= mbed TLS x.x.x branch released xxxx-xx-xx
+Features
+ * Add new crypto primitives from RFC 7539: stream cipher Chacha20, one-time
+ authenticator Poly1305 and AEAD construct Chacha20-Poly1305. Contributed by
+ Daniel King (#485).
+ * Add platform support for the Haiku OS. (https://www.haiku-os.org).
+ Contributed by Augustin Cavalier.
+ * Make the receive and transmit buffers independent sizes, for situations
+ where the outgoing buffer can be fixed at a smaller size than the incoming
+ buffer, which can save some RAM. If buffer lengths are kept equal, there
+ is no functional difference. Contributed by Angus Gratton, and also
+ independently contributed again by Paul Sokolovsky.
+
Bugfix
+ * Fix the key_app_writer example which was writing a leading zero byte which
+ was creating an invalid ASN.1 tag. Found by Aryeh R. Fixes #1257.
+ * Fix compilation error on C++, because of a variable named new.
+ Found and fixed by Hirotaka Niisato in #1783.
+ * Fix "no symbols" warning issued by ranlib when building on Mac OS X. Fix
+ contributed by tabascoeye in pull request #1600.
+ * Clarify documentation for mbedtls_ssl_write() to include 0 as a valid
+ return value. Found by @davidwu2000. #839
+ * Fix a memory leak in mbedtls_x509_csr_parse(), found by catenacyber,
+ Philippe Antoine. Fixes #1623.
+ * Remove unused headers included in x509.c. Found by Chris Hanson and fixed
+ by Brendan Shanks. Part of a fix for #992.
+ * Fix compilation error when MBEDTLS_ARC4_C is disabled and
+ MBEDTLS_CIPHER_NULL_CIPHER is enabled. Found by TrinityTonic in #1719.
+ * Fix the inline assembly for the MPI multiply helper function for i386 and
+ i386 with SSE2. Found by László Langó. Fixes #1550
* Fix namespacing in header files. Remove the `mbedtls` namespacing in
the `#include` in the header files. Resolves #857
+Changes
+ * Change the shebang line in Perl scripts to look up perl in the PATH.
+ Contributed by fbrosson.
