 mbed TLS ChangeLog (Sorted per branch, date)
 
+= Mbed TLS 3.0.0 branch released 2021-xx-xx
+
+API changes
+   * Remove HAVEGE module.
+     The design of HAVEGE makes it unsuitable for microcontrollers. Platforms
+     with a more complex CPU usually have an operating system interface that
+     provides better randomness. Instead of HAVEGE, declare OS or hardware RNG
+     interfaces with mbedtls_entropy_add_source() and/or use an entropy seed
+     file created securely during device provisioning. See
+     https://tls.mbed.org/kb/how-to/add-entropy-sources-to-entropy-pool for
+     more information.
+   * Add missing const attributes to API functions.
+   * Remove helpers for the transition from Mbed TLS 1.3 to Mbed TLS 2.0: the
+     header compat-1.3.h and the script rename.pl.
+   * Remove certs module from the API.
+     Transfer keys and certificates embedded in the library to the test
+     component. This contributes to minimizing library API and discourages
+     users from using unsafe keys in production.
+   * Move alt helpers and definitions.
+     Various helpers and definitions available for use in alt implementations
+     have been moved out of the include/ directory and into the library/
+     directory. The files concerned are ecp_internal.h and rsa_internal.h
+     which have also been renamed to ecp_alt.h and rsa_alt_helpers.h
+     respectively.
+   * Move internal headers.
+     Header files that were only meant for the library's internal use and
+     were not meant to be used in application code have been moved out of
+     the include/ directory. The headers concerned are bn_mul.h, aesni.h,
+     padlock.h, entropy_poll.h and *_internal.h.
+   * Drop support for parsing SSLv2 ClientHello
+     (MBEDTLS_SSL_SRV_SUPPORT_SSLV2_CLIENT_HELLO).
+   * Drop support for SSLv3 (MBEDTLS_SSL_PROTO_SSL3).
+   * Drop support for compatibility with our own previous buggy
+     implementation of truncated HMAC (MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT).
+   * Drop support for TLS record-level compression (MBEDTLS_ZLIB_SUPPORT).
+   * Drop support for RC4 TLS ciphersuites.
+   * Drop support for single-DES ciphersuites.
+   * Drop support for MBEDTLS_SSL_HW_RECORD_ACCEL.
+
+Requirement changes
+   * The library now uses the %zu format specifier with the printf() family of
+     functions, so requires a toolchain that supports it. This change does not
+     affect the maintained LTS branches, so when contributing changes please
+     bear this in mind and do not add them to backported code.
+
+Removals
+   * Remove the MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES
+     compile-time option, which was off by default. Users should not trust
+     certificates signed with SHA-1 due to the known attacks against SHA-1.
+     If needed, SHA-1 certificates can still be verified by using a custom
+     verification profile.
+
+   * Removed deprecated things in psa/crypto_compat.h. Fixes #4284
+   * Removed deprecated functions from hashing modules. Fixes #4280.
+   * Remove PKCS#11 library wrapper. PKCS#11 has limited functionality,
+     lacks automated tests and has scarce documentation. Also, PSA Crypto
+     provides a more flexible private key management.
+     More details on PCKS#11 wrapper removal can be found in the mailing list
+     https://lists.trustedfirmware.org/pipermail/mbed-tls/2020-April/000024.html
+   * Remove deprecated error codes. Fix #4283
+
+Features
+   * Add mbedtls_rsa_rsassa_pss_sign_ext() function allowing to generate a
+     signature with a specific salt length. This function allows to validate
+     test cases provided in the NIST's CAVP test suite. Contributed by Cédric
+     Meuter in PR #3183.
+
+Bugfix
+   * Fix premature fopen() call in mbedtls_entropy_write_seed_file which may
+     lead to the seed file corruption in case if the path to the seed file is
+     equal to MBEDTLS_PLATFORM_STD_NV_SEED_FILE. Contributed by Victor
+     Krasnoshchok in #3616.
+   * PSA functions creating a key now return PSA_ERROR_INVALID_ARGUMENT rather
+     than PSA_ERROR_INVALID_HANDLE when the identifier specified for the key
+     to create is not valid, bringing them in line with version 1.0.0 of the
+     specification. Fix #4271.
+   * Add printf function attributes to mbedtls_debug_print_msg to ensure we
+     get printf format specifier warnings.
+   * PSA functions other than psa_open_key now return PSA_ERROR_INVALID_HANDLE
+     rather than PSA_ERROR_DOES_NOT_EXIST for an invalid handle, bringing them
+     in line with version 1.0.0 of the specification. Fix #4162.
+   * Fix a bug in ECDSA that would cause it to fail when the hash is all-bits
+     zero. Fixes #1792
+   * mbedtls_mpi_read_string on "-0" produced an MPI object that was not treated
+     as equal to 0 in all cases. Fix it to produce the same object as "0".
+
+Changes
+   * Fix the setting of the read timeout in the DTLS sample programs.
+   * Add extra printf compiler warning flags to builds.
+   * Fix memsan build false positive in x509_crt.c with clang 11
+   * There is ongoing work for the next release (= Mbed TLS 3.0.0 branch to
+     be released 2021-xx-xx), including various API-breaking changes.

