 The project aims to minimise the impact on users upgrading to newer versions of the library and it should not be necessary for a user to make any changes to their own code to work with a newer version of the library. Unless the user has made an active decision to use newer features, a newer generation of the library or a change has been necessary due to a security issue or other significant software defect, no modifications to their own code should be necessary. To achieve this, API compatibility is maintained between different versions of Mbed TLS on the main development branch and in LTS (Long Term Support) branches, as described in [BRANCHES.md](BRANCHES.md).
 
-To minimise such disruption to users, where a change to the interface is required, all changes to the ABI or API, even on the main development branch where new features are added, need to be justifiable by either being a significant enhancement, new feature or bug fix which is best resolved by an interface change. If there is an API change, the contribution, if accepted, will be merged only when there will be a major release.

If there is an API change, the contribution, if accepted, will be merged only when there is a major release.
 
-Where changes to an existing interface are necessary, functions in the public interface which need to be changed, are marked as 'deprecated'. This is done with the preprocessor symbols `MBEDTLS_DEPRECATED_WARNING` and `MBEDTLS_DEPRECATED_REMOVED`. Then, a new function with a new name but similar if not identical behaviour to the original function containing the necessary changes should be created alongside the existing deprecated function.
-
-When a build is made with the deprecation preprocessor symbols defined, a compiler warning will be generated to warn a user that the function will be removed at some point in the future, notifying users that they should change from the older deprecated function to the newer function at their own convenience.
-
-Therefore, no changes are permitted to the definition of functions in the public interface which will change the API. Instead the interface can only be changed by its extension. As described above, if a function needs to be changed, a new function needs to be created alongside it, with a new name, and whatever change is necessary, such as a new parameter or the addition of a return value.
+No changes are permitted to the definition of functions in the public interface which will change the API. Instead the interface can only be changed by its extension. Where changes to an existing interface are necessary, functions in the public interface which need to be changed are marked as 'deprecated'. If there is a strong reason to replace an existing function with one that has a slightly different interface (different prototype, or different documented behavior), create a new function with a new name with the desired interface. Keep the old function, but mark it as deprecated.
 
 Periodically, the library will remove deprecated functions from the library which will be a breaking change in the API, but such changes will be made only in a planned, structured way that gives sufficient notice to users of the library.

 Mbed TLS ChangeLog (Sorted per branch, date)
 
