLS development head with
-#   mbed-os master.
-# - If it was triggered by the commit, then it builds the example with mbed TLS
-#   at that commit and mbed-os at the commit pointed by mbed-os.lib in the
-#   example repository.