 Mbed TLS includes a reference implementation of the [PSA Cryptography API](#psa-cryptography-api). This is currently a preview for evaluation purposes only.
 
+Stability
+---------
+
+**Warning: the [`development`](https://github.com/ARMmbed/mbedtls/tree/development) branch of Mbed TLS currently has an unstable API.** It is where work is happening on the next major release of Mbed TLS. Until Mbed TLS 3.0 is released, if you need a stable API, please use the branch [`development_2.x`](https://github.com/ARMmbed/mbedtls/tree/development_2.x) instead.

+Migrating from Mbed TLS 2.x to Mbed TLS 3.0
+===========================================
+
+This guide details the steps required to migrate from Mbed TLS version 2.x to
+Mbed TLS version 3.0 or greater. Unlike normal releases, Mbed TLS 3.0 breaks
+compatibility with previous versions, so users (and alt implementors) might
+need to change their own code in order to make it work with Mbed TLS 3.0.
+
+Here's the list of breaking changes; each entry should help you answer these
+two questions: (1) am I affected? (2) if yes, what's my migration path?
+
+Some function parameters were made const
+----------------------------------------
+
+Various functions in the PK and ASN.1 modules had a `const` qualifier added to
+some of their parameters.
+
+This normally doesn't affect your code, unless you use pointers to reference
+those functions. In this case, you'll need to update the type of your pointers
+in order to match the new signature.
+
+Deprecated functions were removed from hashing modules
+------------------------------------------------------
+
+Modules: MD2, MD4, MD5, SHA1, SHA256, SHA512, MD.
+
+- The functions `mbedtls_xxx_starts()`, `mbedtls_xxx_update()`,
+  `mbedtls_xxx_finish()` and `mbedtls_xxx()` were removed. Please use the
+function with the same name with `_ret` appended and check the return value.
+- The function `mbedtls_md_init_ctx()` was removed; please use
+  `mbedtls_md_setup()` instead.
+- The functions `mbedtls_xxx_process()` were removed. You normally don't need
+  to call that from application code. However if you do (or if you want to
+provide your own version of that function), please use
+`mbedtls_internal_xxx_process()` instead, and check the return value.
+
+Deprecated error codes for hardware failures were removed
+---------------------------------------------------------
+
+- The macros `MBEDTLS_ERR_xxx_FEATURE_UNSUPPORTED` from various crypto modules
+  were removed; `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` is now used
+instead.
+- The macros `MBEDTLS_ERR_xxx_HW_ACCEL_FAILED` from various crypto modules
+  were removed; `MBEDTLS_ERR_PLATFORM_HW_ACCEL_FAILED` is now used instead.
+
+Deprecated names for PSA constants and types were removed
+---------------------------------------------------------
+
+Some constants and types that were present in beta versions of the PSA Crypto
+API were removed from version 1.0 of specification. Please switch to the new
+names provided by the 1.0 specification instead.
+
+Internal / alt-focused headers were moved to a private location
+----------------------------------------------------------------
+
+This shouldn't affect users who took care not to include headers that
+were documented as internal, despite being in the public include directory.
+
+If you're providing alt implementations of ECP or RSA, you'll need to add our
+`library` directory to your include path when building your alt
+implementations, and note that `ecp_internal.h` and `rsa_internal.h` have been
+renamed to `ecp_alt.h` and `rsa_alt_helpers.h` respectively.
+
+If you're a library user and used to rely on having access to a structure or
+function that's now in a private header, please reach out on the mailing list
+and explain your need; we'll consider adding a new API in a future version.
+
+Remove the option to allow SHA-1 by default in certificates
+-----------------------------------------------------------
+
+This does not affect users who use the default `config.h`, as this option was
+already off by default.
+
+If you used to enable `MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES` in your
+`config.h`, first please take a moment to consider whether you really still
+want to accept certificates signed with SHA-1 as those are considered insecure
+and no CA has issued them for a while. If you really need to allow SHA-1 in
+certificates, please set up a custom profile as follows:
+
+```
+const mbedtls_x509_crt_profile mbedtls_x509_crt_custom = {
+    MBEDTLS_X509_ID_FLAG( MBEDTLS_MD_SHA1 ) |
+    MBEDTLS_X509_ID_FLAG( /* other hash */ ) /* | etc */,
+    0xFFFFFFF,  /* Or specific PK algs */
+    0xFFFFFFF,  /* Or specific curves */
+    2048        /* Or another RSA min bitlen */
+};
+```
+Then pass it to `mbedtls_x509_crt_verify_with_profile()` if you're verifying
+a certificate chain directly, or to `mbedtls_ssl_conf_cert_profile()` if the
+verification happens during a TLS handshake.
+
+Remove the certs module from the library
+----------------------------------------
+
