Version 3.2.0, 3 March 2022

• Allow user to specify which port(s) to read data from in Advanced dialog

Version 3.0.6, 1 April 2022

• Fixed bug with FilePerChannel digital ins/outs not being indexed correctly.
• Increase max number of columns to 16.

Version 3.0.5, 3 February 2022

• Removed unused Context Help buttons from dialogs.
• Reduced latency of spike .dat file writing so that these files are updated as soon as spikes are detected.
• Added option to start software without OpenCL.
• Improved TCP parsing to handle unexpected whitespace in a string of commands.
• Added WriteToDiskLatency setting for users to control.
• Added CreateNewDirectory setting for users to control.
• Fixed displaying 'save to disk' icon for enabled non-amplifier signals (e.g., aux in, digital in, analog in).
• Fixed small memory leak during TCP data streaming.
• Altered 'Rescan Ports' behavior so that if the system went from no headstages to at least one detected, the displayed port will update to the present chip(s).
• Added drag'n'drop option for various settings files.
• Added more descriptive error messages when a Probe Map file is loaded as a general settings file.

Version 3.0.4, 5 August 2021

• Fixed small memory leak that occurred when saving in the File Per Signal Type file format.
• Improved XML settings file parsing so that files that don't include any headstage channels can still be correctly loaded.
• Minor improvement to make error logging more detailed and efficient.
• Modify episodic triggered recording algorithm to ignore brief trigger-off events.
• Improved optimum SPI delay finding algorithm so that setting delay manually is less likely to be necessary.
• In data file playback mode, electrode impedances are now displayed.
• Fixed issue with external fast settling in RHD systems not properly triggering as a result of digital input activity

Version 3.0.3, 15 April 2021

• Added 50 ms option to PSTH pre-trigger and post-trigger spans.
• In "One File Per Signal Type" data file format, added option to save auxiliary inputs (e.g., acccelerometer data) in amplifier.dat file.
• Fixed bug that sometimes causes crashing when PC audio was enabled.
• Fixed bug that did not display auxiliary inputs or supply voltages from second headstage when dual headstage adapter was used.
• Expanded OpenCL compatibility to fix problems with OpenCL initialization on some systems.
