+# Changelog
+
+Notable changes made to cppwg in each release.
+
+## [Unreleased]
+
+## [0.5.0] - 2026-08-15
+
+### Added
+
+- Automatic discovery of explicit C++ template instantiations: the
+  `discover_template_instantiations` option (scan the sources for
+  `template class Foo<2>;`), the package-level `source_cpp_patterns` glob
+  (default `["*.cpp"]`) naming which sources to scan, and `discover_arg_excludes`
+  (e.g. `{SPACE_DIM: [1]}`) to drop unwanted discovered instantiations by named
+  template parameter (#73).
+- `auto_includes` option to auto-include project-type headers, including
+  template-argument types (#97).
+- `typecasters` option to auto-include pybind11 typecasters (#95).
+- `exclude_inherited_overrides` option to skip redundant inherited-override
+  `.def`s (#101).
+- Enum wrapping: a module-level `enums` config list with an `export_values`
+  option controlling `.def(py::enum_...).export_values()` for unscoped enums (#113).
+- Struct wrapping and public data-member exposure (#116).
+- A `get_class_cpp_source_includes` hook for custom generators, allowing them to
+  declare their own C++ class source includes (#99).
+- Templated Python call syntax: `TemplateClass` (`Foo[2]`) and `TemplateMethod`
+  (`obj.Bar[T]()`) descriptors, wired into the shapes and cells examples (#70).
+- `cppwg genpackage` subcommand that generates a Python package layer from the
+  wrapper config. cppwg emits a `cppwg_package_model.json` describing the wrapped
+  modules and classes; `genpackage` turns that plus a `package_layout.yaml` into a
+  per-subpackage `_generated.py` (#102).
+- Coverage measurement via Codecov, targeting ~99% (#20).
+- Logfile rotation for the `-l`/`--logfile` option.
+- Support for Python 3.14 (#130).
+
+### Changed
+
+- Consolidated a templated class's instantiations into a single wrapper file pair
+  (`Foo.cppwg.cpp` / `Foo.cppwg.hpp`) instead of one pair per instantiation
+  (`Foo_2.cppwg.cpp`, `Foo_3.cppwg.cpp`, ...); the generated Python class names
+  (`Foo_2`, `Foo_3`) are unchanged (#30).
+- Replaced the hand-written `TemplateClassDict` scaffolding in the shapes and
+  cells examples with a generated `TemplateClass` stub. `TemplateClassDict` was a
+  module-level dict-like instance, so `Foo` was not a class; `TemplateClass` is
+  subclassed, making `Foo` a real class object that resolves `Foo[2]` via
+  `__class_getitem__` (like `list[int]`) (#70).
+- Sped up wrapper generation with a base-class virtual-signature index and
+  caching in the inherited-override check (#125).
+- Scoped source collection to the project's own source: CMake build trees are
+  pruned from the walk (any directory containing a `CMakeCache.txt`, assuming an
+  out-of-source build), and the explicit-instantiation scan is restricted to the
+  module `source_locations` when set. Previously a same-named class from a
+  vendored dependency or example tree under the source root could be conflated
+  with a wrapped class and corrupt its discovered/pruned template instantiations
+  (#125).
+- Unified the C++ argument/return exclusion options (`arg_type_excludes`,
+  `return_type_excludes`, `constructor_arg_type_excludes`) and applied them to
+  free functions as well as class methods and constructors (#91).
+- Housekeeping: consolidated duplicated logic into helpers, including exclusion
+  predicates, a single `BASE_INFO_OPTIONS` schema, and shared default-argument,
+  registration-name, and wrapper-filename helpers (#119).
+
+### Deprecated
+
+- `calldef_excludes`: use `arg_type_excludes` and/or `return_type_excludes`
+  instead. The parser now warns when it is used; it is still honoured as both
+  `arg_type_excludes` and `return_type_excludes` for backward compatibility
+  (#91).
+
+### Removed
+
+- The unused `extra_code` config option; use `prefix_code` / `suffix_code` (#92).
+
+### Fixed
+
+- `exclude_inherited_overrides` set at module or class level was silently ignored
+  (only package level was parsed) (#101).
+- A `KeyError` when a config listed explicit variables, a dead generated-file
+  skip in source collection, and a crash in the default `PackageInfo` when no
+  config file was given (#20).
+
+## [0.4.1] - 2026-06-30
+
+### Added
+
+- Cross-module inheritance (#88, #89).
+
+## [0.4.0] - 2026-06-29
+
+### Added
+
+- `--castxml_cflags` option (#78).
+- `--overwrite` option (#82).
+- Support for custom C++ exception classes (#84).
+
+### Changed
+
+- Dropped Python 3.8 and 3.9; added support for Python 3.13 (#76).
+- Switched the example projects' conda builds to rattler-build (#80).
+
+### Fixed
+
+- Handling of numeric arguments (#67, #68, #69).
+
+## [0.3.4] - 2024-11-22
+
+### Added
+
+- `--castxml_compiler` option (#66).
+
+### Changed
+
+- castxml is now a system requirement rather than being installed automatically
+  from pip; clang is now a recommended system dependency (#66).
+
+## [0.3.3] - 2024-11-13
+
+### Fixed
+
+- Stabilised class sorting for deterministic wrapper output (#65).
+
+## [0.3.2] - 2024-11-08
+
+### Added
+
+- Example conda build, with typecaster examples for PETSc, VTK and Boost uBLAS
+  (#63).
+
+## [0.3.1] - 2024-10-08
+
+### Changed
+
+- The example template-class syntax accepts types in arguments (#62).
+
+## [0.3.0] - 2024-09-30
+
+### Breaking Changes
+
+- The Python name format for a templated class `Foo<A,B>` changes from `FooA_B`
+  to `Foo_A_B` (#55).
+- Wrapper module names changed from `<module>.main.cpp` to
+  `_<package>_<module>.main.cppwg.cpp`, and a `.cppwg` extension was added to
+  `wrapper_header_collection.cppwg.hpp` (#58).
+
+### Added
+
+- Example of `Foo[2,2]`-style syntax for templated classes, and a
+  `source_file_path` config key (#60).
+
+### Changed
+
+- Cosmetic enhancements to the generated wrappers, and updates to YAML parsing
+  (#55, #56, #59, #61).
+
+## [0.2.1] - 2024-09-23
+
+### Added
+
+- Automatic sorting of classes by dependence (#53, #54).
+
+### Changed
+
+- Console log level is `ERROR` with `--quiet`, otherwise `INFO`; the file log
+  level is always `INFO` (#52).
+
+## [0.2.0] - 2024-09-16
+
+### Added
+
+- Prefix text for generated wrappers.
+- Excluding classes from wrapping via the `excluded` config key.
+- Listing of unknown classes in the logs.
+- Log output to a file via `--logfile`.
+- pybind11 fetched with CMake `FetchContent` in the example.
+
+## [0.1.0] - 2024-08-05
+
+### Added
+
+- Excluding constructors by signature (#47).
+- Prefix text for generated wrappers (#48).
+
+### Fixed
+
+- Template parameters in method default arguments (#44).
+- Wrappers for initializer lists of the form `foo = {}` in method default
+  arguments (#45).
+
+## [0.0.1] - 2024-05-07
+
+### Added
+
+- Locally pip-installable via `pip install .` and callable from the command line.
+- Tested on Python 3.8 to 3.12.
+
+### Fixed
+
+- Compatibility with C++ standards later than C++11.
+- Wrapping of templated classes with only a single explicit instantiation.
+- Wrapping of templated classes with signatures like `template <type A, B=A>`.
+- Handling of template parameters in method default arguments.
