+## [Unreleased]
+
+## [1.0.0] - 2023-09-24
+
+### Added
+
+- This changelog to instil a process of clean version documentation for the library.
+- Common Makefile
+- Initial implementations of atari functions:
+  - network_close, network_open, network_read, network_write, network_status
+- cross platform BDD testing framework, atari implementation done, c64 skeleton created
+
+## Notes
+
+All notable changes to this project will be documented in this file.

+# The "Native Win32" GNU Make contains quite some workarounds to get along with

+# actually activate those workarounds. Especially does $(SHELL) NOT contain the
+# value 'cmd.exe'. So the usual way to determine if cmd.exe is being used is to
+# execute the command 'echo' without any parameters. Only cmd.exe will return a
+# non-empy string - saying 'ECHO is on/off'.
+#
+# Many "Native Win32" prorams accept '/' as directory delimiter just fine. How-
+# ever the internal commands of cmd.exe generally require '\' to be used.
+#
+# cmd.exe has an internal command 'mkdir' that doesn't understand nor require a
+# '-p' to create parent directories as needed.
