Enhancements:

1. 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++
   • 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),
2. 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,
3. 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,
4. Documentation:
   • Additional "Multi-Elements" Demos in "Demos, Examples & Tutorials 1RC5".

Requirements:

• G4 or better, Mac OS X 10.4 or later, QuickTime 7.1 or later, 32 MB VRAM or more.
