====================================================
--- Version: 3.9.1 ---------------------------------

Sun 24 Aug 2025
====================================================

It is mostly a bug fix release. The ABI did not change, so when using the dynamic linking,
only libbiosig.{so,dll,dylib} need to be replaced. In case of static linking,
please recompile your application.

The main features are:
- fixing several security issues
  TALOS-2025-{2231..2240} corresponding to
    CVE-2025-53518
    CVE-2025-53853
    CVE-2025-52581
    CVE-2025-54480-CVE-2025-54494
    CVE-2025-53557
    CVE-2025-46411
    CVE-2025-53511
    CVE-2025-52461
    CVE-2025-54462
    CVE-2025-48005
  Thanks to the CISCO-TALOS Team for their detailed reports.

- ISHNE format is now usable

- replace obsolete finite() with isfinite()
- improve build support for MACOSX on ARM
  (Thanks to Clemens Brunner for the patches)

- mex-files of biosig4octave (sumskipnan_mex and covm_mex)
  are now provided in proper directory
  (Thanks to Rafael Laboissière for the bug report)

====================================================
--- Version: 2.1.1 ---------------------------------

Sat 2 Jan 2021 18:15:45 CEST
====================================================

The main new features are:
*) Support for Python and R on Windows:
  a mechanism to load Biosig data into Python and R
  on the MS Windows platform. It consists of two parts:
  biosig2gdf.exe and loadgdf.{py,r}. biosig2gdf is an
  executable file that loads biosig data and converts
  it into a GDF data stream, this GDF data
  stream is then parsed by loadgdf.{py,r}.

*) biosig_vhdr_generator.sh ...
  ... is a tool to generate vhdr-header files for headerless
  binary *.dat files from a template header file.
  This can useful for data sets recorded with ktan
  and other recording systems. These header files
  can then be used to open the *.dat files with sigviewer
  and other biosig tools without additional conversion.
  The header information is provided through a
  vhdr template file.

*) some minor bug fixes.

=== Package: Biosig for Octave and Matlab ==========
--- Version: 3.4.0 ----------------------------------

Tue 21 Aug 2018 02:08:25 PM CEST
====================================================

* improvements in functions:
    detect_spikes_bursts
    roc

* remove some dependencies on NaN-toolbox in functions

* some documentation improved

* bug fixes (brainvision file format)



* mexSLOAD, mexSOPEN
  bug fix: remove undefined HDR.FILE object

* Autoconf is now used, and most configurations are done automatically
  - libtinyxml from operating system can be used
  - libcholmod is automatically used
  - enforces  -std=C99 or later
  and many more.

* Pagesize of initial read is increased from 512 to 4096 bytes

* gdf_time2tm_time:
	fix rounding issue.

* save2gdf, scp2aecg:
    anonymized processing can be controlled with command line arguments
    -a (yes) and -n (no anonymized processing)

* hdr->Patient.Name is now structured;
    it consists of  three fields, Lastname, Firstname(s), and Second lastname.
    The three fields are separated by the "unit separator" ASCII(31) or 0x1f;

    Data formats supporting structured patient names (e.g. SCP, HL7aECG,ISHNE,
    Persyst, etc, ) can make use of that structure. Other formats (e.g. GDF)
    can use the above encoding to store patient names in a structured way.

* JSON output
    reports not only PatientName but also Lastname, Firstname
    and secondLastname.

* scp2aecg, SCP->HL7aECG conversion
    - patient name is now structured in HL7
    - hospital information improved

  11073-10101a:2015a amendments to 11073-10101:2004
  has been updated.

    - A number of new definitions are added.
    - The following units were redefined, which might cause incompatibilities:

    65408 ->  6432,"B", "Bel", "relative power decibel"
     6816 ->  8096,"rpm","","revolutions per minute"
    65440 ->  8320,"dyne s m2 cm-5","Vascular Resistance Index"-...
    65504 ->  8192,"Wb m-2",,"<magnitude> Tesla"
    65504 ->  8192,"T",,"<magnitude> Tesla"
    65312 -> 10976,"mmHg s-1","rate of pressure change","millimeter mercury per second"
    65152 ->  8256,"V/s","","Volt per second"

    If you are concern, you might need to consider these changes
    on the application level.

--- Version: 0.59 ----------------------------------

Mon 17 Mar 2008 11:03:19 AM CET
====================================================

This is a major release:

- Support for reading additional fileformats:
    AINF, BrainVision, DEMG.
    Now, ca. 15 formats can be read, and 7 data formats
    can be written to.
  Several improvements and bug fixes are included.

Furthermore, biosig4c++ becomes more a library.
- It provides libbiosig.a with a clean
   external interface as defined in biosig.h.

This library is useful for several applications:
-  a mex-interface mexSLOAD for the use with Octave and
   Matlab is added. mexSLOAD seems somehow redundant to
   BioSig4OctMat; however mexSLOAD can read HL7aECG/FDA-XML
   data (this is not possible with BioSig4OctMat) and is
   typically much faster.
-  an interface to python is added. (this is still experimental)
-  The upcoming release of SigViewer will use it.

And finally,
- Apple platform is supported, too.

Mon 13 Oct 2003 08:02:10 PM CEST
======================================

BIOSIG  contains many useful functions for signal processing.
Many dataformats are supported, the toolbox provides a unique
interface to read many formats, writing of the most common
formats (EDF, etc) is also supported.

Several useful algorithm are implemented, e.g. QRS-detection,
algorithms for stochastic model paramters (autoregressive,
multivariate, time-varying etc.) are included through the
TSA toolbox. Handling of missing values and artifacts is
supported, assuming that NaN encodes artifacts and missing values.

Biosig contains the other toolboxes like TSA, NaN and Dataformats.


Changes:
