-@** Changes from Version 1{\char`.}4.
-
-\noindent An improper conversion bug when viewing data in Celsius has been
-corrected.
-
-Modbus RTU device configurations in which no configuration information was
-requested from the device at setup time previously did not collect any
-measurements. This has been fixed.
-
-The script binding for |QTime| now features the {\tt valueOf()} method. This is
-called implicitly when comparing two time values and allows the results of such
-comparisons to be as one might expect.
-
-The script binding for SqlComboBox now supports |findText()|.
-
-@** Changes from Version 1{\char`.}3.
-
-\noindent The {\tt CalendarPopupEdit}, {\tt CoffeeOrderForm}, and
-{\tt CoffeeItemPurchaseEditor} classes have been removed.
-
-Data exported in CSV now depends on the current view granularity.
-
-Derived data series by linear spline interpolation now supported.
-
-Both NI DAQmx Base and NI DAQmx are now supported in the same build along
-with all other new hardware support.
-
-Changes have been made to improve support for collecting measurements from
-multiple devices.
-
-The |GraphView| now supports roast profile translation. A new class has been
-added to support this feature.
-
-The new {\tt -c} command line argument allows the load configuration prompt
-to be bypassed.
-
-Support for reports loaded into a menu dynamically and for presenting reports
-in a menu hierarchy.
-
-The ZoomLog should no longer be editable.
-
-Basic use of |QWebView| has been added. This has been used to enable printing
-roast profiles and allows for a larger range of reports than is possible with
-the reporting framework used previously. The old reporting framework is still
-available for compatability with old configurations, however that code is now
-considered to be depreciated.
-
-The |ZoomLog| is now capable of dispaying temperature measurements in various
-units.
-
-Ambiguity in library bindings has been eliminated to improve reliability of
-Windows builds.
-
-Minor changes to improve coding style consistency.
-
-|QIODevice| has been extended for simpler use with classes that expect string
-data.
-
-New convenience properties have been added to the |QDateEdit| script binding.
-
-Database error reporting has been improved.
-
-The {\tt <stretch>} element can now be used in horizontal and vertical layouts.
-This can be used to change the distribution of excess space in a layout in ways
-that look better than the default handling.
-
-The |MeasurementTimeOffset| filter now works correctly when midnight occurs
-during a batch.
-
-The |openEntryRow| signal has been added to |SqlQueryView|. This can be used in
-situations where it is not convenient to have a unique identifier in the first
-column of the view. An invokable |data()| method was also added to this class.
-
-Preliminary support for Modbus RTU devices has been added.
-
-A new device and logging window configuration system has been introduced which
-allows people to edit their device configuration graphically instead of needing
-to create new configuration XML documents for the most common types of
-configuration change.
-
-Table views expecting numeric data now support entering arithmetical
-expressions for evaluation.
-
-@** Changes from Version 1{\char`.}2.
-
-\noindent A vast number of changes have been made to the source code since
-version 1.2.
-
-@* New Reporting Framework.
-
-\noindent A new reporting framework has been added to \pn{}, greatly simplifying
-the creation of reports. See the Reporting section for full details.
-
-@* New Classes.
-
-\noindent The |AnnotationSpinBox| class has been introduced. This allows manual
-entry of numerical annotations. The use of this class is not recommended as it
-would almost certainly be better to have this information logged automatically.
-The class is provided for situations in which this is prohibitively expensive.
-
-The |FormArray| class has been introduced. This class makes it easy to create
-user interface elements consisting of an arbitrary number of duplicated forms.
-This depreciates the {\tt CoffeeOrderForm} and {\tt CoffeeItemPurchaseEditor}
-classes.
-
-A proxy class named |SqlQueryConnection| has been added. This wraps |QSqlQuery|
-and manages its own |QSqlDatabase| connection. The |invalidate()| property has
-been added to query objects in the host environment in order to correct database
-connection leaks.
-
-Horizontal and vertical scale widgets have been added to improve the user
-experience when filling out cupping forms.
-
-@* Modified Classes.
-
-\noindent The |XMLOutput|, |XMLInput|, |CSVOutput|, and |ZoomLog| classes have
-been modified along with the XML format used by \pn{} to support saving and
-restoring multiple data series in a single file.
-
-Inserting measurements into a model has been optimized for the most common use.
-A large reduction in CPU utilization from \pn{} should be observed.
-
-@* New Configuration Options.
