for future and past milestones.

DataLab Version 0.15.0

🎁 New installer for the stand-alone version on Windows:

• The stand-alone version on Windows is now distributed as an MSI installer (instead
  of an EXE installer)
• This avoids the false positive detection of the stand-alone version as a
  potential threat by some antivirus software
• The program will install files and shortcuts:
  • For current user, if the user has no administrator privileges
  • For all users, if the user has administrator privileges
  • Installation directory may be customized
• MSI installer allows to integrate DataLab's installation seemlessly in an
  organization's deployment system

💥 New features and enhancements:

• Added support for large text/CSV files:
  • Files over 1 GB (and with reasonable number of lines) can now be imported
    as signals or images without crashing the application or even slowing it down
  • The file is read by chunks and, for signals, the data is downsampled to a
    reasonable number of points for visualization
  • Large files are supported when opening a file (or dragging and dropping a file
    in the Signal Panel) and when importing a file in the Text Import Wizard
• Auto downsampling feature:
  • Added "Auto downsampling" feature to signal visualization settings (see "Settings"
    dialog box)
  • This feature allows to automatically downsample the signal data for visualization
    when the number of points is too high and would lead to a slow rendering
  • The downsampling factor is automatically computed based on the configured
    maximum number of points to display
  • This feature is enabled by default and may be disabled in the signal visualization
    settings
• CSV format handling:
  • Improved support for CSV files with a header row (column names)
  • Added support for CSV files with empty columns
• Open/save file error handling:
  • Error messages are now more explicit when opening or saving a file fails
  • Added a link to the folder containing the file in the error message
• Added "Plugins and I/O formats" page to the Installation and Configuration Viewer
  (see "Help" menu)
• Reset DataLab configuration:
  • In some cases, it may be useful to reset the DataLab configuration file to its
    default values (e.g. when the configuration file is corrupted)
  • Added new --reset command line option to remove the configuration folder
  • Added new "Reset DataLab" Start Menu shortcut to the Windows installer

🛠️ Bug fixes:

• Fixed Issue #64 - HDF5 browser does not show datasets with 1x1 size:
  • HDF5 datasets with a size of 1x1 were not shown in the HDF5 browser
  • Even if those datasets should not be considered as signals or images, they are now
    shown in the HDF5 browser (but not checkable, i.e. not importable as signals or images)
