-Changes
-   * Add unit tests for AES-GCM when called through mbedtls_cipher_auth_xxx()
-     from the cipher abstraction layer. Fixes #2198.
+Bugfix
+   * Fix a compilation issue with mbedtls_ecp_restart_ctx not being defined
+     when MBEDTLS_ECP_ALT is defined. Reported by jwhui. Fixes #2242.
+   * Run the AD too long test only if MBEDTLS_CCM_ALT is not defined.
+     Raised as a comment in #1996.
+   * Reduce the stack consumption of mbedtls_mpi_fill_random() which could
+     previously lead to a stack overflow on constrained targets.
+   * Add `MBEDTLS_SELF_TEST` for the mbedtls_self_test functions
+     in the header files, which missed the precompilation check. #971
+   * Fix returning the value 1 when mbedtls_ecdsa_genkey failed.
+   * Remove a duplicate #include in a sample program. Fixed by Masashi Honma #2326.
+   * Remove the mbedtls namespacing from the header file, to fix a "file not found"
+     build error. Fixed by Haijun Gu #2319.
+   * Fix signed-to-unsigned integer conversion warning
+     in X.509 module. Fixes #2212.
+   * Reduce stack usage of `mpi_write_hlp()` by eliminating recursion.
+     Fixes #2190.
 
-= mbed TLS 2.14.0+01b34fb316a5 branch released xxxx-xx-xx
+Changes
+   * Include configuration file in all header files that use configuration,
+     instead of relying on other header files that they include.
+     Inserted as an enhancement for #1371
+   * Add support for alternative CSR headers, as used by Microsoft and defined
+     in RFC 7468. Found by Michael Ernst. Fixes #767.
+   * Correct many misspellings. Fixed by MisterDA #2371.
+   * Provide an abstraction of vsnprintf to allow alternative implementations
+     for platforms that don't provide it. Based on contributions by Joris Aerts
+     and Nathaniel Wesley Filardo.
+   * Fix clobber list in MIPS assembly for large integer multiplication.
+     Previously, this could lead to functionally incorrect assembly being
+     produced by some optimizing compilers, showing up as failures in
+     e.g. RSA or ECC signature operations. Reported in #1722, fix suggested
+     by Aurelien Jarno and submitted by Jeffrey Martin.

-   * 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.
+Features
+   * Add a new config.h option of MBEDTLS_CHECK_PARAMS that enables validation
+     of parameters in the API. This allows detection of obvious misuses of the
+     API, such as passing NULL pointers. The API of existing functions hasn't
+     changed, but requirements on parameters have been made more explicit in
+     the documentation. See the corresponding API documentation for each
+     function to see for which parameter values it is defined. This feature is
+     disabled by default. See its API documentation in config.h for additional
+     steps you have to take when enabling it.

+     that it is now optional with the MBEDTLS_CHECK_PARAMS flag which by default
+     is off. That means that checks which were previously present by default
