Version 2.8.0 (2016-05-22)

Note: It is highly recommended to update to the latest version of LGS as it improves lighting performance
significantly. With the update, headset/mouse lighting no longer causes keyboard lighting to lag.

• HORIZONTAL COLOR WAVE EFFECT (HORIZONTAL RAINBOW)
  Added a horizontal color wave effect that can be toggled under the new color mode "Horizontal Gradient".
  The speed of the effect and the direction (left, right, center in and center out) can be set.
  The spacing between each column of colors can also be selected.
  
  
• VERTICAL COLOR WAVE EFFECT (VERTICAL RAINBOW)
  Added a vertical color wave effect that can be toggled.
  The speed of the effect and the direction (up or down) can be set.
  The spacing between each row of colors can also be selected.
  ARX Support for the horizontal and vertical color wave effects will be added in a future update.
  
  
• RECORDING DEVICES CAN NOW BE USED AS THE INPUT DEVICE
  Recording devices (such as microphones) can now be selected as the Input Device for the spectrogram.
  
  
• IMPROVED ERROR CATCHING FOR SPECTROGRAM
  Added better error catching and more helpful error messages for spectrogram errors.
  
  
• HEADSET/MOUSE LIGHTING REFRESH RATE INCREASED
  Headset/mouse lighting now refreshes at the same frequency as the keyboard lighting.
  
  
• BUG FIX
  Fixed an issue where the program would freeze if the refresh delay was set to a very low value when the
  On-Screen Output window was open.

Version 2.7.1 (2016-03-27)

• CONTROL SPECTROGRAM WITH MEDIA KEYS GLOBALLY
  The spectrogram can now be started and stopped using the media keys on your keyboard (Play/Pause and Stop).
  This feature now works even when the program is not in focus (eg. when in the background or minimised to tray).
  
  
• BUG FIX
  The status bar now works again.
  
  
• BUG FIX
  If an error occurs while loading settings at startup, the user will be given the option to:
  
  • Restore default settings and exit (a copy of the settings will be left in the settings folder).
    This will allow the program to start normally the next time it is started.
    
  • Do nothing and exit.

Version 2.7.0 (2016-03-20)

• REGIONAL KEYBOARD LAYOUTS
  Added an option to select keyboard layout.
  The available keyboard layouts are:
  Layout 1: United States (US), Chinese (CHT)
  Layout 2: International (INTL), German (DEU), Spanish (ESP), French (FRA), Italian (ITA), Nordic (NORDIC), Swedish (SW), Turkish (TUR), United Kingdom (UK)
  Layout 3: Japanese (JPN)
  Layout 4: Korean (KOR)
  Layout 5: Russian (RU)
  
  
• "EXTRA" REGIONAL KEYS NOW USED
  Spectrogram now uses the "extra" keys on regional keyboard layouts - be sure to select your keyboard layout in the settings.
  
  
• CONTROL SPECTROGRAM WITH MEDIA KEYS
  The spectrogram can now be started and stopped using the media keys on your keyboard (Play/Pause and Stop).
  Note that this currently only works when the program is in focus. However, it can be changed to work globally if there is enough demand for it.
  
  
• EASILY TRANSFER SETTINGS FROM PREVIOUS VERSIONS
  When updating to a new version of the program, the user will be able to seamlessly import saved settings from any previous version.
  This will make it much easier to transfer user settings over to a new version.
  
  
• AUTOMATIC UPDATE CHECKER
  The program automatically checks for updates on startup and displays an informative notification if an update is available.
  The user can also manually check for updates by clicking the button in the Settings tab. The update checker can be disabled if desired.
  
  
• HEADSET/MOUSE LIGHTING REFRESH RATE REDUCED
  Headset/mouse lighting now refreshes half as frequently as the keyboard lighting. While this is not ideal, this lighting was causing the keyboard
  lighting to be noticeably less fluid and in certain cases, appear extremely laggy. The delay itself appears to be happening within LGS.
  
  
• BUG FIX
  Fixed a bug where importing settings from version 2.5.0 and earlier would not work.
  
  
• BUG FIX
  Fixed a bug where the program would not start if there were two (or more) playback devices with the same name.

• The setting for Cycle Colors is now saved - if it was enabled, it will still be enabled when the program is started next time
• The ARX On-Screen Output now updates its colors correctly in the Cycle Colors mode

---

Version 2.6.0 (2016-02-28)

• Program has been renamed to "Logitech Spectrogram" to reflect widened device support (eg. mice and headsets)
• Logitech Mice and Headsets now pulse between the first and last selected Vertical Gradient colors when in that mode
• Added better error catching and more helpful error messages for startup errors

• Program now minimizes to the system tray
• Added an ARX Control App, allowing the spectrogram program to be controlled from your Android or iOS mobile or tablet devices
  This feature requires the "Logitech Arx Control" app to be installed on your mobile or tablet device
  Your device can also be used to display the on-screen spectrogram output
• Fixed a bug where the "Pause | Break" key was not being used by the spectrogram
