 version 1.30      November 24, 2010
 ------------

 - Enhanced the "Export annotations/events" tool. Now you can choose the
   separator character (comma or tab) and you can choose different ISO
   time (and date) timestamps encodings. XML export is possible as well.

 - Solved a bug in de the "adjust filter" dialogue. When using a notchfilter,
   the "order" widget was shown instead of the "Q-factor" widget.

 version 1.29      November 9, 2010
 ------------

 - Added the possibility to adjust the filter settings while watching the result (realtime).

   of the signals automatically.

 ------------

 - Added support for reading the "Status" signal in Biosemi data files.
   This can be switched on/off in the settings menu.

 - Added a Biosemi to BDF+ converter.
   It converts the Biosemi trigger inputs to annotations which can be
   read and processed by EDFbrowser.

 - Added an EDF-converter for the Bmeye Nexfin / FrameInspector csv-output
   (beat-to-beat data, bloodpressure waveform, analog inputs).

 - Added zoom-in/zoom-out function using Ctrl++ and Ctrl--.

 - Added keyboard shortcuts and accelerators to the menu's.

 - From now on, the timescale will be saved in montages as well.

 - When opening a file, the last used montage (with that file) will be applied automatically.
   This behaviour can be switched off in the settingsmenu.



 version 1.27      September 27, 2010
 ------------

 - Made all the file-open/save dialogs native.
   This improves the speed in file-listing on some windows-pc's.

 ------------

 - Added an header-editor.

 - Added a file reducer/cropper.

 - Added the possibility to clip the signals to their pane.

 version 1.25      August 2, 2010
 ------------

 - Solved a bug that caused writing invalid files and/or caused to reject
   opening a file because of an incompatibility while in reality the file was valid.
   This was caused by a localizationproblem which occured only on systems where
   countrysettings are used that uses a comma as a decimal separator.

 - Changed the name of the "Display" menu to "Timescale".

 - Added the entry "3 cm/sec" to the the Timescale menu.

 - From now on EDFbrowser will use the DPI-settings from the underlying windowmanager
   in order to calibrate the screen. If this doesn't work well in your situation,
   you can still calibrate the screen manually in the settingsmenu.

 - Solved a bug that caused malformed waveforms when opening large files (>4 GB)
   and when navigating to the end of the file. This was caused by an integer overflow.

 - Solved a bug in the ASCII to EDF converter (couldn't open templates).

 - Changed the sourcecode to improve Mac compatibility.

 ------------

 ------------

 - Changed the DFT-algorithm of the powerspectrum to an FFT-algorithm
   in order to avoid long computation times.

 - Added an extra option to the Annotations export tool.
   Now you can choose to save the annotations in a comma separated
   textfile or in the EDFplus format.

 - Changed the position of the widgets in the annotation-editor window.
   The "Create" button will not be cut-off anymore when a monitor with
   a resolution of 1024 x 768 is used.

 ------------

   throug a file (PgUp,PgDn, etc,).

 - Added the possibility to use different backgroundcolors for different frequencyregions
   in the docked powerspectrum (colorbars).

 - Added an export function for the powerspectrum. This will export
   the data of the powerspectrum to a textfile.

 - Added a cursor to the powerspectrum.

 - Improved the way filters run-in.

 - Added an export function for annotations. This will export
   the annotations to a comma separated textfile.

 - Added a possibility to bind keys F1 ... F8 to predefined montages.
   This way you can quickly switch between different montages by
   pressing F1, F2, etc.

 - Removed a bug in the EDF+D to EDF+C converter that could cause a crash.

 - Removed a bug in the BDF+ to ASCII converter.


 version 1.21      may 11, 2010

   to compare different blocks of data and/or different signals).

 - Made a printing option for the Powerspectrum. you can print
   the Powerspectrum to a printer, Postscript, PDF or an image
   by rightclicking on the curve of the Powerspectrum.

 - The ASCII to EDF converter now has a multiplierfactor.
   Cleaned up the code of the converter as well.

 - Fixed a bug that caused writing to a freed memory area
   which could cause a crash when closing the program (mainly
   noticeable on windows).

 - Fixed a memoryleak.


 version 1.20      may 4, 2010
 ------------

 - Added a power spectrum analyzer (Discrete Fourier Transform).

 - Removed a bug that caused wrong vertical ruler values during printing.

   in the signalproperties dialog.


 version 1.19      april 20, 2010
 ------------

 - Added extra filter options: lowpass, highpass, notch, bandpass, bandstop,
   Butterworth, Chebyshev, Bessel, 1,2,3,...8 th order, adjustable bandpassripple
   or Q-factor.

 - Removed a bug in the BDF to EDF converter,
   clicking on "Select all signals" or "Deselect all signals"
   without a selected file, caused a crash.

 - Fixed a bug in the "Print to EDF" and "Print to BDF" function.
   Filter description in header was wrong (i.e. "LPF:" instead of "LP:").

 - Fixed a bug in the Filter Dialog. When adding a new filter when signals have
   different samplerates, initialisation of the new filter could happen with wrong
   samplerate, causing a wrong frequency of the filter.