-
-\noindent Several additional methods have been added to the host environment for
-working with tables created by {\tt <sqltablearray>} elements. The |data()| and
-|setData()| methods can be used for examining and manipulating data in table
-cells. The |quotedColumnArray()| method can be used to obtain arrays suitable
-for insertion in {\tt text[]} fields of a database. The |bindableColumnArray()|
-and |bindableQuotedColumnArray()| methods produce values appropriate for binding
-to query placeholders.
-
-The |sqlToArray()| method has been modified to strip quote characters from the
-start and end of each array element if that element is quoted.
-
-It is now possible to change the application default fonts from the host
-environment.
-
-There are new layout options available. Grid layouts and stacked layouts are now
-available. It is also possible to assign an ID to any layout for manipulation
-from script code.
-
-It is now possible to specify that a combo box should be editable without adding
-script code.
-
-It is now possible to apply validators to line edits through configuration
-element attributes. Numeric, integer, and regular expression validators are
-supported.
-
-Support for Qt stylesheets has been added. Please use this sparingly.
-
-|QXmlStreamWriter| and |QXmlStreamReader| can now be used from within the host
-environment.
-
-@* New Versions of Qt.
-
-\noindent \pn{} has been linked against Qt 4.6.2 and is tested as working on Mac
-OS X 10.6.
-
-@* Bug fixes.
-
-\noindent A change in the |Application| class eliminates a problem with
-segmentation faults in the Linux build.
-
-@** Changes from Version 1{\char`.}1.
-
-\noindent The code has been tested when linked against NI-DAQmxBase 3.2 for use
-with a NI USB-9162 Hi-Speed USB Carrier. No code changes were required and no
-text appears on the console.
-
-NI-DAQmxBase is linked at run time rather than compile time. Also, nidaqmxbase.h
-is no longer required.
-
-It is now possible to inspect a |Measurement| object to determine the unit used
-for the measurement or create a new |Measurement| converted to a different unit.
-
-Recent versions of Qt have corrected bugs in the graphics view architecture.
-This has allowed some of the kludges of previous versions to be removed. The use
-of Qt 4.4.3 is now recommended.
-
-The configuration system has been changed significantly. The preferred method of
-describing the user interface is with an XML description with application data
-flow still defined through script fragments. Most configurations from version
-1.1 should continue to work when wrapped in {\tt <application><program>} XML
-elements, however the new configuration system makes it easier to produce far
-more complex and featureful configurations. Work on this portion of the code is
-not complete and requires additional documentation which is beyond the scope of
-the source code documentation.
-
-Several new classes have been added to the host environment.
-
-The |Application| class now manages a connection to a PostgreSQL database which
-other classes and the host environment can use to interact with a database.
-
-The {\tt RoastControlWindow} class used in version 1.0 and depreciated in
-version 1.1 has been removed.
-
-@* Bug fixes.
-
-\noindent The |GraphView| class now scales the graph to fit the viewport when
-the widget is resized. This was not the case prior to version 1.1.3.
-
-@** Changes from Version 1{\char`.}0.
-
-\noindent The most substantial change from \pn{} version 1.0 is the introduction
-of an ECMA-262 host environment intended for setting up the user interface and
-program data flow. The old {\tt RoastControlWindow} class was depreciated.
-
-This host environment provides access to most of the classes in \pn{} and a
-selection of classes from Qt. These classes can be used in scripts to the extent
-needed to prevent feature regressions. The example scripts provided should work,
-however attempts to go beyond what is provided by these examples may require
-modification to the source code.
-
-@* Bug fixes.
-
-\noindent The |TimerDisplay| class had a bug that would cause three error
-messages to appear on the console for every |TimerDisplay| object instantiated.
-This bug was fixed in version 1.0.6.
-
-When the user interface and data flow was hard coded, other parts of the program
-could make assumptions that are not necessarily true in different configurations
-without being detected. Moving from a configuration with one channel on the DAQ
-to a configuration with two revealed faulty assumptions in two classes.
-
-The |DAQImplementation| class used a constant 1 instead of the number of
-channels to specify the size of the measurement buffer. The result of this was
-that no measurements would be generated when more than one channel was set up.
-This bug was fixed in version 1.0.7.
-
-The |XMLOutput| class failed to handle rows with no value in the temperature
-column for rows with values in any column after the temperature column. Such
-rows were never produced in version 1.0 but can be produced now. Such rows were
-frequently produced during development. This bug was fixed in version 1.0.8.
