* Thu Nov 16 2023 David Anes - Removed patches (already in upstream):
* libxml2-CVE-2023-39615.patch
* libxml2-CVE-2023-45322.patch
* libxml2-make-XPATH_MAX_NODESET_LENGTH-configurable.patch
* python312.patch- Update to 2.12.0:
* Major changes: - Most of the known issues leading to quadratic behavior in the XML parser were fixed. Internal hash tables were rewritten to reduce memory consumption. - Starting with this release, it should be enough to add the - -with-legacy configuration option to provide maximum ABI compatibility. - libxml2 will now store global variables in thread-local storage if supported by the compiler. This avoids allocating the data lazily which can result in a fatal error condition. - A new API function xmlCheckThreadLocalStorage was added so the allocation can be checked earlier if compiler TLS is not supported. - To prepare for future improvements, some API functions now expect or return a const xmlError struct. - Several cyclic dependencies in public header files were fixed. - Refactoring of the encoding code has been mostly completed. Calling xmlSwitchEncoding from client code is now fully supported, for example to override the encoding for the push parser. - When parsing data from memory, libxml2 will now stream data chunk by chunk instead of copying the whole buffer (possibly twice with encodings), reducing peak memory consumption considerably. - A new API function xmlCtxtSetMaxAmplification was added to allow parsing of files that would otherwise trigger the billion laughs protection. - Several bugs in the regex determinism checks were fixed. Invalid XML Schemas which previous versions erroneously accepted will now be rejected.
* Deprecations - globals: Deprecate xmlLastError - parser: Deprecate global parser options - win32: Deprecate old Windows build system
* Bug fixes - parser: Stop switching to ISO-8859-1 on encoding errors - parser: Support encoded external PEs in entity values - string: Fix UTF-8 validation in xmlGetUTF8Char - SAX2: Allow multiple top-level elements - parser: Update line number after coalescing text nodes - parser: Check for truncated multi-byte sequences

* Wed May 03 2023 David Anes - Rebased patches:
* libxml2-make-XPATH_MAX_NODESET_LENGTH-configurable.patch
* libxml2-python3-unicode-errors.patch- Update to 2.11.1:
* Fixes build and ABI issues. - cmake: Fix va_copy detection (Luca Niccoli) - libxml.m4: Fix quoting - Link with --undefined-version - libxml2.syms: Revert removal of version information- Update to 2.11.0:
* Major changes - Protection against entity expansion attacks, also known as \"billion laughs\" has been greatly improved. Malicious files should be detected reliably now and false positives should be reduced. It is possible though that large documents which make heavy use of entities are rejected now. - This release finally fixes symbol visibility on UNIX systems. Internal symbols will now be hidden. While these symbols were never declared in public headers, it was still possible to declare them manually. Now this won\'t work. - All symbol information has been removed from the ELF version script to fix link errors with --no-undefined-version. The version nodes are kept so it should still be possible to run binaries linked against older versions. - About 90 memory errors in code paths handling malloc failures have been fixed. While these issues shouldn\'t impact security, this improves robustness under memory pressure. - The XInclude engine has been reworked to properly support nested includes. - Several cases of quadratic behavior in the XML push parser have been fixed. - Refactoring has begun on some buffering and encoding code with the goal of simplifying this part of the code base and improving error reporting.
* Other highlights: - Consolidated private header files. - Major rework of the autoconf build. - Deprecated several outdated and internal functions.
* Security - Fix use-after-free in xmlParseContentInternal() (David Kilzer) - xmllint: Fix use-after-free with --maxmem - parser: Fix OOB read when formatting error message - entities: Rework entity amplification checks