+= Mbed TLS 3.3.0 branch released 2022-12-14
+
+Default behavior changes
+   * Previously the macro MBEDTLS_SSL_DTLS_CONNECTION_ID implemented version 05
+     of the IETF draft, and was marked experimental and disabled by default.
+     It is now no longer experimental, and implements the final version from
+     RFC 9146, which is not interoperable with the draft-05 version.
+     If you need to communicate with peers that use earlier versions of
+     Mbed TLS, then you need to define MBEDTLS_SSL_DTLS_CONNECTION_ID_COMPAT
+     to 1, but then you won't be able to communicate with peers that use the
+     standard (non-draft) version.
+     If you need to interoperate with both classes of peers with the
+     same build of Mbed TLS, please let us know about your situation on the
+     mailing list or GitHub.
+
+Requirement changes
+   * When building with PSA drivers using generate_driver_wrappers.py, or
+     when building the library from the development branch rather than
+     from a release, the Python module jsonschema is now necessary, in
+     addition to jinja2. The official list of required Python modules is
+     maintained in scripts/basic.requirements.txt and may change again
+     in the future.
+
+New deprecations
+   * Deprecate mbedtls_asn1_free_named_data().
+     Use mbedtls_asn1_free_named_data_list()
+     or mbedtls_asn1_free_named_data_list_shallow().
+
+Features
+   * Support rsa_pss_rsae_* signature algorithms in TLS 1.2.
+   * make: enable building unversioned shared library, with e.g.:
+     "SHARED=1 SOEXT_TLS=so SOEXT_X509=so SOEXT_CRYPTO=so make lib"
+     resulting in library names like "libmbedtls.so" rather than
+     "libmbedcrypto.so.11".
+   * Expose the EC J-PAKE functionality through the Draft PSA PAKE Crypto API.
+     Only the ECC primitive with secp256r1 curve and SHA-256 hash algorithm
+     are supported in this implementation.
+   * Some modules can now use PSA drivers for hashes, including with no
+     built-in implementation present, but only in some configurations.
+     - RSA OAEP and PSS (PKCS#1 v2.1), PKCS5, PKCS12 and EC J-PAKE now use
+       hashes from PSA when (and only when) MBEDTLS_MD_C is disabled.
+     - PEM parsing of encrypted files now uses MD-5 from PSA when (and only
+       when) MBEDTLS_MD5_C is disabled.
+     See the documentation of the corresponding macros in mbedtls_config.h for
+     details.
+     Note that some modules are not able to use hashes from PSA yet, including
+     the entropy module. As a consequence, for now the only way to build with
+     all hashes only provided by drivers (no built-in hash) is to use
+     MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG.
+   * When MBEDTLS_USE_PSA_CRYPTO is enabled, X.509, TLS 1.2 and TLS 1.3 now
+     properly negotiate/accept hashes based on their availability in PSA.
+     As a consequence, they now work in configurations where the built-in
+     implementations of (some) hashes are excluded and those hashes are only
+     provided by PSA drivers. (See previous entry for limitation on RSA-PSS
+     though: that module only use hashes from PSA when MBEDTLS_MD_C is off).
+   * Add support for opaque keys as the private keys associated to certificates
+     for authentication in TLS 1.3.
+   * Add the LMS post-quantum-safe stateful-hash asymmetric signature scheme.
+     Signature verification is production-ready, but generation is for testing
+     purposes only. This currently only supports one parameter set
+     (LMS_SHA256_M32_H10), meaning that each private key can be used to sign
+     1024 messages. As such, it is not intended for use in TLS, but instead
+     for verification of assets transmitted over an insecure channel,
+     particularly firmware images.
+   * Add the LM-OTS post-quantum-safe one-time signature scheme, which is
+     required for LMS. This can be used independently, but each key can only
+     be used to sign one message so is impractical for most circumstances.
+   * Mbed TLS now supports TLS 1.3 key establishment via pre-shared keys.
+     The pre-shared keys can be provisioned externally or via the ticket
+     mechanism (session resumption).
+     The ticket mechanism is supported when the configuration option
+     MBEDTLS_SSL_SESSION_TICKETS is enabled.
+     New options MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_xxx_ENABLED
+     control the support for the three possible TLS 1.3 key exchange modes.
+   * cert_write: support for setting extended key usage attributes. A
+     corresponding new public API call has been added in the library,
+     mbedtls_x509write_crt_set_ext_key_usage().
+   * cert_write: support for writing certificate files in either PEM
+     or DER format.
+   * The PSA driver wrapper generator generate_driver_wrappers.py now
+     supports a subset of the driver description language, including
+     the following entry points: import_key, export_key, export_public_key,
+     get_builtin_key, copy_key.
+   * The new functions mbedtls_asn1_free_named_data_list() and
+     mbedtls_asn1_free_named_data_list_shallow() simplify the management
+     of memory in named data lists in X.509 structures.
+   * The TLS 1.2 EC J-PAKE key exchange can now use the PSA Crypto API.
+     Additional PSA key slots will be allocated in the process of such key
+     exchange for builds that enable MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED and
+     MBEDTLS_USE_PSA_CRYPTO.
+   * Add support for DTLS Connection ID as defined by RFC 9146, controlled by
+     MBEDTLS_SSL_DTLS_CONNECTION_ID (enabled by default) and configured with
+     mbedtls_ssl_set_cid().
+   * Add a driver dispatch layer for raw key agreement, enabling alternative
+     implementations of raw key agreement through the key_agreement driver
+     entry point. This entry point is specified in the proposed PSA driver
+     interface, but had not yet been implemented.
+   * Add an ad-hoc key derivation function handling EC J-PAKE to PMS
+     calculation that can be used to derive the session secret in TLS 1.2,
+     as described in draft-cragie-tls-ecjpake-01. This can be achieved by
+     using PSA_ALG_TLS12_ECJPAKE_TO_PMS as the key derivation algorithm.
+
+Security
+   * Fix potential heap buffer overread and overwrite in DTLS if
+     MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and
+     MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
+   * An adversary with access to precise enough information about memory
+     accesses (typically, an untrusted operating system attacking a secure
+     enclave) could recover an RSA private key after observing the victim
+     performing a single private-key operation if the window size used for the
+     exponentiation was 3 or smaller. Found and reported by Zili KOU,
+     Wenjian HE, Sharad Sinha, and Wei ZHANG. See "Cache Side-channel Attacks
+     and Defenses of the Sliding Window Algorithm in TEEs" - Design, Automation
+     and Test in Europe 2023.
+
+Bugfix
+   * Refactor mbedtls_aes_context to support shallow-copying. Fixes #2147.
+   * Fix an issue with in-tree CMake builds in releases with GEN_FILES
+     turned off: if a shipped file was missing from the working directory,
+     it could be turned into a symbolic link to itself.
+   * Fix a long-standing build failure when building x86 PIC code with old
+     gcc (4.x). The code will be slower, but will compile. We do however
+     recommend upgrading to a more recent compiler instead. Fixes #1910.
+   * Fix support for little-endian Microblaze when MBEDTLS_HAVE_ASM is defined.
+     Contributed by Kazuyuki Kimura to fix #2020.
+   * Use double quotes to include private header file psa_crypto_cipher.h.
+     Fixes 'file not found with <angled> include' error
+     when building with Xcode.
+   * Fix handling of broken symlinks when loading certificates using
+     mbedtls_x509_crt_parse_path(). Instead of returning an error as soon as a
+     broken link is encountered, skip the broken link and continue parsing
+     other certificate files. Contributed by Eduardo Silva in #2602.
+   * Fix an interoperability failure between an Mbed TLS client with both
+     TLS 1.2 and TLS 1.3 support, and a TLS 1.2 server that supports
+     rsa_pss_rsae_* signature algorithms. This failed because Mbed TLS
+     advertised support for PSS in both TLS 1.2 and 1.3, but only
+     actually supported PSS in TLS 1.3.
+   * Fix a compilation error when using CMake with an IAR toolchain.
+     Fixes #5964.
+   * Fix a build error due to a missing prototype warning when
+     MBEDTLS_DEPRECATED_REMOVED is enabled.
+   * Fix mbedtls_ctr_drbg_free() on an initialized but unseeded context. When
+     MBEDTLS_AES_ALT is enabled, it could call mbedtls_aes_free() on an
+     uninitialized context.
+   * Fix a build issue on Windows using CMake where the source and build
+     directories could not be on different drives. Fixes #5751.
+   * Fix bugs and missing dependencies when building and testing
+     configurations with only one encryption type enabled in TLS 1.2.
+   * Provide the missing definition of mbedtls_setbuf() in some configurations
+     with MBEDTLS_PLATFORM_C disabled. Fixes #6118, #6196.
+   * Fix compilation errors when trying to build with
+     PSA drivers for AEAD (GCM, CCM, Chacha20-Poly1305).
+   * Fix memory leak in ssl_parse_certificate_request() caused by
+     mbedtls_x509_get_name() not freeing allocated objects in case of error.
+     Change mbedtls_x509_get_name() to clean up allocated objects on error.
+   * Fix build failure with MBEDTLS_RSA_C and MBEDTLS_PSA_CRYPTO_C but not
+     MBEDTLS_USE_PSA_CRYPTO or MBEDTLS_PK_WRITE_C. Fixes #6408.
+   * Fix build failure with MBEDTLS_RSA_C and MBEDTLS_PSA_CRYPTO_C but not
+     MBEDTLS_PK_PARSE_C. Fixes #6409.
+   * Fix ECDSA verification, where it was not always validating the
+     public key. This bug meant that it was possible to verify a
+     signature with an invalid public key, in some cases. Reported by
+     Guido Vranken using Cryptofuzz in #4420.
+   * Fix a possible null pointer dereference if a memory allocation fails
+     in TLS PRF code. Reported by Michael Madsen in #6516.
+   * Fix TLS 1.3 session resumption. Fixes #6488.
+   * Add a configuration check to exclude optional client authentication
+     in TLS 1.3 (where it is forbidden).
+   * Fix a bug in which mbedtls_x509_crt_info() would produce non-printable
+     bytes when parsing certificates containing a binary RFC 4108
+     HardwareModuleName as a Subject Alternative Name extension. Hardware
+     serial numbers are now rendered in hex format. Fixes #6262.
+   * Fix bug in error reporting in dh_genprime.c where upon failure,
+     the error code returned by mbedtls_mpi_write_file() is overwritten
+     and therefore not printed.
+   * In the bignum module, operations of the form (-A) - (+A) or (-A) - (-A)
+     with A > 0 created an unintended representation of the value 0 which was
+     not processed correctly by some bignum operations. Fix this. This had no
+     consequence on cryptography code, but might affect applications that call

