Revision history for Perl module Regexp-Common-URI-RFC3986

2025102001  2026-04-02T11:30:10+0900
    - Initial release as a standalone CPAN distribution.

    - Provides Regexp::Common::URI::RFC3986, a complete set of regex building blocks
      transcribed from RFC 3986 (Uniform Resource Identifier: Generic Syntax, January 2005),
      superseding RFC 2396.

    - No dependency on Regexp::Common: all variables are plain interpolable strings
      exported via Exporter. The module can be used independently of the Regexp::Common
      framework.

    - Key improvements over Regexp::Common::URI::RFC2396:

      * $pct_encoded (replaces the old $escaped, kept as alias)
      * $sub_delims and $unreserved per RFC 3986 §2
      * Full path_* production set: $path_abempty, $path_absolute, $path_noscheme,
        $path_rootless, $path_empty
      * $IP_literal supporting IPv6 addresses and IPvFuture forms
      * $IPv6address as a faithful transcription of all 9 alternatives from RFC 3986
        Appendix A (the original RFC2396 module predates IPv6 literal support entirely)

    - Addition with $IPv6address relative to the PR originally submitted to Regexp-Common
      on 2025-10-20: the alternation set previously had only 8 forms, missing the 8th
      RFC 3986 alternative:

          [ *5( h16 ":" ) h16 ] "::" h16

      This would have caused addresses such as "::1", "fe80::1", and "2001:db8::1" to
      fail to match. All 9 alternatives are now correctly implemented.

    - Backward-compatibility aliases for RFC 2396 names are exported:
      $mark, $uric, $urics, $uric_no_slash, $escaped, $hostname, $domainlabel, $toplabel,
      $hostport, $server, $rel_segment, $rel_path, $path_segments, $abs_path, $path,
      $ftp_segments.

    - Optional non-normative Unicode/IDN helpers under the :IDN export tag:
      $IDN_DOT, $ACE, $IDN_U_LABEL, $IDN_HOST.

    - Test suite: 162 tests, fully standalone (no dependency on the t::Common helper from
      Regexp-Common).
