NOTE:

• --enable-heapmath is deprecated.
• In this release, the default cipher suite preference is updated to prioritize
  TLS_AES_256_GCM_SHA384 over TLS_AES_128_GCM_SHA256 when enabled.
• This release adds a sanity check for including wolfssl/options.h or
  user_settings.h.

PR stands for Pull Request, and PR references a GitHub pull request
number where the code change was added.

Vulnerabilities

• [Med] An OCSP (non stapling) issue was introduced in wolfSSL version 5.7.4
  when performing OCSP requests for intermediate certificates in a certificate
  chain. This affects only TLS 1.3 connections on the server side. It would not
  impact other TLS protocol versions or connections that are not using the
  traditional OCSP implementation. (Fix in pull request 8115)

New Feature Additions

• Add support for RP2350 and improve RP2040 support, both with RNG optimizations
  (PR 8153)
• Add support for STM32MP135F, including STM32CubeIDE support and HAL support
  for SHA2/SHA3/AES/RNG/ECC optimizations. (PR 8223, 8231, 8241)
• Implement Renesas TSIP RSA Public Enc/Private support (PR 8122)
• Add support for Fedora/RedHat system-wide crypto-policies (PR 8205)
• Curve25519 generic keyparsing API added with wc_Curve25519KeyToDer and
  wc_Curve25519KeyDecode (PR 8129)
• CRL improvements and update callback, added the functions
  wolfSSL_CertManagerGetCRLInfo and wolfSSL_CertManagerSetCRLUpdate_Cb (PR 8006)
• For DTLS, add server-side stateless and CID quality-of-life API. (PR 8224)

  not affected). (PR 8170)

  MacOS builds (PR 8282)
• Make Kyber and ML-KEM available individually and together. (PR 8143)
• Update configuration options to include Kyber/ML-KEM and fix defines used in
  wolfSSL_get_curve_name. (PR 8183)
• Make GetShortInt available with WOLFSSL_ASN_EXTRA (PR 8149)

• Add sanity checks for configuration methods, ensuring the inclusion of
  wolfssl/options.h or user_settings.h. (PR 8262)
