biosig v3.9.2 is available.
It comes improved support of several dataformats, and addresses a number
of known and potential vulnerabilities.
Find below a detailed list of improvements. Its definitively worth
upgrading.
The ABI has not changed, so in case of dynamic linking, you can just
replace libbiosig.so
and your are all set. In case of static linking, you need to recompile
your application.
As usual, downloads are available from here:

= Changes in v3.9.2
* Improved support of data formats:
- ABF1 && ABF2: several improvements:
some scaling issues were addressed
support for nOperationsMode=5 (Episodic Stimulation Mode) added
- FEF support improved;
Files from CNSystem's Taskmonitor can now be opened.
- XML-based formats:
disable use of internal copy of tinyxml, support for XML-based
formats
will depend on the host providing tinyxml at build-time
This avoids compilation errors on some platforms (Mac Ports?).
* Security-related improvement:
- MFER:
add guard against unintended and potentially unsafe use of MFER
In order to read MFER data, you need to set the environment
variable
set BIOSIG_MFER_TRUST_INPUT=1
* Debian bug #1112133 is now fixed. This addresses all

where not fixed then, these are fixed now. These changes address also
the vulnerability report TALOS-2025-2296 and a view similar issues.
* Platform support:
- New: Python 3.14
Enjoy. Merry Christmas and best Seasons greetings,
