 Ginger Development News
 =======================
 
+Ginger Version 0.9.2
+--------------------
+
+Ubuntu SNAP Packaging
+~~~~~~~~~~~~~~~~~~~~~
+Canonical have a new 'universal' package format they call Snap. Ginger has been
+rewritten to be Snap compliant. This is the fastest and simplest way to
+install, update and remove Ginger, at least on Ubuntu. (There are other 
+competing formats, such as Flatpak, that would also be possible.)
+
+    % sudo snap install --devmode https://github.com/Spicery/ginger/releases/download/v0.9.2/ginger_0.9.2_amd64.snap
+
+Command-Line Interface
+~~~~~~~~~~~~~~~~~~~~~~
+The command-line interface has been substantially rewritten to make GNU readline
+part of the core functionality. This eliminates the dependency on rlwrap, although
+that remains a useful tool for developers e.g. for gvmtest. This simplifies the
+delivery and setup and the ginger executable is now a genuine executable and not
+a shebang script - the latter unfortunately being more limited in terms of 
+scripting.
+
+The ginger executable now takes a 'command' argument that selects the actual
+program:
+
+    % ginger <COMMAND> <OPTIONS>
+
+The program is selected by the very simple strategy of prefixing the command 
+with "ginger-". Hence, as an example, the following two command-line are identical:
+
+    % ginger admin 
+    % ginger-admin
+
+If omitted the command defaults to "cli", and invokes "ginger-cli". This is an abbreviation for "command line interface".
+
+Refactorings
+~~~~~~~~~~~~
+* The old appginger executable, which has been without any real use for several
+  years, has been properly retired. The few places it was used have been 
+  properly replace by ginger-script.
+* Reduction in the use of old-style C-macros in favour of C++ constants.
+* System-functions have been re-organised to make it possible to manage them
+  in a modular way. This functionality has not been used as yet.
+* The system-functions table has been renamed to something more sensible.
