New Features:

• Support for limited-lifetime in Multi-Element Field (MEF),
• Support for element specific rotation as function its position in Multi-Element Field (MEF),
• Support for dot specific speed and direction in Random-Dot Kinematogram (RDK),
• OpenGL preview and export to movie for Multi-Element stimuli (RDK & MEF) and Dynamic Composing,
• Addition of 'za' output in Custom Stimuli to specify stimulus transparency,
• BETA support for "Mono++" and "Color++" modes provided by CRS Bits++ (please send feedback!),
• Support for onset trigger from composing stimuli in Dynamic Composing (except for fused mode),
• Support for absolute and relative step size in Adjustment procedure,
• Support for multiple step sizes in Adjustment procedure,
• Support for Keypad input devices (Adesso keypad AKP-150, Targus Keypad PAUK10C),
• Support for stereoscopic stimuli (monocular, binocular and dichoptic presentation) in vertically split display setup (free-fusing, mirror-based stereoscope, or dual video input goggles),
• Support for Scaling Factor in Rendering properties (Control Settings Palette),

Feature Improvements:

• Addition of [$] variable format to specify the latest value set for a random variable (useful for random variables used in different events),
• Support for expression operands in range format (:),
• Support for expression-based values for minimum and maximum levels in Method of Constant Stimuli, mean and range of initial value for Staircase and Adjustment,
• Support for interleaved adjustments,
• Support for randomly ordered interleaved methods and adjustment procedure,
• Support for multiple values (separated by comma) associated with the same event in Association Composing,
• Faster generation of dynamic grating-like, checkerboard-like and custom stimuli,
• Better error detection when using Wizard,

User interface improvements:

• Change in selection of event subcategory is now prevented by default, but can be forced by pressing simultaneously the Control key,
• Automatic expanding of experiment hierarchy after run-time errors occurs,

Fixed:

• Problem with duplicated columns in results data table,
• Failing Gamma correction,
• NetStation crash at closing time,
• 'Keep As Fixation' option not always working for Shape stimuli,
• Fixation mark overlapping bug in first trial after text stimulus,
• Changes in stimulus duration not being saved,
• Crash occurring with variable-based duration in Visual stimuli,
• Problem with manual entries of Gamma readings not being validated except when using a keypad,
• Problem with duplicate estimates provided by the adjustment method in Root data level (Plotter panel),
• Problem with use of conditional variables in decision for Discrimination and Yes/No procedures,
• Selection problem in Conditions method,
• Problem with results report for interleaved Bayesian and Constant Stimuli methods in Root data level (Plotter panel),
• Run-time error when creating experiment with Wizard,
• Crash with Japanese language,
• Run-time error when no EDID information available for old CRT display,
• Stimulus glitch when specifying log sampling in Bayesian method,
• Problem with non-sticking default properties for Multi-Element Stimuli (RDK and MEF),
• Default input device now properly selected when no other device has been explicitly defined,
• Serial device missing from the trigger pop-up menu in control settings palette,
• Bug with editable data folder in 'Session Information' panel which could lead to data loss for the current session,
• Cosmetic bug in Control Settings for MEF/RDK stimuli,
• Stimuli preview now uses the display settings from experiment event if available (Display preferences otherwise),
• Crash with selection of modulation mode other than contrast,
• Problem with contrast not being used when creating preview of statically composed stimuli,
• Bug with Src and Dst Mode not being disabled except for Custom mode in rendering control settings,
• Bug preventing stimuli editing when using expressions in some formats,
• Error reported when using dependent variable in time-varying expression,
• Apparent computer freeze due to too large generated stimuli (validity of geometry calibration now checked based on FOV range before running the experiment),
• Issues with validation of pending text field entries in Control Settings Palette,
• Graph sampling problems for fitted data in Plotter panel,