+This should not affect production use of the library, as the certificates and
+keys included there were never suitable for production use.
+
+However it might affect you if you relied on them for testing purposes. In
+that case, please embed your own test certificates in your test code; now that
+`certs.c` is out of the library there is no longer any stability guaranteed
+and it may change in incompatible ways at any time.
+
+Remove the HAVEGE module
+------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This only affects users who called the HAVEGE modules directly (not
+recommended), or users who used it through the entropy module but had it as the
+only source of entropy. If you're in that case, please declare OS or hardware
+RNG interfaces with `mbedtls_entropy_add_source()` and/or use an entropy seed
+file created securely during device provisioning. See
+<https://tls.mbed.org/kb/how-to/add-entropy-sources-to-entropy-pool> for more
+information.
+
+Remove support for parsing SSLv2 ClientHello
+--------------------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This only affects TLS servers that have clients who send an SSLv2 ClientHello.
+These days clients are very unlikely to do that. If you have a client that
+does, please try contacting them and encouraging them to upgrade their
+software.
+
+Remove support for SSL 3.0
+--------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This only affects TLS users who explicitly enabled `MBEDTLS_SSL_PROTO_SSL3`
+and relied on that version in order to communicate with peers that are not up
+to date. If one of your peers is in that case, please try contacting them and
+encouraging them to upgrade their software.
+
+Remove support for compatibility with old Mbed TLS's truncated HMAC
+-------------------------------------------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This only affects TLS users who enabled `MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT` and
+used the Truncated HMAC extension to communicate with peers using old version
+of Mbed TLS. Please consider using a CCM-8 ciphersuite instead of the
+Truncated HMAC extension, or convincing your peer to upgrade their version of
+Mbed TLS.
+
+Remove support for TLS record-level compression
+-----------------------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This only affects TLS users who enabled `MBEDTLS_ZLIB_SUPPORT`. This will not
+cause any failures however if you used to enable TLS record-level compression
+you may find that your bandwidth usage increases without compression. There's
+no general solution to this problem; application protocols might have their
+own compression mechanisms and are in a better position than the TLS stack to
+avoid variants of the CRIME and BREACH attacks.
+
+Remove support for TLS RC4-based ciphersuites
+---------------------------------------------
+
+This does not affect people who used the default `config.h` and the default
+list of ciphersuites, as RC4-based ciphersuites were already not negotiated in
+that case.
+
+Please switch to any of the modern, recommended ciphersuites (based on
+AES-GCM, AES-CCM or ChachaPoly for example) and if your peer doesn't support
+any, encourage them to upgrade their software.
+
+Remove support for TLS single-DES ciphersuites
+----------------------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+Please switch to any of the modern, recommended ciphersuites (based on
+AES-GCM, AES-CCM or ChachaPoly for example) and if your peer doesn't support
+any, encourage them to upgrade their software.
+
+Remove support for TLS record-level hardware acceleration
+---------------------------------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+This feature had been broken for a while so we doubt anyone still used it.
+However if you did, please reach out on the mailing list and let us know about
+your use case.
+
+Remove wrapper for libpkcs11-helper
+-----------------------------------
+
+This doesn't affect people using the default configuration as it was already
+disabled by default.
+
+If you used to rely on this module in order to store your private keys
+securely, please have a look at the key management facilities provided by the
+PSA crypto API. If you have a use case that's not covered yet by this API,
+please reach out on the mailing list.
+
+Remove config option `MBEDTLS_SSL_DEFAULT_TICKET_LIFETIME`
+----------------------------------------------------------
+
+This doesn't affect people using the default configuration.
+
+This option has not had any effect for a long time. Please use the `lifetime`
+parameter of `mbedtls_ssl_ticket_setup()` instead.
+
+Remove helpers for the transition from Mbed TLS 1.3 to Mbed TLS 2.0
+-------------------------------------------------------------------
+
+This only affects people who've been using Mbed TLS since before version 2.0
+and still relied on `compat-1.3.h` in their code.
+
+Please use the new names directly in your code; `scripts/rename.pl` (from any
+of the 2.x releases - no longer included in 3.0) might help you do that.

