# Star-Oddi HRT Analyzer changelog


## v 1.1.0 - Feature release: Annotate processed graph and Combined HRV file
* Performance improvements
* User annotations are now visible on both the raw ECG and the bandpass processed graphs.
* User can annotate directly on the bandpass processed graph.
* A new HRV file that combines the PC processed records with those User processed records that exist.
* Records that contain zero or one R-R interval are now included in the HRV file, with HRV set as -1.
* An HRV file was not created if a HAT file used a dot as decimal separator for the seconds.
* Analyzer will now warn the user if they attempt to load a HAT file that is missing the sampling frequency definition.

## v 1.0.5 - minor bugfixes
* Bug where user annotated data doesn't get written to the .HRV file is fixed
* Application generates a .CQI file for user annotated records in working folder when the 'save'-button is clicked
* The "Process single record"-button gets re-enabled if an error occurs in the filter process
* HRV calculations have precision of 0.01 ms

## v 1.0.4 - minor bugfixes
* Applcation uses the period (1/sampling frequency) from the most appropriate built-in filter to calculate the BPM and HRV (user) if the record has not been processed. If the record has been processed, the period from the used filter is used.
* The built-in filters dropdown shows only the appropriate filters for the currently loaded record i.e. HRT filters for HRT records and HRT-ACT filters for HRT-ACT records
* Application highlights the built-in filter in the built-in filters dropdown that has the same sampling frequency as the currently loaded record.
* Application shows a warning message if a filter is selected whose sampling frequency does not match the sampling frequency of the record.
* Application can read .HAT and .DAT files where the date and time are separated by a tab.
* Application works with a reconverted .DAT file where points have been removed.
* If an error occurs while reading a .DAT file, the Analyzer continues without the data from that .DAT file. An error message is displayed saying that a .DAT file was found but could not be interpreted
* ECG graph shows correct values when the x-axis is set to Time[ms].
* Analyzer shows a loading indicator and counter when record IDs are being read from the selected .HAT file and put into the ID dropdown. This process was also made faster.
* The "Data saved to enhanced .DAT in working folder" text when the "save to enhanced .DAT" buttons are clicked does not disappear until a new record is loaded.
* The "built in filters" dropdown shows only the filters appropriate for the logger type of the currently loaded record e.g. if a MHL record is loaded, the dropdown only contains MHL filters.
* The "built in filters" dropdown shows the names of the filters rather than their file names.

## v 1.0.1 - minor bugfixes:
* Installer defaults to a directory that works.
* Better internal handling of ECG records.
* Application stops the user from selecting data folders inside the application folder (for it will be erased when uninstalling).
