+
+## [0.3.25] - 2022-03-31
+
+### Added
+
+- Support for parsing `-Wl` linker arguments from the `Libs` lines and
+  passing them to the linker as well as making them available via
+  `Library::ld_args` (#131).
+
+### Changed
+
+- Use SPDX license format and remove obsolete badge info (#129).
+
+## [0.3.24] - 2021-12-11
+
+### Fixed
+
+- Re-add `target_supported()`, which was accidentally removed in 0.3.15 (#128).
+
+## [0.3.23] - 2021-12-06
+
+### Changed
+
+- Improve error messages when a `pkg-config` package can't be found (#127).
+
+## [0.3.22] - 2021-10-24
+
+### Fixed
+
+- `pkg-config` compiles again with Rust 1.30 or newer. 0.3.21 accidentally
+  made use of API only available since 1.40 (#124, #125).
+
+### Changed
+
+- Switched from Travis to GitHub Actions for the CI. Travis is dysfunctional
+  since quite some time (#126).
+
+## [0.3.21] - 2021-10-22
+
+### Fixed
+
+- Tests succeed again on macOS (#122).
+
+### Changed
+
+- Improve error message in case of missing pkg-config and provide instructions
+  how it can be installed (#121).
+
+## [0.3.20] - 2021-09-25
+
+### Fixed
+
+- Use target-specific pkg-config consistently everywhere (#121, #118).
+
+## [0.3.19] - 2020-10-13
+
+### Added
+
+- Add `README.md` to be displayed on crates.io (#111).
+
+- Support for `-isystem`, `-iquote` and `-idirafter` include flags (#115).
+
+### Changed
+
+- Improve documentation for cross-compilation (#113).
+
+- Allow overriding system root via the `PKG_CONFIG_SYSROOT_DIR` or `SYSROOT`
+  environment variable (#82).
+
+## [0.3.18] - 2020-07-11
+
+### Fixed
+
+- Use `env::var_os()` almost everywhere to handle non-UTF8 paths in
+  environment variables, and also improve error handling around environment
+  variable handling (#106).
+
+### Changed
+
+- Default the `env_metadata` build parameter to `true` instead of `false`.
+  Whenever a pkg-config related environment variable changes it would make
+  sense to rebuild crates that use pkg-config, or otherwise changes might not
+  be picked up. As such the previous default didn't make much sense (#105).
+

+- Fix various clippy warnings
+
+### Added
