Revision history for XML-PugiXML

0.10  2026-10-16
    - Avoid quadratic removal with retained stale handles.
    - Declare build and test prerequisites for older Perls.
    - Keep C compiler flags out of C++ builds.

0.09  2026-09-15
    - Fix use-after-free after reassigning the variable holding a document
    - Fix double free after an explicit DESTROY
    - Destroyed or uninitialized handles croak instead of crashing

0.08  2026-07-29
    - Fix use-after-free in $doc->select_nodes (results past the first got a
      bogus document handle; ->root segfaulted)
    - Fix use-after-free after remove_child/remove_attr (handles into the
      removed subtree now go stale instead of dangling)
    - Reject embedded NULs in lookup and removal args, not just mutation args
    - path() requires a single-character delimiter
    - CLONE_SKIP on all classes (ithreads double-free)
    - Keep perl's $Config{ccflags} instead of replacing them

0.07  2026-06-25
    - Add ensure_child / ensure_attr (get-or-create)
    - Expose FORMAT_NO_EMPTY_ELEMENT_TAGS and PUGIXML_VERSION constants
    - Support system pugixml >= 1.8 (Alien::pugixml 0.03)

0.06  2026-06-01
    - Catch C++ exceptions at the XS boundary
    - Reject cross-doc node args and embedded NULs
    - Don't leak caught C++ exception objects
    - Capture errno before formatting save error
    - Fix default indent (was " t", now tab)

0.05  2026-04-27
    - Don't double-encode raw UTF-8 byte input
    - Stale-handle checks on secondary node arguments
    - NODE_* type constants; Attr::set_name

0.03  2026-03-16
    - Fix XSUB stack panic on Perl 5.42+ (RC stack)
    - Fix floating-point test comparison portability

0.02  2026-03-14
    - Stale handle detection after reset/reload (no more segfaults)
    - XPath attribute selection support (//@id now works)
    - Attr::element() for parent navigation
    - UTF-8 input upgrade for all string parameters
    - Safe 64-bit integers on 32-bit Perl

    - Attribute types: as_int, as_uint, as_llong, as_ullong, as_double, as_bool
    - Parse/format constants for fine-grained control
    - UTF-8 support
    - Reference-counted memory model (nodes keep document alive)