-    * Add the LMS post-quantum-safe stateful-hash asymmetric signature scheme.
-      Signature verification is production-ready, but generation is for testing
-      purposes only. This currently only supports one parameter set
-      (LMS_SHA256_M32_H10), meaning that each private key can be used to sign
-      1024 messages. As such, it is not intended for use in TLS, but instead for
-      verification of assets transmitted over an insecure channel, particularly
-      firmware images.
-    * Add the LM-OTS post-quantum-safe one-time signature scheme, which is
-      required for LMS. This can be used independently, but each key can only be
-      used to sign one message so is impractical for most circumstances.

-   * Some modules can now use PSA drivers for hashes, including with no

-     - RSA OAEP and PSS (PKCS#1 v2.1), PKCS5, PKCS12 and EC J-PAKE now use

-     - PEM parsing of encrypted files now uses MD-5 from PSA when (and only

+     * This function is not constant-trace: its memory accesses depend on the

+     * table element was used, and from distinguishing between multiplications
+     * and squarings. Firstly, when multiplying by an element of the window
+     * W[i], we do a constant-trace table lookup to obfuscate i. This leaves
+     * squarings as having a different memory access patterns from other
+     * multiplications. So secondly, we put the accumulator X in the table as
+     * well, and also do a constant-trace table lookup to multiply by X.
+     *
+     * This way, all multiplications take the form of a lookup-and-multiply.

+     * trace, an adversary is unlikely to be able to observe the exact
+     * patterns.
+     *
+     * An adversary may still be able to recover the exponent if they can
+     * observe both memory accesses and branches. However, branch prediction

+     * data, which is defeated by randomized blinding.
