expat-2.9.0

[Joe Locash]

Release 2.9.0 Mon October 5 2026
        Security fixes:
           #1392  CVE-2026-102633 -- Integer overflow in function
                    expat_realloc on 32bit platforms
           #1393  CVE-2026-77214 -- Validate parameter `len` against available
                    buffer capacity in XML_ParseBuffer

        Bug fixes:
           #1387  lib: Handle OOM when copying encodingName in XML_ParserReset

        New features:
           #1327  lib: Introduce new "Properties API" to get and set
                    scalar properties for a single parser instance.
                    There are six new functions:
                    - XML_GetPropertyBool
                    - XML_GetPropertyDouble
                    - XML_GetPropertyUInt64
                    - XML_SetPropertyBool
                    - XML_SetPropertyDouble
                    - XML_SetPropertyUInt64
                    And two new enums:
                    - XML_Prop_Error
                    - XML_Parser_Property
           #1323  lib: Introduce five new 64bit location API functions:
                    - XML_GetCurrentByteCount64
                    - XML_GetCurrentByteIndex64
                    - XML_GetCurrentColumnNumber64
                    - XML_GetCurrentLineNumber64
                    - XML_GetInputContext64
                    These five functions closely mirror their predecessors
                    but are not prone to 32bit integer wrap-around.

        Other changes:
           #1391  docs: Document the scope of function XML_GetErrorCode
           #1395  docs: Document length expectations for XML_ParseBuffer
           #1394  lib: Call unknown encoding release before parser teardown
     #1370 #1373  lib: Drop (disabled-by-default) attribute info feature
                    These things are now gone:
                    - Public function XML_GetAttributeInfo
                    - Public struct XML_AttrInfo
                    - Macro XML_ATTR_INFO
                    These things are now causing build errors:
                    - Configure option --enable-xml-attr-info
                    - CMake option -DEXPAT_ATTR_INFO=ON
     #1379 #1382  lib: Drop (disabled-by-default) minimum size feature
                    These things are now gone:
                    - Macro XML_MIN_SIZE
                    These things are now causing build errors:
                    - Configuring with -DXML_MIN_SIZE for CPPFLAGS/CFLAGS
                    - CMake option -DEXPAT_MIN_SIZE=ON
     #1323 #1411  lib: Deprecate macro XML_LARGE_SIZE (use the new 64bit
                    location API functions instead please)
           #1323  lib: Deprecate five location API functions that are cursed
                    with integer wrap-around:
                    - XML_GetCurrentByteCount
                    - XML_GetCurrentByteIndex
                    - XML_GetCurrentColumnNumber
                    - XML_GetCurrentLineNumber
                    - XML_GetInputContext
           #1399  lib: Guard against out-of-handler use of XML_DefaultCurrent
           #1400  lib: Use size_t for bytesAllocated and peakBytesAllocated
  #1401 #1402 ..
     #1404 #1405  lib|xmlwf|tests: Unify use of xcslen, xcscmp and xcsncmp
           #1406  xmlwf: Add missing `#include "expat.h"`
     #1389 #1396  Version info bumped from 13:5:12 (libexpat*.so.1.12.5)
                    to 14:0:13 (libexpat*.so.1.13.0); see https://verbump.de/
