2021.11

- Minimal supported BoringSSL version was increased to [45cf810d](https://github.com/google/boringssl/archive/45cf810dbdbd767f09f8cb0b0fcccd342c39041f.tar.gz) tag.

2021.10

- Added the verification part of eXtended Merkle Signature Scheme (XMSS) algorithm.
- Added FIPS-compliance mode for the library. More information can be found in the [Intel(R) IPP Cryptography FIPS Guide](./README_FIPS.md).

2021.9

- Added optimized RSA-2048 code for multi-buffer (8 buffers) Intel® AVX-512 implementation.
- Added Intel® Advanced Vector Extensions 2 (Intel® AVX2) vector extensions of Intel® AES New Instructions (Intel® AES-NI) optimization for AES-GCM algorithm.
- Changed the minimal supported OpenSSL version to 3.0.8 since 1.1.1 is not supported since September 2023.
- Raised the minimal CMake version to 3.18 since this is the minimal version that supports OpenSSL 3.0.8: https://cmake.org/cmake/help/latest/module/FindOpenSSL.html.

2021.8

- Crypto Multi-buffer library was extended with XTS mode of SM4 algorithm.

2021.7.1

- Added re-initialization API for AES-GCM context - ippsAES_GCMReinit. The use-case of this function is very specific, please, refer to the documentation for more details.

2021.7

- Mitigation for Frequency Throttling Side-Channel Attack ([Frequency Throttling Side Channel Software Guidance for Cryptography Implementations](https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/frequency-throttling-side-channel-guidance.html)) was added for ECB, CMAC and GCM modes of AES (for more details refer to ippsAESSetupNoise, ippsAES_GCMSetupNoise and ippsAES_CMACSetupNoise).
- Crypto Multi-buffer library was extended with CCM and GCM modes of SM4 algorithm.
- In Crypto Multi-buffer library in-place mode of executing (when pa_out == pa_inp) was fixed for SM4 CBC and CFB modes.
- New API that updates pointer to IppsHashMethod context inside the IppsHashState_rmf state was added (please, refer to ippsHashStateMethodSet_ API).
- ippsHMAC_Pack(_rmf), ippsHMAC_Unpack(_rmf) APIs were fixed - context id is set up properly now during the packing-unpacking process.
