Hi Troels, I've mentioned this a couple of times: http://article.gmane.org/gmane.science.nmr.relax.devel/6491 http://thread.gmane.org/gmane.science.nmr.relax.scm/22089/focus=6504 But, as this is your masterpiece, I'll let you choose how it is released to the relax user community. Would you prefer to have the disp_spin_speed branch code released as relax 3.2.4 by itself? Or would you prefer to include it with the specific API changes of the zooming_grid_search branch which require the minor version number incremented, so this will be relax 3.3.0? Note that because of the zooming_grid_search changes, scripts for relax <= 3.2.x will not be compatible with relax >= 3.3.0. I will also complete the zooming_grid_search branch soon, and maybe release relax 3.3.0 before the end of next week (unless there are complications and the release will be in the second half of August as I'll be on holiday). Cheers, Edward