 If this function returns `PSA_SUCCESS` or `PSA_ERROR_BUFFER_TOO_SMALL`, it must fill `attributes` with the attributes of the key (except for the key identifier). On success, this function must also fill `key_buffer` with the key context.
 
-On entry, `psa_get_key_lifetime(attributes)` is the location at which the driver was declared and the persistence level `#PSA_KEY_LIFETIME_PERSISTENT`. The driver entry point may change the lifetime to one with the same location but a different persistence level. The standard attributes other than the key identifier and lifetime have the value conveyed by `PSA_KEY_ATTRIBUTES_INIT`.
+On entry, `psa_get_key_lifetime(attributes)` is the location at which the driver was declared and a persistence level with which the platform is attempting to register the key. The driver entry point may choose to change the lifetime (`psa_set_key_lifetime(attributes, lifetime)`) of the reported key attributes to one with the same location but a different persistence level, in case the driver has more specific knowledge about the actual persistence level of the key which is being retrieved. For example, if a driver knows it cannot delete a key, it may override the persistence level in the lifetime to `PSA_KEY_PERSISTENCE_READ_ONLY`. The standard attributes other than the key identifier and lifetime have the value conveyed by `PSA_KEY_ATTRIBUTES_INIT`.
 
 The output parameter `key_buffer` points to a writable buffer of `key_buffer_size` bytes. If the driver has a [`"builtin_key_size"` property](#key-format-for-opaque-drivers) property, `key_buffer_size` has this value, otherwise `key_buffer_size` has the value determined from the key type and size.

 ## Symmetric cryptography (AES) examples
 
-* [`aes/aescrypt2.c`](aes/aescrypt2.c): file encryption and authentication with a key derived from a low-entropy secret, demonstrating the low-level AES interface, the digest interface and HMAC.  
-  Warning: this program illustrates how to use low-level functions in the library. It should not be taken as an example of how to build a secure encryption mechanism. To derive a key from a low-entropy secret such as a password, use a standard key stretching mechanism such as PBKDF2 (provided by the `pkcs5` module). To encrypt and authenticate data, use a standard mode such as GCM or CCM (both available as library module).
-
 * [`aes/crypt_and_hash.c`](aes/crypt_and_hash.c): file encryption and authentication, demonstrating the generic cipher interface and the generic hash interface.
