 = mbed TLS 2.x.x branch released xxxx-xx-xx
 
+Features
+   * Add MBEDTLS_REMOVE_3DES_CIPHERSUITES to allow removing 3DES ciphersuites
+     from the default list (enabled by default). See
+     https://sweet32.info/SWEET32_CCS16.pdf.
+
 Bugfix
    * Fix a compilation issue with mbedtls_ecp_restart_ctx not being defined
      when MBEDTLS_ECP_ALT is defined. Reported by jwhui. Fixes #2242.
@@ -11,10 +16,59 @@
      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 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 signed-to-unsigned integer conversion warning
+     in X.509 module. Fixes #2212.
+   * Reduce stack usage of `mpi_write_hlp()` by eliminating recursion.
+     Fixes #2190.
+   * 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 returning the value 1 when mbedtls_ecdsa_genkey failed.
+   * 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.
+   * 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.
    * 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.
 
+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.
+   * Fix configuration queries in ssl-opt.h. #2030
+   * Ensure that ssl-opt.h can be run in OS X. #2029
+   * Reduce the complexity of the timing tests. They were assuming more than the
+     underlying OS actually guarantees.
+   * 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.
+   * 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).

 # Notes for maintainers
 # ---------------------
 #
+# The bulk of the code is organized into functions that follow one of the
+# following naming conventions:
+#  * pre_XXX: things to do before running the tests, in order.
+#  * component_XXX: independent components. They can be run in any order.
+#      * component_check_XXX: quick tests that aren't worth parallelizing.
+#      * component_build_XXX: build things but don't run them.
+#      * component_test_XXX: build and test.
+#  * support_XXX: if support_XXX exists and returns false then
+#    component_XXX is not run by default.
+#  * post_XXX: things to do after running the tests.
+#  * other: miscellaneous support functions.
+#
+# Each component must start by invoking `msg` with a short informative message.
+#
+# The framework performs some cleanup tasks after each component. This
+# means that components can assume that the working directory is in a
+# cleaned-up state, and don't need to perform the cleanup themselves.
+# * Run `make clean`.
+# * Restore `include/mbedtks/config.h` from a backup made before running
+#   the component.
+# * Check out `Makefile`, `library/Makefile`, `programs/Makefile` and
+#   `tests/Makefile` from git. This cleans up after an in-tree use of
+#   CMake.
+#
+# Any command that is expected to fail must be protected so that the
+# script keeps running in --keep-going mode despite `set -e`. In keep-going
+# mode, if a protected command fails, this is logged as a failure and the
+# script will exit with a failure status once it has run all components.
+# Commands can be protected in any of the following ways:
+# * `make` is a function which runs the `make` command with protection.
+#   Note that you must write `make VAR=value`, not `VAR=value make`,
+#   because the `VAR=value make` syntax doesn't work with functions.
+# * Put `report_status` before the command to protect it.
+# * Put `if_build_successful` before a command. This protects it, and
+#   additionally skips it if a prior invocation of `make` in the same
+#   component failed.
+#
 # The tests are roughly in order from fastest to slowest. This doesn't
 # have to be exact, but in general you should add slower tests towards
 # the end and fast checks near the beginning.
-#
-# Sanity checks have the following form:
-#   1. msg "short description of what is about to be done"
-#   2. run sanity check (failure stops the script)
-#
-# Build or build-and-test steps have the following form:
-#   1. msg "short description of what is about to be done"
-#   2. cleanup
-#   3. preparation (config.pl, cmake, ...) (failure stops the script)
-#   4. make
-#   5. Run tests if relevant. All tests must be prefixed with
-#      if_build_successful for the sake of --keep-going.

-Usage: $0 [OPTION]...
-  -h|--help             Print this help.
+Usage: $0 [OPTION]... [COMPONENT]...
+Run mbedtls release validation tests.
+By default, run all tests. With one or more COMPONENT, run only those.
+COMPONENT can be the name of a component or a shell wildcard pattern.
+
+Examples:
+  $0 "check_*"
+    Run all sanity checks.
+  $0 --no-armcc --except test_memsan
+    Run everything except builds that require armcc and MemSan.
+
+Special options:
+  -h|--help             Print this help and exit.
+  --list-all-components List all available test components and exit.
+  --list-components     List components supported on this platform and exit.
 
 General options:
   -f|--force            Force the tests to overwrite any modified files.
   -k|--keep-going       Run all tests and report errors at the end.
   -m|--memory           Additional optional memory tests.
      --armcc            Run ARM Compiler builds (on by default).
+     --except           Exclude the COMPONENTs listed on the command line,
+                        instead of running only those.
      --no-armcc         Skip ARM Compiler builds.
      --no-force         Refuse to overwrite modified files (default).
      --no-keep-going    Stop at the first error (default).
