The latest release of AFNI is available now. Changes include
- thresholding of RGB datasets used as overlays
- you can change the titlebar label for a dataset, using the 'label2' field in the .HEAD file (set by 3drefit -label2) and setting the environment variable AFNI_TITLE_LABEL2 to YES
These are both from last night and this morning. I'm sure there are other things, but I can't recall them at this instant. I'm sure Ziad will chime in about SUMA. Oh yeah, we are working on some DTI stuff, but the first software (cf. 3dDTeig and 3dDWItoDTI) are just now available and not very sophisticated (yet). NIfTI-1 file support is in the works, but not yet fully actualized.

The version numbering system used in AFNI has changed. The old-style nice looking version numbers like '2.56f' are no more. The new-style ugly version numbers are something like 'AFNI_2004_12_21_1553', which encode the date and time of the code freeze for release. This is semi-automatically generated, rather than updated whenever it occured to me (not very often). Recall the AFNI motto: "All users are beta testers for life" (I'm sure it would sound more impressive in Latin). Now the version numbers will change more frequently, so you will become more aware of this perpetual flux in the code.
