[jdtournier]

We are pleased to announce the immediate release of MRtrix 3.0.1.

This is primarily a bug fix release. We recommend users upgrade as soon as practical, using the instructions provided on our downloads pages (for precompiled packages), or the usual procedure for installations from source.

The full changelog is attached below. Noteworthy changes include:

• fix issue in fixelcfestats when importing data
• fix issue in dwifslpreproc that prevented the gradient table from being properly updated
• fix compatibility issue with FreeSurfer 7 lookup table in labelconvert
• installation instructions for precompiled packages on Windows via MSYS2 have changed

All the best from the MRtrix3 team!
