 mbed TLS ChangeLog (Sorted per branch, date)
 
-= mbed TLS 2.1.x released xxxx-xx-xx
+= mbed TLS 2.1.10 branch released 2017-xx-xx
 
 Security
+   * Fix buffer overflow in RSA-PSS verification when the hash is too
+     large for the key size. Found by Seth Terashima, Qualcomm Product
+     Security Initiative, Qualcomm Technologies Inc.
+   * Fix buffer overflow in RSA-PSS verification when the unmasked
+     data is all zeros.
    * Fix unsafe bounds check in ssl_parse_client_psk_identity() when adding
      64kB to the address of the SSL buffer wraps around.
 
-= mbed TLS 2.1.8 released 2017-06-21
+Bugfix
+   * Fix some invalid RSA-PSS signatures with keys of size 8N+1 that were
+     accepted. Generating these signatures required the private key.
+   * Fix ssl_parse_record_header() to silently discard invalid DTLS records
+     as recommended in RFC 6347 Section 4.1.2.7.
+   * Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
+     Found by projectgus and jethrogb, #836.
+   * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
+   * Parse signature algorithm extension when renegotiating. Previously,
+     renegotiated handshakes would only accept signatures using SHA-1
+     regardless of the peer's preferences, or fail if SHA-1 was disabled.
+   * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
+     dates on leap years with 100 and 400 intervals are handled correctly. Found
+     by Nicholas Wilson. #694
+
+= mbed TLS 2.1.9 branch released 2017-08-10
+
+Security
+   * Fix authentication bypass in SSL/TLS: when authmode is set to optional,
+     mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
+     X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
+     (default: 8) intermediates, even when it was not trusted. This could be
+     triggered remotely from either side. (With authmode set to 'required'
+     (the default), the handshake was correctly aborted).
+   * Reliably zeroize sensitive data after use in AES example applications
+     programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
+     Found by Laurent Simon.
+
+API Changes
+   * Certificate verification functions now set flags to -1 in case the full
+     chain was not verified due to an internal error (including in the verify
+     callback) or chain length limitations.
+   * With authmode set to optional, the TLS handshake is now aborted if the
+     verification of the peer's certificate failed due to an overlong chain or
+     a fatal error in the verify callback.
+
+Bugfix
+   * Add a check if iv_len is zero in GCM, and return an error if it is zero.
+     Reported by roberto. #716
+   * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
+     to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
+     always be implemented by pthread support. Fix for #696
+   * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
+     in the case of an error. Found by redplait. #590
+   * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
+     Reported and fix suggested by guidovranken in #740
+   * Fix a potential integer overflow in the version verification for DER
+     encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
+     to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
+     KNOX Security, Samsung Research America
+   * Fix a potential integer overflow in the version verification for DER
+     encoded X509 certificates. The overflow would enable maliciously
+     constructed certificates to bypass the certificate verification check.

+     arguments. Found by inestlerode. Fixes #557.
