  Note: there is an option on the Synchrony configuration page to restore the pre-H smoothing method

• Added option to copy local clients to a remote client location
  (If the remote client location in data paths was NOT there at start of EEGer, it resets itself
  to point to local folders and tells you it did that so you can continue. This option in Archive/File Management
  lets you copy those local sessions back to the remote location when it gets reconnected.)

  Note: These devices only function in EEGer when using 24-bit mode until further changes are made

  Note: Also added an informational error message if something incorrect happens since nobody else has reported the crashing situation

• Alpha/Theta logic corrected (bell reward was never given) (#403)

• Added message about no 2^nd monitor when expected (#389)

• Revised keyblock installation to install no matter where the keyblock is located on double click

• Added option to mazes to allow random order of mazes (#391)

• Added serial port information display to help options for tech support

• Added display of reward direction in review if not normal Rwrd mode (#400)

• Made Game Initialization Tool and Tailor Games menu buttons taller so not hidden behind toolbar
  (which you were supposed to set to autohide anyway but Windoze sometimes forces it up)

• Added new averaged Psync functions for 4-channel work – still in experimental stage

• Added RED message in Amplifier/Encoder test if the serial port configured in EEGer is not the port being used for the test (since the test program may use a different port).
  
  

Note: Once again, documentation is behind schedule since the fixes needed to be available sooner than scheduled. No really significant changes were necessary in the documentation. The majority of changes were made to enhance supportability.

Release Notes for EEGer4 version 4.3.0f (7June2013)

Changes made are:

• Added informational message for remote users if Select Client attempted without a flash drive installed.

• Minor message change for “Games Differ” message – tell user to rerun the Game Initialization Tool.

• Fixed logic for zero thresholds on reward channels (and rewardable status displaying on raw traces)(#382)
  Note that setting 0 threshold on any filtered trace makes its label show in BLUE meaning monitored-only

• Added average psync modes for 4-channel experiments (#372)

• Added multiple Psync modes (#370)

  
  Note: Documentation is slightly behind times due to forthcoming changes relating to peripheral measures.
  
  

Release Notes for EEGer4 version 4.3.0e (21May2013)

More issues discovered and resolved in this update. Corrected issues are:

• Corrected bug made in 430d which made inhibits be ignored under certain conditions
  This is considered a FATAL bug in 430d

• Fixed minor problem in exporting summary data

• Changed installer to require UNPLUGGING certain amplifiers during installation
  I think this is why the esiPro sometimes didn't work after a reinstall of EEGer

Release Notes for EEGer4 version 4.3.0d (15May2013)

More issues discovered and resolved in this update. Corrected issues are:

• Addition of several feedback modes requested at NIC (two Psync rewards, SUM/DIFF additions,etc.)

• Fixed possible J&J bug from 2011 due to renaming of IOtest to EIOtest
  Apparently, nobody noticed

• Fixed issue with multiple advanced rewards in same feedback mode (i.e. 2 Psync rewards, etc.)

• Fixed problem of not always starting in the correct feedback mode when changing layouts

Release Notes for EEGer4 version 4.3.0c (4May2013)

Several issues were discovered in the first wide release of EEGer4 4.3.0b. Corrected in this update are:

• Inclusion of DirectX library file needed for some versions of Windows depending on Windows update paths
  Apparently, this file needed depending on when DirectX updates were made. Not needed in W7/W8 or later factory versions of XP

• Change to smoothing factors logic for the Iris game (and allowing tailoring of initial values)

• Allow remote flash drives up to 64 GB in size

• New background image forced in
  This overrides any user setting at installation time

• Incorrect overwriting of default color set and font selections was removed

• Renamed ProComp to ProSB as an input source

• Problem with some games not displaying (if Iris game was installed)
  Issue was a limited-size internal buffer used to unpack game data. Changed to dynamically size buffer.

• Problem with WayForward games not running (Space Race, EEG Chomper, Boat Race)
  A change to support Windows 8 made 2-computer versions of 3D games NOT have correct address to monitor.
  Fixed by using a nonsense value instead of the W8 value.

Release Notes for EEGer version 4.3.0b (9April2013)

EEGer4 version 4.3 is a highly modified and updated version of the older EEGer 4.2 neurofeedback software. As part of the development process, there has been an extended test process carried out to verify operation of all components of the software. Titles were restructured to be more explanatory and rearranged into more logical arrangements.

Significant changes in EEGer4 are:

• Optional support for 4 channels of EEG

• Up to 3 displays of peripheral data on client feedback displays
  (but not fully supported by all amplifier/encoders/interfaces)

• Major revisions to zscore integration

• Extended controls/feedback modes to support ANI zscore computations

• Correction of all known bugs in EEGer 4.2.2p

• A new optional feedback display (Iris) to support multiple reward/zscore values

• Revised documentation (compliant with IEEE Std 2010-2012
  IEEE Recommended Practice for Neurofeedback Systems)

• Inclusion of more utility programs in base release

• Multiple customizable session plans and ability to assign to existing clients

• Updated storage formats for additional data
  (Note: EEGer4 can read all earlier EEGer files but older EEGer software cannot read EEGer4 files)
  
  
  As part of the EEGer4 updates, provision for future modes and capabilities were made.

Support for EEGer4 is provided by EEG Education & Research Inc.
