Stable 8.2.0 Release (Mar 18 2026)

FreeSurfer version 8.2.0 can be found here. This is a minor release and will give the same output of recon-all when it is run in the same way. We have stopped supporting CentOS7 and have added support for Rocky 9 Linux, Ubuntu 24 Linux, and MacOS Tahoe (26.1). Note that different combinations of build and execution operating systems can give different results (see "Control of operating system" below).

• New features:
• Claustrum segmentation (mri_claustrum_seg)
• Pituitary and pineal glands segementation (mri_pglands_seg)
• Control of operating system when running recon-all. Create a file called fs-allowed-os.txt with the allowable operating systems. If recon-all is not run from one of these operating systems, then it will exit with error. See fs-check-os --help for how to use. This, along with FS build version specification (fs-allowed-versions.txt) can go along way towards assuring repeatability.
• fs-eddy and fs-topup frontend to run FSL eddy and topup corrections for diffusion analysis
• Bug fixes:
• Fixes xhemireg (cross-hemisphere surface registration);
• Fixes gtmseg (now creates segementation with sinus segmentation, arteries, vermis, pons)
• There was an occasional error in license reading when running mris_volmask that would cause recon-all to crash for no apparent reason when multiple threads were used.
