→Description: Changed the bug tracker links in the description for better readability.
Note that this new 3.3 relax series breaks compatibility with old relax scripts. The important change, which is the main reason for starting the relax 3.3.x line, is the renaming of the calc, grid_search and minimise user functions to [http://www.nmr-relax.com/manual/minimise_calculate.html minimise.calculate], [http://www.nmr-relax.com/manual/minimise_grid_search.html minimise.grid_search] and [http://www.nmr-relax.com/manual/minimise_execute.html minimise.execute] respectively. Please update your scripts appropriately. A new relax feature is that old user function calls are detected in the prompt and script UIs and a RelaxError raised explaining what to rename the user function to.
Important bugfixes in this release include that relax can run on MS Windows systems again, numerous Python 3 fixes, the ability to [httphttps://wwwgna.nmr-relax.comorg/manualbugs/bruker_read.html ?22411 the ability to load Bruker DC files] when the [https://gna.org/bugs/?22411 file format has corrupted whitespace], the [https://gna.org/bugs/?22501 the GUI "close all analyses" feature works and no longer raises an error], [httphttps://wwwgna.nmr-relax.comorg/manualbugs/structure_create_diff_tensor_pdb.html ?22505 structure.create_diff_tensor_pdb user function] now works when no structural data is present], [https://gna.org/bugs/?22505when no structural data is present], 22502 the geometric prolate diffusion 3D PDB representation in a model-free analysis now aligns with the axis in the PDB as it was previously rotated by 90 degrees], and [https://gna.org/bugs/?22502 previously rotated by 90 degrees], and 22554 the [[Monte Carlo simulation]]s simulations in the relaxation dispersion analysis for exponential curve-fitting for R2eff/R1rho parameter errors is now correct and no longer [https://gna.org/bugs/?22554 underestimating the errors by half].
