+Remove the config option MBEDTLS_X509_ALLOW_UNSUPPORTED_CRITICAL_EXTENSION
+--------------------------------------------------------------------------
+
+This change does not affect users of the default configuration; it only affect
+users who enable this option.
+
+The X.509 standard says that implementations must reject critical extensions that
+they don't recognize, and this is what Mbed TLS does by default. This option
+allowed to continue parsing those certificates but didn't provide a convenient
+way to handle those extensions.
+
+The migration path from that option is to use the
+`mbedtls_x509_crt_parse_der_with_ext_cb()` function which is functionally
+equivalent to `mbedtls_x509_crt_parse_der()`, and/or
+`mbedtls_x509_crt_parse_der_nocopy()` but it calls the callback with every
+unsupported certificate extension and additionally the "certificate policies"
+extension if it contains any unsupported certificate policies.

+Remove MBEDTLS_CHECK_PARAMS option
+----------------------------------
+
+This change does not affect users who use the default configuration; it only
+affects users who enabled that option.
+
+The option `MBEDTLS_CHECK_PARAMS` (disabled by default) enabled certain kinds
+of “parameter validation”. It covered two kinds of validations:
+
+- In some functions that require a valid pointer, “parameter validation” checks
+that the pointer is non-null. With the feature disabled, a null pointer is not
+treated differently from any other invalid pointer, and typically leads to a
+runtime crash. 90% of the uses of the feature are of this kind.
+- In some functions that take an enum-like argument, “parameter validation”
+checks that the value is a valid one. With the feature disabled, an invalid
+value causes a silent default to one of the valid values.
+
+The default reaction to a failed check was to call a function
+`mbedtls_param_failed()` which the application had to provide. If this function
+returned, its caller returned an error `MBEDTLS_ERR_xxx_BAD_INPUT_DATA`.
+
+This feature was only used in some classic (non-PSA) cryptography modules. It was
+not used in X.509, TLS or in PSA crypto, and it was not implemented in all
+classic crypto modules.
+
+This feature has been removed. The library no longer checks for NULL pointers;
+checks for enum-like arguments will be kept or re-introduced on a case-by-case
+basis, but their presence will no longer be dependent on a compile-time option.
+
+Validation of enum-like values is somewhat useful, but not extremely important,
+because the parameters concerned are usually constants in applications.
+
+For more information see issue #4313.

+Keeping them in the library creates opportunities for misconfiguration
 and possibly downgrade attacks. More generally, more code means a larger attack
 surface, even if the code is supposedly not used.
 
 The migration path is to adopt the latest versions of the protocol.
+
+As a consequence of removing TLS 1.0, support for CBC record splitting was
+also removed, as it was a work-around for a weakness in this particular
+version. There is no migration path since the feature is no longer relevant.
+
+As a consequence of currently supporting only one version of (D)TLS (and in the
+future 1.3 which will have a different version negociation mechanism), support
+for fallback SCSV (RFC 7507) was also removed. There is no migration path as
+it's no longer useful with TLS 1.2 and later.
+
+As a consequence of currently supporting only one version of (D)TLS (and in the
+future 1.3 which will have a different concept of ciphersuites), support for
+configuring ciphersuites separately for each version via
+`mbedtls_ssl_conf_ciphersuites_for_version()` was removed. Use
+`mbedtls_ssl_conf_ciphersuites()` to configure ciphersuites to use with (D)TLS
+1.2; in the future a different API will be added for (D)TLS 1.3.

+Remove the padding parameters from mbedtls_rsa_init()
+-----------------------------------------------------
+
+This affects all users who use the RSA encryption, decryption, sign and
+verify APIs.
+
+The function mbedtls_rsa_init() no longer supports selecting the PKCS#1 v2.1
+encoding and its hash. It just selects the PKCS#1 v1.5 encoding by default. If
+you were using the PKCS#1 v2.1 encoding you now need, subsequently to the call
+to mbedtls_rsa_init(), to call mbedtls_rsa_set_padding() to set it.
+
+To choose the padding type when initializing a context, instead of
+```C
+    mbedtls_rsa_init(ctx, padding, hash_id);
+```
+, use
+```C
+    mbedtls_rsa_init(ctx);
+    mbedtls_rsa_set_padding(ctx, padding, hash_id);
+```
+
+To use PKCS#1 v1.5 padding, instead of
+```C
+    mbedtls_rsa_init(ctx, MBEDTLS_RSA_PKCS_V15, <ignored>);
+```
+, just use
+```C
+    mbedtls_rsa_init(ctx);

