This release includes a major overhaul of the [http://www.nmr-relax.com/manual/ relax user manual] with the addition of new chapters and tutorials for all analyses and major expansions and improvements overall. It also includes a major set of bug fixes to re-enable the NOE, R<sub>1</sub> and R<sub>2</sub> analyses of multiple spin types (e.g. the Trp sidechain indole NH), window ordering fixes for the GUI, and numerous other small bug fixes. More details are given below. All users are recommended to upgrade to this newest version.

http://svn.gna.org/svn/relax/tags/2.1.1
<section end=metadata/>
== Features ==
<section begin=features/>
* Creation of extensive tutorials for both the script and GUI modes for the NOE, R1 and R2, model-free chapters with screenshots in of the GUI in operation.
* Restored support for multiple spin types in the NOE, R1 and R2 analyses allowing, for example, tryptophan sidechain indole NE1 data to be analysed.
* A complete rewrite of the [http://www.nmr-relax.com/manual/Relaxation_curve_fitting.html relaxation curve-fitting chapter] of the relax manual.
* General improvements and expansions throughout the user manual (the manual is now 15 Mb compared to 4.3 Mb for relax 2.1.0).
<section end=features/>
== Changes ==
<section begin=changes/>
* Modified the model-free optimisation final printout to be more multi-processor friendly. The message saying that the optimised chi2 is an improvement or not now includes the spin ID string if present. This is more informative for the multi-processor mpi4py printouts.
* Added the use of the program 'nice' to the model-free GUI tutorial in the user manual.
* Import clean ups for the N-state model specific module.
* Added the 'unit' argument to the dipole_pair.read_dist and dipole_pair.set_dist user functions. This is to allow distances in Angstroms to be read into relax and converted to meters.
<section end=changes/>
== Bugfixes ==
* Epydoc docstring fixes for the API documentation.
* Import fix for the epydoc building of the API documentation.
