 Security
-   * Fix overly strict DN comparison when looking for CRLs
-     belonging to a particular CA. This previously lead to
-     ignoring CRLs when the CRL's issuer name and the CA's
-     subject name differed in their string encoding (e.g.,
-     one using PrintableString and the other UTF8String) or
-     in the choice of upper and lower case. Reported by
-     HenrikRosenquistAndersson in #1784.
+   * Fix timing variations and memory access variations in RSA PKCS#1 v1.5
+     decryption that could lead to a Bleichenbacher-style padding oracle
+     attack. In TLS, this affects servers that accept ciphersuites based on
+     RSA decryption (i.e. ciphersuites whose name contains RSA but not
+     (EC)DH(E)). Discovered by Eyal Ronen (Weizmann Institute),  Robert Gillham
+     (University of Adelaide), Daniel Genkin (University of Michigan),
+     Adi Shamir (Weizmann Institute), David Wong (NCC Group), and Yuval Yarom
+     (University of Adelaide, Data61). The attack is described in more detail
+     in the paper available here: http://cat.eyalro.net/cat.pdf  CVE-2018-19608
+   * In mbedtls_mpi_write_binary(), don't leak the exact size of the number
+     via branching and memory access patterns. An attacker who could submit
+     a plaintext for RSA PKCS#1 v1.5 decryption but only observe the timing
+     of the decryption and not its result could nonetheless decrypt RSA
+     plaintexts and forge RSA signatures. Other asymmetric algorithms may
+     have been similarly vulnerable. Reported by Eyal Ronen, Robert Gillham,
+     Daniel Genkin, Adi Shamir, David Wong and Yuval Yarom.
+   * Wipe sensitive buffers on the stack in the CTR_DRBG and HMAC_DRBG
+     modules.
+
+API Changes
+   * The following functions in the random generator modules have been
+     deprecated and replaced as shown below. The new functions change
+     the return type from void to int to allow returning error codes when
+     using MBEDTLS_<MODULE>_ALT for the underlying AES or message digest
+     primitive. Fixes #1798.
+     mbedtls_ctr_drbg_update() -> mbedtls_ctr_drbg_update_ret()
+     mbedtls_hmac_drbg_update() -> mbedtls_hmac_drbg_update_ret()
+   * Extend ECDH interface to enable alternative implementations.
+
+New deprecations
+   * Deprecate mbedtls_ctr_drbg_update and mbedtls_hmac_drbg_update
+     in favor of functions that can return an error code.
+
+Bugfix
+   * Fix for Clang, which was reporting a warning for the bignum.c inline
+     assembly for AMD64 targets creating string literals greater than those
+     permitted by the ISO C99 standard. Found by Aaron Jones. Fixes #482.
+   * Fix runtime error in `mbedtls_platform_entropy_poll()` when run
+     through qemu user emulation. Reported and fix suggested by randombit
+     in #1212. Fixes #1212.
+   * Fix an unsafe bounds check when restoring an SSL session from a ticket.
+     This could lead to a buffer overflow, but only in case ticket authentication
+     was broken. Reported and fix suggested by Guido Vranken in #659.
+   * Add explicit integer to enumeration type casts to example program
+     programs/pkey/gen_key which previously led to compilation failure
+     on some toolchains. Reported by phoenixmcallister. Fixes #2170.

+Security
+   * Fix overly strict DN comparison when looking for CRLs belonging to a
+     particular CA. This previously led to ignoring CRLs when the CRL's issuer
+     name and the CA's subject name differed in their string encoding (e.g.,
+     one using PrintableString and the other UTF8String) or in the choice of
+     upper and lower case. Reported by Henrik Andersson of Bosch GmbH in issue
+     #1784.
+   * Fix a flawed bounds check in server PSK hint parsing. In case the
+     incoming message buffer was placed within the first 64KiB of address
+     space and a PSK-(EC)DHE ciphersuite was used, this allowed an attacker
+     to trigger a memory access up to 64KiB beyond the incoming message buffer,
+     potentially leading to an application crash or information disclosure.
+   * Fix mbedtls_mpi_is_prime() to use more rounds of probabilistic testing. The
+     previous settings for the number of rounds made it practical for an
+     adversary to construct non-primes that would be erroneously accepted as
+     primes with high probability. This does not have an impact on the
+     security of TLS, but can matter in other contexts with numbers chosen
+     potentially by an adversary that should be prime and can be validated.
+     For example, the number of rounds was enough to securely generate RSA key
+     pairs or Diffie-Hellman parameters, but was insufficient to validate
+     Diffie-Hellman parameters properly.
+     See "Prime and Prejudice" by by Martin R. Albrecht and Jake Massimo and
+     Kenneth G. Paterson and Juraj Somorovsky.

    * Add support for temporarily suspending expensive ECC computations after

      yet), and to existing functions in ECDH and SSL (currently only

-   * Extend RSASSA-PSS signature to allow slightly a smaller salt size.
-     Previously, PSS signature always used a salt with the same length as the

-     may be up to two bytes shorter. This allows the library to support all

 /**
- * \brief          Parse one or more certificates and add them
- *                 to the chained list. Parses permissively. If some
- *                 certificates can be parsed, the result is the number
- *                 of failed certificates it encountered. If none complete
- *                 correctly, the first error is returned.
+ * \brief          Parse one DER-encoded or one or more concatenated PEM-encoded
+ *                 certificates and add them to the chained list.
  *
- * \param chain    points to the start of the chain
- * \param buf      buffer holding the certificate data in PEM or DER format
- * \param buflen   size of the buffer
- *                 (including the terminating null byte for PEM data)
+ *                 For CRTs in PEM encoding, the function parses permissively:
+ *                 if at least one certificate can be parsed, the function
+ *                 returns the number of certificates for which parsing failed
+ *                 (hence \c 0 if all certificates were parsed successfully).
+ *                 If no certificate could be parsed, the function returns
+ *                 the first (negative) error encountered during parsing.
  *
- * \return         0 if all certificates parsed successfully, a positive number
- *                 if partly successful or a specific X509 or PEM error code
+ *                 PEM encoded certificates may be interleaved by other data
+ *                 such as human readable descriptions of their content, as
+ *                 long as the certificates are enclosed in the PEM specific
+ *                 '-----{BEGIN/END} CERTIFICATE-----' delimiters.
+ *
+ * \param chain    The chain to which to add the parsed certificates.
+ * \param buf      The buffer holding the certificate data in PEM or DER format.
+ *                 For certificates in PEM encoding, this may be a concatenation
+ *                 of multiple certificates; for DER encoding, the buffer must
+ *                 comprise exactly one certificate.
+ * \param buflen   The size of \p buf, including the terminating \c NULL byte
+ *                 in case of PEM encoded data.
+ *
+ * \return         \c 0 if all certificates were parsed successfully.
+ * \return         The (positive) number of certificates that couldn't
+ *                 be parsed if parsing was partly successful (see above).