-/**
- * \def MBEDTLS_CHECK_PARAMS
- *
- * This configuration option controls whether the library validates more of
- * the parameters passed to it.
- *
- * When this flag is not defined, the library only attempts to validate an
- * input parameter if: (1) they may come from the outside world (such as the
- * network, the filesystem, etc.) or (2) not validating them could result in
- * internal memory errors such as overflowing a buffer controlled by the
- * library. On the other hand, it doesn't attempt to validate parameters whose
- * values are fully controlled by the application (such as pointers).
- *
- * When this flag is defined, the library additionally attempts to validate
- * parameters that are fully controlled by the application, and should always
- * be valid if the application code is fully correct and trusted.
- *
- * For example, when a function accepts as input a pointer to a buffer that may
- * contain untrusted data, and its documentation mentions that this pointer
- * must not be NULL:
- * - The pointer is checked to be non-NULL only if this option is enabled.
- * - The content of the buffer is always validated.
- *
- * When this flag is defined, if a library function receives a parameter that
- * is invalid:
- * 1. The function will invoke the macro MBEDTLS_PARAM_FAILED().
- * 2. If MBEDTLS_PARAM_FAILED() did not terminate the program, the function
- *   will immediately return. If the function returns an Mbed TLS error code,
- *   the error code in this case is MBEDTLS_ERR_xxx_BAD_INPUT_DATA.
- *
- * When defining this flag, you also need to arrange a definition for
- * MBEDTLS_PARAM_FAILED(). You can do this by any of the following methods:
- * - By default, the library defines MBEDTLS_PARAM_FAILED() to call a
- *   function mbedtls_param_failed(), but the library does not define this
- *   function. If you do not make any other arrangements, you must provide
- *   the function mbedtls_param_failed() in your application.
- *   See `platform_util.h` for its prototype.
- * - If you enable the macro #MBEDTLS_CHECK_PARAMS_ASSERT, then the
- *   library defines MBEDTLS_PARAM_FAILED(\c cond) to be `assert(cond)`.
- *   You can still supply an alternative definition of
- *   MBEDTLS_PARAM_FAILED(), which may call `assert`.
- * - If you define a macro MBEDTLS_PARAM_FAILED() before including `config.h`
- *   or you uncomment the definition of MBEDTLS_PARAM_FAILED() in `config.h`,
- *   the library will call the macro that you defined and will not supply
- *   its own version. Note that if MBEDTLS_PARAM_FAILED() calls `assert`,
- *   you need to enable #MBEDTLS_CHECK_PARAMS_ASSERT so that library source
- *   files include `<assert.h>`.
- *
- * Uncomment to enable validation of application-controlled parameters.

- * \brief   This macro tests the statement passed to it as a test step or

- *
- *          It assumes the library function under test cannot return a value and
- *          assumes errors can only be indicated by calls to
- *          MBEDTLS_PARAM_FAILED().
- *
- *          When MBEDTLS_CHECK_PARAMS is enabled, calls to the parameter failure

- *          can be made.
- *
- *          This macro is intended to test that functions returning void
- *          accept all of the parameter values they're supposed to accept - eg
- *          that they don't call MBEDTLS_PARAM_FAILED() when a parameter
- *          that's allowed to be NULL happens to be NULL.
- *
- *          Note: for functions that return something other that void,
- *          checking that they accept all the parameters they're supposed to
- *          accept is best done by using TEST_ASSERT() and checking the return
- *          value as well.
- *
- *          Note: this macro is available even when #MBEDTLS_CHECK_PARAMS is
- *          disabled, as it makes sense to check that the functions accept all
- *          legal values even if this option is disabled - only in that case,
- *          the test is more about whether the function segfaults than about
- *          whether it invokes MBEDTLS_PARAM_FAILED().
- *
- * \param   TEST                The test expression to be tested.
