    Release Notes: This release adds a filter to the annotations list. The BI9800 to EDF converter has been modified to make it work with 48-hour recordings. The viewtime (fileposition) indicator is configurable. The date has been added to the viewtime indicator in the left down corner of the screen. The window title bar is configurable. A bug has been fixed in the EDF+D to EDF+C converter. This release adds the ability to save and load different color schemas. It adds support for the Unisens file format. It adds the ability to save and load color schemas.

      Release Notes: This release added an SCP-ECG file to EDF+ converter, two shortcuts (Plus and Minus keys) that increase or decrease the amplitude of the signals (sensitivity), the ability to choose between little endian or big endian encoding in the binary/raw to EDF converter tool, and the ability to use aliases for the signal labels on the screen. The number of pre-defined montage shortcuts was created from 8 to 12 (keys F1 to F12). Qt has been updated to 4.8.5.

        Release Notes: This release adds a Manscan MICROAMPS binary file to the EDF+ converter. It solves another bug in the sorting algorithm used for the annotation list.

          Release Notes: This release fixes a bug in the ECG heartrate detection algorithm when a high samplerate was used, improves the sorting algorithm used for the annotationlist (it was very slow when the annotationlist contained more than 10,000 annotations), and adds the ability to adjust the samplerate divider for all signals at once in the reducer/decimator tool. EDFbrowser now checks for a newer version during startup. (This can be switched off in the settings menu.)

            Release Notes: This release adds a binary/raw to EDF converter tool. It solves a bug in the "Import annotations" tool. When importing from ASCII, incorrect onset times were created when there were more than 7 digits after the decimal point. A scrollbar has been added to the options/settings dialog in order to make it fit on screens with low vertical height (modern laptops with 16:9 screens). GTK-style support has been removed because it's broken. Qt has been updated to 4.8.4.

              Release Notes: This release adds sub-second precision for annotations when using the Nihon Kohden converter (before, the onset times of the annotations were rounded to seconds.) It adds Z-EEG measurement. It improves the header editor/fixer. It accepts files with a maximum of 2048 signals (before, it was limited to files with a maximum of 256 signals.) It can also fix the digital minimum/maximum fields in the header (e.g. when a broken number was written instead of an integer number). Qt has been updated to 4.8.2.

                Release Notes: A bug that caused a crash when saving an EDF or BDF file after importing annotations was fixed. The "Export ECG RR-interval" tool was changed in such a way that you can easily export the whole recording. It is now also possible to import them as annotations directly. The "Import annotations/events" tool can now also import the duration of an annotation/event (from ASCII or XML files). The ability to hide or unhide annotations from the screen by right clicking them was added.

                  Release Notes: This release fixes a bug which caused a crash when the "Abort" button was clicked when opening a BDF file, fixes some other small bugs, adds some enhancements, and updates Qt to 4.8.1.

                    Release Notes: This release adds the ability to disable scanning for annotations or triggers when opening a file, depending on the filesize (this can be useful when working with big files which take a lot of time to read in annotations, events, or triggers), extends the capabilities of the header-editor (it can now also fix files which have a wrong number of datarecords written in the header or when the file does not end at the boundary of a datarecord; see the manual for the details), improves the ECG heartrate detection algorithm, and fixes some bugs related to signals with inversed polarity.

                      Release Notes: This release fixes a bug that caused the "print to PDF / Postscript / Image" to fail when non-ASCII characters were present in the new filename. It fixes a bug that caused "printing to image" drawing the signals too thick and incorrect rulers. It fixes a bug in the ECG heart rate detection algorithm that could cause wrong measurements whit high heart rates (more than 120 bpm). It adds Mousewheel zoom-in/out by pressing the Ctrl-key.
