+Release Notes
+=============
+- Features
+===========
+    - New in Version 4.2.0
+      --------------------
+      This point release heralds many improvements and a host of bug fixes. But there are also some significant changes from previous versions.
+      - Changes
+         - The infrastucture for calculating 2D patterns from 3D orientated objects has been totally re-factored. It is now more accurate and consistent across models.
+         - The way that SasView defines the orientation of anisometric and aligned objects has been completely overhauled. It now differs from previous versions.
+         - Plugin models, including sum/multiply models, have completely migrated to the new infrastructure. ???DO WE NEED TO SAY SOMETHING ABOUT BACKWARD COMPATIBILITY OR LEGACY SUPPORT HERE???
+         - The NeXus loader has been removed (as it is superseded by the NXcanSAS loader).
+      - Improvements
+         - The accuracy/speed of some numerical integrations have been improved. ???CHECK WITH PAULK???
+         - An orientation viewer tool has been introduced (to assist in understanding the new orientation framework).
+         - Problems with the computation of magnetic scattering from some objects have been rectified.
+         - The known issue with the core_shell_parallelepiped model is now fixed.
+         - A number of issues and inconsistencies with the creation of sum|product models have been rectified (and more work is in progress).
+         - A Boltzmann distribution has been added for polydispersity/orientational distributions.
+         - Some batch slicing options have been introduced.
+         - Correlation function analysis now computes both the 1D and 3D functions.
+         - There are several data loading improvements.
+         - There are several improvements to Save/Load Project (with more to come).
+         - There have been numerous other bug fixes.
+      - Documentation
+         Several sections of the help documentation have undergone significant checking and updating, particularly those relating to orientation, magnetic scattering, and polydispersity distributions.
+      - Other work
+         - A Third-Party initiative has recently succeeded in getting SasView to run on Debian. More details at http://trac.sasview.org/wiki/DevNotes/Projects/Debian
+         - With this release we have started to prepare for the inevitable move to Python 3.
+         - SasView 5.0 is already in development. The two most significant features of this version will be (i) a move away from the present WxPython GUIs to new Qt5 GUIs, and (ii) implementation of the Beta-approximation for S(Q). Subject to resources, the latter functionality may be released (in a non-GUI form) in an interim SasView 4.3.0.

+       - Fixes a path typo
+       - 64 bit and 32 bit Windows executables now available
+      It is recommended that all users upgrade to this version
+    - New in Version 4.1.1
+      --------------------
+      This point release is a bug-fix release addressing:
+       - Fixes #948: Mathjax CDN is going away
+       - Fixes #938: Cannot read canSAS1D file output by SasView

+       - Updated tutorials for SasView 4.x.y
+    - New in Version 4.1.0
+      ------------------
+      This incremental release brings a series of new features and improvements,
+      and a host of bug fixes. Of particular note are:
+      - Correlation Function Analysis (Corfunc)
+        This performs a correlation function analysis of one-dimensional SAXS/SANS data,
+            or generates a model-independent volume fraction profile from the SANS from an
+            adsorbed polymer/surfactant layer.
+            A correlation function may be interpreted in terms of an imaginary rod moving
+            through the structure of the material. Î1D(R) is the probability that a rod of
+            length R moving through the material has equal electron/neutron scattering
+            length density at either end. Hence a frequently occurring spacing within a
+            structure manifests itself as a peak.
+            A volume fraction profile \Phi(z) describes how the density of polymer
+            segments/surfactant molecules varies with distance from an (assumed locally flat)
+            interface.
+      - Fitting of SESANS Data
+        Data from Spin-Echo SANS measurements can now be loaded and fitted. The data will
+            be plotted against the correct axes and models will automatically perform a Hankel
+            transform in order to calculate SESANS from a SANS model.
+      - Documentation
+        The documentation has undergone significant checking and updating.
+      - Improvements
+        - Correlation function (corfunc) analysis of 1D SAS data added from CCP13
+        - File converter tool for multi-file single column data sets
+        - SESANS data loading and direct fitting using the Hankel transformation
+        - Saving and loading of simultaneous and constrained fits now supported
+        - Save states from SasView v3.x.y now loaded using sasmodel model names
+        - Saving and loading of projects with 2D fits now supported
+        - Loading a project removes all existing data, fits, and plots
+        - Structure factor and form factor can be plotted independently
+        - OpenCL is disabled by default and can be enabled through a fit menu
+        - Data and theory fields are now independently expandable

+        - Fixes #858: Hayter MSA S(Q) returns errors
+        - Numerous grammatical and contexual errors in documention
+    - New in Version 4.0.1
+      ------------------
+      This release fixes the critical bug #750 in P(Q)*S(Q).  Most damaging
+      it appears that the background term was being added to S(Q) prior to
+      multiplication by P(Q).

+     - Fixes bug #468 broken remove constraint buttons in
+       simultaneous/constrained fitting panel
+     - Fixes bug #474 resulting from changes in 3.1.1 that had
+       introduced an error in the high-Q of slit-smeared models.

