        - Lower the min perl from 5.16 to 5.10
        - verify() returns undef through XSRETURN_UNDEF rather than an
          &PL_sv_undef RETVAL, which xsubpp mortalises: harmless from perl
          5.20, a spent immortal reference before it.

        - SHA-1: sha1 and hmac_sha1 at the Perl level, and jws_abi
          version 2 appends sha1, hmac_sha1 and hmac_sha512 to the
          table. SHA-1 exists for HMAC-based protocols whose interop
          default is SHA-1 - RFC 6238 TOTP above all; no JWS algorithm
          reaches it and the JWS algorithm table is unchanged.
        - The POD's consumer recipe now checks the table version with
          >= against the version the consumer needs, never equality;
          the 0.03 fix reached the checks but not the documentation
          that teaches new consumers to write them.
        - Vector tests: FIPS 180 SHA-1, all seven RFC 2202 HMAC-SHA1
          cases, RFC 4231 HMAC-SHA512.

        - FIX: change abi version checks from == to <=

        Fix load failure on LibreSSL (OpenBSD base): cjws_key_alloc no
        longer calls OPENSSL_zalloc, which LibreSSL does not provide -
        the implicit declaration only surfaced at dlopen as an
        undefined symbol.
        Report NA rather than an inconclusive result when libcrypto is
        missing or predates OpenSSL 1.1.0 / LibreSSL 2.7.

0.01    2026-08-15
        First version.
