    Changes in liboqs:

    Updated to 0.16.0:

      Deprecation notice:

      - SPHINCS+ was removed in 0.16.0.

      Security issues:

      - Fixed uninitialized `encaps_derand` pointer dereference
      - CVE-2026-46344, CVE-2026-44518: Fixed out-of-bounds read in XMSS/XMSS^MT signature verification
        (bsc#1267007 bsc#1267001)
      - Fixed Integer underflow in CROSS `crypto_sign_open()`
      - Fixed incorrect array size when calling `secure_clean`
      - Implemented optimization barrier `OQS_MEM_BLACK_BOX` and applied to `ct_select` in FrodoKEM

      Significant change:

      FrodoKEM algorithm change:

      * Existing FrodoKEM in 0.15.0 was renamed to ephemeral
        FrodoKEM (`KEM_efrodokem_<640|976|1344>_<aes|shake>`), and
        the salted variant of FrodoKEM was added under the prior names
        (`KEM_frodokem_<640|976|1344>_<aes|shake>`).

        Ephemeral FrodoKEM is recommended for applications
        where each keypair will encapsulate only a small number
        of shared secrets and ciphertexts. Standard (salted)
        FrodoKEM is recommended for applications where each keypair
        is expected to encapsulate large number of ciphertexts. Please consult
        [upstream](https://github.com/microsoft/PQCrypto-LWEKE/#frodokem-learning-with-errors-key-
    encapsulation)
        for more details.

      * mldsa-native integration:

        mldsa-native is a secure, fast, and portable C90 implementation of the
        ML-DSA post-quantum signature standard. It also includes optimized
        builds for x86_64 and aarch64. It is now the default implementation
        behind `SIG_ml_dsa_<44|65|87>`.

      * Updated HQC implementation:

        The HQC implementations in liboqs were updated to 20250822
        spec. Its upstream switched from PQClean to the [official
        repo](https://gitlab.com/pqc-hqc/hqc). `KEM_hqc_<1|3|5>` is now enabled
        by default.

      * MQOM integration and memory-optimized build flag:

        MQOM is a third-round candidate in NIST's Additional Digital
        Signatures for the PQC Standardization Process. Portable,
        x86_64-optimized, and memory-optimized implementations were
        integrate?into liboqs under `OQS_ENABLE_SIG_MQOM`.


      * OpenSSH implementation of NTRU Prime:

        A public-domain OpenSSH implementation of NTRUPrime761
        replaced the PQClean implementation as the default backend for
        `KEM_ntruprime_sntrup761`.

        - New API: added an API function to check if a signature scheme supports signing with a context
