+- Update to version 4.0.1:
+  * Added missing doc sources to the distribution tarball (#503)
+  * Reworked C/C++ examples to avoid using new configuration aliases until the world has updated to re2c 4.0, made them compatible with C.
+  * A few build system changes: increased CMake minimum required version to 3.15, added missing dependencies on doc sources in Makefile.am.
+  * Fixed typos in docs.
+	* Added a generic technique for describing language backends based on the idea of syntax files (#450).
+	* Added support for new languages: D, Haskell, Java, JavaScript, OCaml, Python, V, Zig.
+	* Added new record API for all languages (enabled with --api record, re2c:api = record) and made it the default API for Haskell and OCaml.
+	* Renamed former “default API” to “simple API”, implemented it for all backends except Haskell and OCaml, and enabled by default API for C, D, Java, JavaScript, Python, V and Zig.
+	* Added new code generation model - recursive functions (enabled with --recursive-functions), primarily to be used for functional languages.
