+@** Difference and Mean.
+
+\noindent Some roasters find value in comparing the difference between
+measurements on different data series. For example, the difference between
+intake and exhaust air or the difference between air and seed temperatures.
+These can be expressed as an additional relative temperature series. Similarly,
+a roaster might have multiple thermocouples where neither is individually as
+reliable as taking the mean between the two. The difference and mean series
+allow either of these to be calculated automatically.
+
+Since these are very similar structurally, a common base class is provided
+for performing some calculation based on two inputs. Difference and mean
+series then only need to override the |calculate()| method.

+@** Another Approach for Modbus RTU Support.
+
+\noindent The original code for dealing with Modbus RTU devices had a number of
+limitations. It was awkward to configure, limited to using a single device per
+bus, supported a small number of channels, and only worked with fixed point
+numeric representations. The following sections are an initial draft of a more
+flexible reworking of Modbus RTU support which should be easier to extend to
+cover Modbus TCP, allows a wider range of numeric representations, and allows
+for the use of any number of devices on the bus and any number of channels.
+
+Initial support is focused on function 3 and 4 registers with a known
+configuration. Outputs and the ability to configure inputs based on the values
+at other addresses will be added later. Modbus TCP support is also planned.
+
+Once feature parity with the old Modbus code is reached, the older code will be
+removed.
+
+Rather than use a single configuration widget for the entire bus, this is now
+split to use one configuration widget for the bus and another widget for an
+input channel.

+@** Simple Plugins.
+
+\noindent The original motivation for this feature is to provide a simple way
+to allow importing data from other data logging applications. The problem is
+that there are huge differences in the data formats exported by different
+applications, sometimes there are differences that depend on how the other
+application was configured which cannot be reliably determined in an automated
+fashion, and if a substantial number of import plugins were created, any given
+person using Typica would be unlikely to ever use most of them.
+
+Based on these concerns, I wanted something that would make it easy to create
+new import plugins without the need to create a new build of Typica every time,
+I wanted it to be relatively easy for people to modify example import plugins
+to suit the data they wanted to import, and I wanted it to be easy for people
+to hide plugins that they were not required.
+
+This is handled in a way similar to reports. A new directory is provided with
+the \pn{} configuration which contains files with script code. A menu item is
+available that will examine the files in that folder to populate its sub-menu.
+
+@<Process plugin item@>=
+QMenu *pluginMenu = new QMenu(menu);
+if(itemElement.hasAttribute("id"))

+@* Saved Printers.
+
+\noindent In most cases it's best to handle printing in a way that is common
+across many applications. Put a Print menu option in a File menu, bring up the
+platform's standard print dialog, and allow people to take full advantage of
+the flexibility this provides.
+
+In more specialized use cases, however, it may make more sense to provide
+faster access to a printer that might not be the default printer for that
+computer. The first use in Typica where this makes sense is in printing tags
+that can follow the coffee and uniquely identify that batch. Using a full sheet
+of paper for this might be excessive and time consuming. Instead, it might make
+sense to get a small, inexpensive thermal receipt printer to keep at the
+roaster. If this were not the default printer, it would quickly become tedious
+to bring up the print dialog and change the selected printer after every batch.
+
+In cases like this, it would be better to provide a combo box in the window
+where a printer can be selected and remembered as the default printer just for
+that particular use, and allowing people to print directly to that printer
+without going through extra steps.

+@** Threshold Annotations.
+
+\noindent Value annotations are fine for cases where we want to capture the
+fact that a control series has changed to some specific value, but there are
+times when it is more useful to know when a data series has passed through some
+value in a particular direction even if the exact value of interest is never
+directly recorded. For example, it would be possible to automatically mark a
+point near turnaround by watching for a rate of temperature change ascending
+through 0. This could also be set up to match range timers and mark events of
+interest that begin at consistent temperatures.
+
+As usual, this is a feature that must be configured on a per roaster basis.

 @* Scripting QWidget.
 
 \noindent The first interesting class in this hierarchy is |QWidget|. This is
 Version 1.6 adds a new property for handling the |windowModified| property
 such that an appropriate prompt is provided to confirm or cancel close events.
 
+Version 1.8 adds a new |setupFinished()| slot which is called after the
+initial |show()| at the end of window creation. This emits a |windowReady()|
+signal. Scripts can connect to this signal to perform tasks that must happen
+after the window has fully finished opening. The initial use for this is
+validating that all required configuration has been performed for a given
+window to be useful and, if not, immediately closing that. Without this, a
+call to |close()| in the script is reversed when the function creating the
+window calls |show()|.

-@* Timers.
-
-\noindent While some devices will output a steady stream of measurements which
-can be continuously read as they come in, other devices must be polled for
-their current state. One approach is to poll the device immediately after
-reading the response from the previous polling, but there are times when we may
-want to limit the rate at which we poll the device. There are also devices
-which specify a length of time during which data should not be sent. For these
-cases, we expose |QTimer| to the host environment which allows us to wait. This
-is also useful for producing simulations to test features without needing to be
-connected to real hardware.

+@** Typica User Management.
+
+\noindent Starting in version 1.8, the concepts of database user and \pn{} user
+are separated. This means that there must be controls for creating new users
+and for selecting the user to log in as. Other management interfaces can be
+implemented in configuration scripts.
+
+@* Application extensions for user handling.
+
+\noindent In order to present information about the currently logged in user
+globally, it was decided to provide a few methods in |Application| that can be
+used to report and change the current user.
+
+The first of these simply reports the currently logged in user.
+
+@<Application Implementation@>=
+QString Application::currentTypicaUser()
+{
+	return currentUser;
+}
+
+@ Next is a method that can be used to force the login of a specified user
+without checking for an entered password. This is used for users that are set
+to login automatically.
+
+@<Application Implementation@>=
+void Application::setCurrentTypicaUser(const QString &user)
+{
+	currentUser = user;
+	emit userChanged(currentUser);

+user name and password specified and reports if the login attempt was
+successful.

+	dbquery->bindValue(":name", user);
+	dbquery->bindValue(":password", password);
+	dbquery->exec();
+	if(dbquery->next())
+	{
+		currentUser = user;
+		emit userChanged(currentUser);
+		return true;
+	}
+	return false;
+}
+
+@ A convenience method is also provided to attempt an automatic login if one is
+specified in the database.
+
+@<Application Implementation@>=
