<font face="Calibri">Dear friends and colleagues<br>
<br>
We are happy to announce a new version of TrackMate, our Fiji
plugin for your everyday tracking problems. <br>
<br>
The full list of changes is listed here:

some highlights:<br>
<br>
Version 2.2.0 focuses mainly on extendability, tracking
performance and detection accuracy.<br>

LoG detector was not behaving as a true LoG detector,
which strongly hindered its accuracy and potence. The
problem is now fixed and<span

vastly improved</b>. You should now observe much better
results when using this detector: less spurious spots,
better spot size sensitivity, better sensitivity to faint
spots. On its side, the DoG detector now handles spots
that lie on the border of the images better. Of course,
the results will be different when comparing to v2.1.1.</font></big></big></li>

We are very grateful for the user feedback we received, and for the
courageous users that tested and reported problems during the RC
phase. We hope you find the tool useful. We hope you find the tool
