Browse buttons for file access now check whether the file is supposed to exist and open an appropriate dialog. Closes #504

Wildcards are now allowed in file extensions. Use a ? to match a single character, [0-9] to match a number, [a-z] to match any letter and * to match anything. Re #406

Added a method to create a bare pointer, i.e. one that is not wrapped in a boost shared_ptr. I need this for the specialized algorithm GUIs since the Qt pointers don't seem to like being wrapped. Re #444

Add test for CalculateTransmission. Also replace some dodgy hard-coding in the algorithm itself. Re #375.

Altered ConfigService so that relative path names are converted to absolute ones. Note that the original value is not actually altered but the call for a key is intercepted and a locally stored value is returned. Re #404

Modify buildserver script to report that tests failed if there is a crash (n.b. this change also means that it will report a failure if a test includes output containing a linefeed). Also fixed FileValidatorTest. Re #279.

Move LibraryManagerTest again because it implicitly depends on DataObjects (because of the contents of UserAlgorithms). Other updates for compiling in Eclipse as separate packages instead of into one big library. Re #100.

Spotted inconsistency in declaration of NeXus namespace. Plus some other tidying up for doxygen. Re #100.

re #185. All algorithm parameters now have direction: Input, Output, or InOut. Output parameters (except workspaces) are not shown in the ExecuteAlgorithm dialog box in QtiPlot.

Added a couple of tests for new Property method. Also corrected a bug with isDefault flag for Workspace properties. Re #179.

Moved Alogrithm::fillHistory a little closer to the "path of object-oriented righteousness", as one of my programming teachers would say. Also removed duplicate of methods resulting from Python integration. Re #179.

UnitFactory now only creates a single instance of each unit and hands out a pointer to that instance each time the unit is requested. Re #153.

Added file validator for properties. Also added a method for getting the type of the validator as a string - could not see an alternative way of doing this. Refs #154

Added an allowedValues override to WorkspaceProperty, which returns the current contents of the ADS. Changed return type of allowedValues to vector (was set). Modified WorkspaceProperty::isValid so that it fetches output workspaces if they already exist in the ADS. Re #150.

Added a ListValidator, which allows a (string type) property to be restricted to a set of values. Changed the "Target" property on ConvertUnits to use this. The Property class now has an allowedValues method which returns the set of allowed values if a ListValidator is attached to the property, or an empty set otherwise.
Also modifies the PropertyWithValue class so that it is no longer possible to set a property's value to an invalid value.
Re #150.

Added a new Axis class which holds the spectrum numbers and the unit. An axis can also be of numeric type and the case where the axis (X) values can differ across histograms in a 2D workspace is handled by the new RefAxis class. Re #135.

FilterChannel added to the logging to allow filtering of individual logging channels based on a priority level.

This allows you to send debug messages to the log while only sending information level messages and above to the console.

added missing DLLExport

Adjusted runtest.bat script to work if started from a VS command prompt and added include path to project include directory
