5902	XML-Parser-2.57	Bruce Dubbs	lfs-book	"New minor version.

2.57 2026-04-07

  Fixes:
    - Fix PE parsing regression that broke XML::Twig DTD
      round-tripping: defer parameter entity parsing activation to when a
      declaration handler is registered, preventing PE references from
      being consumed by the empty sub-parser instead of reaching the
      Default handler
    - Add regression tests for post-root character data
      routing and add ppport.h for XS backward compatibility macros
    - Add NULL check after XML_ParserCreate_MM to prevent
      segfault on memory allocation failure
    - Replace deprecated indirect object syntax in
      LWPExternEnt.pl (new URI(...) -> URI->new(...), etc.) for forward
      compatibility with Perl 5.36+ where 'use v5.36' disables the
      indirect feature. Also add 'use strict' to the file

  Improvements:
    - Add downstream CI testing for XML::XPath, XML::DOM, and
      XML::Twig to catch breakage in major consumers before release

  Maintenance:
    - Convert t/char_end_doc.t to Test::More; all 57 test files
      now consistently use Test::More
    - Expand CLAUDE.md with project conventions for generated
      files, releases, and testing
    - Add test coverage for load_encoding, xml_escape edge
      cases, and ContentModel API
    - Add test coverage for element_index, position_in_context,
      specified_attr, and setHandlers
    - Add test coverage for recognized_string, default_current,
      and original_string introspection methods
    - Add test coverage for context-tracking API (context,
      current_element, in_element, within_element, depth)
    - Add test coverage for parse_start/ExpatNB non-blocking
      parser API
    - Replace indirect object syntax in test files (t/decl.t,
      t/parament.t, t/external_ent.t)
    - Add test coverage for IO control character rejection in
      external entity paths

2.56 2026-04-02 (by Todd Rinaldo)

  Fixes:
    - Skip original_string test when expat lacks
      XML_CONTEXT_BYTES, fixing false test failures on platforms
      where libexpat is compiled without XML_CONTEXT_BYTES (e.g.
      DragonFlyBSD system expat)

2.55 2026-04-01 (by Todd Rinaldo)

  Fixes:
    - Fix struct-return ABI mismatch in XML_ExpatVersionInfo()
      by parsing the version string instead of using the struct return,
      which was corrupted when Perl and libexpat used different struct
      return conventions (-fpcc-struct-return vs -freg-struct-return)
    - Revert defaulthandle char
      routing and standalone string changes that broke downstream CPAN
      modules (XML-Twig, XML-DOM, XML-XPath)
    - Increase deep_nesting test depth from 600 to
      2048 to actually exercise the st_serial_stack reallocation code
      path
    - Update expat download URL from SourceForge to GitHub in
      the ""expat not found"" error message

  Improvements:
    - Add AddressSanitizer CI job for XS memory safety
      to catch heap buffer overflows and use-after-free bugs

  Maintenance:
    - Modernize last 4 print-ok test files (astress, namespaces,
      stream, skip) to Test::More with descriptive test names
    - Remove obsolete .travis.yml (project uses GitHub Actions)
