v2.15.0: Sep 15 2025

### Major changes

The API documentation is now generated with Doxygen. Building the
documentation requires the new --with-docs configuration option as well
as Doxygen, xsltproc and the DocBook 4 XSLT stylesheets.

The Python bindings are disabled by default now. Building the bindings
also requires Doxygen.

Support for Schematron is now disabled by default.

The parser option XML_PARSE_UNZIP is now required to read compressed data.

HTML serialization and handling of character encodings is more in line
with the HTML5 spec now.

More accessors for xmlParserCtxt were added.

### Deprecations

More internal functions and struct members were deprecated.

### Removals

The built-in HTTP client and support for LZMA compression were removed.

The custom Windows build system in `win32` was removed in favor of CMake.

### Planned removals

The Python bindings and support for Schematron validation are planned to
be removed in the 2.16 release.

The following features are considered for removal:

- Modules API (xmlmodule.h)
- Support for zlib compressed file I/O

RELAX NG support is still in a bad state and a long-term removal
candidate.