+       in SasView crashing even if left alone.
+     - Fixes bug #479 missing help button on simultaneous/constrained fit page
+     - Fixes bug #480 GUI resizing issues on simultaneous fit page
+     - Fixes bug #486 broken Report Results
+     - Fixes bug #488 redraw issues in fit page
+   - New in Version 3.1.1
+     --------------------
+     - Fixes bug #457 that prevented SasView from starting if the user was not
+       connected to the internet, or was behind a proxy server.
+   - New in Version 3.1.0
+     --------------------
+     - The documentation/help has had a complete overhaul including:
+       - A completely new presentation interface (Sphinx).
+       - Proof reading!
+       - Updating for latest features.
+       - A Help (or sometimes ?) button has been added to every panel, and some
+         sub panels if appropriate, linking to the appropriate section in the
+         documentation.
+       - The model help has been split so that the Details button now brings up
+         a very short pop-up giving the equation being used while HELP goes to
+         the section in the full documentation describing the model.
+       - Extensive help has also been added for the new optimizer engine (see
+         below) including rules of thumb on how and when to choose a given
+         optimizer and what the parameters do.
+     - The optimizer engine has been completely replaced. The new optimizer
+       still defaults to the standard Levenberg-Marquardt algorithm. However 4
+       other optimizers are now also available. Each starts with a set of default
+       parameters which can be tuned. The DREAM optimizer takes the longest but
+       is the most powerful and yields rich information including full parameter
+       correlation and uncertainty plots. A results panel has been added to
+       accommodate this.
+       - The five new optimizers are:
+         - A Levenberg-Marquardt optimizer
+         - A Quasi-Newton BFGS optimizer
+         - A Nelder-Mead Simplex optimizer
+         - A Differential Evolution optimizer
+         - A Monte Carlo optimizer (DREAM)
      - New models were added:
+       - LamellarPolLz
+         - MicelleSphCoreModel (currently residing in the Uncategorized category)
      - Existing models were updated:
+       - LamellarPS and LamellarPSHG have been changed to LamellarCaille and
+         LamellarCailleHG
+         - LamellarPS (bug in polydispersity integration fixed)
+         - RectangularPrismModel
+         - RectangularHollowPrismModel
+         - RectangularHollowPrismInfThinWallsModel
+     - Infrastructure to allow SESANS data to be fit with models was added. This
+       will become available in a future release but can currently be used from
+       the command line with some caveats.
+     - A number of bugs were fixed including a thread crashing issue and an
+       incorrect slit smearing resolution calculation.
+     - Implemented much more robust error logging to enable much easier
+       debugging in general but particularly the debugging of issues reported by
+       SasView users.
+     - A number of infrastructure tasks under the hood to enhance maintainability
+     - Upgrade from Wx 2.8 to Wx 3.0.2 which allows several new features but
+       required significant additional rework as well.
+     - Fully implemented Sphinx to the build process to produce both better
+       user documentation and developer documentation.
+     - Restructuring of the code base to more unified nomenclature and structure
+       so that the source installation tree more closely matches the installer
+       version tree.
+     - Code cleanup (an ongoing task) .
+     - Migration of the repository to github simplifying contributions from
+       non-project personnel through pull requests.
+   - New in Version 3.0.0
+     --------------------
+     - The GUI look and feel has been refactored to be more familiar for
+       Windows users by using MDI frames. Graph windows are also now free-
+       floating.
+     - Five new models have been added: PringlesModel, CoreShellEllipsoidXTModel,
+       RectangularPrismModel, RectangularHollowPrismModel and
+       RectangularHollowPrismInfThinWallsModel.
+     - The data loader now supports ILL DAT data files and reads the full meta
+       information from canSAS file formats.
+     - Redefined convention for specifying angular parameters for anisotropic
+       models.
+     - A number of minor features have been added such as permitting a log
+       distribution of points when using a model to simulate data, and the
+       addition of a Kratky plot option to the linear plots.
+     - A number of bugs have also been fixed.
+     - Save Project and Save Analysis now work more reliably.
+     - BETA: Magnetic contrast supporting full polarization analysis has been
+       implemented for some spherical and cylindrical models.
+     - BETA: Two new tools have been added:
+       - A generic scattering calculator which takes an atomic, magnetic or
+         SLD distribution in space and generates the appropriate 2D
+         scattering pattern. In some cases the orientationally averaged
+         (powder) 1D scattering can also be computed. Supported formats
+         include: SLD or text, PDB, and OMF magnetic moment distribution
+         file.
+       - An image viewer/converter for data in image format; this reads in
+         an image file and will attempt to convert the image pixels to
+         data. Supported formats include: TIFF, TIF, PNG, BMP, JPG.

+       depending on the choice of axis scale of the plot) to the linear fits
+     - Added more models
+   - Feature set from previous versions
+     -----------------------------------
+     - Perspectives Available
+       - Invariant calculator: Calculates the invariant, volume fraction, and
+         specific surface area.
+       - P(r) inversion calculator: Indirect Fourier transformation method.
+       - Fitting: the tool used for modeling and fitting 1D and 2D data to
+         analytical model functions
+       - Tools: provides a number of useful supplementary tools such as SLD
+         calculation
+     - Fitting
+       - Includes a large number of model functions, both form factors and structure factors.
+       - Support P(Q)*S(Q) for form factors that flag they can be so multiplied.
+       - Supports Gaussian, lognormal, Shulz, rectangular and custom distribution
+         functions for models that need to include polydispersity or for orientational
+         distributions if appropriate.
+       - Anisotropic shapes and magnetic moment modeling in 2D allow for a non-uniform
+         distribution of orientations of a given axis leading to modeling and fitting
+         capabilities of non azimuthaly symmetric data.
+       - User can choose to weight fits or not. If using weights, the user can choose
+         the error bar on each point if provided in the file, the square root
+         of the intensity or the intensity itself.
+       - Instrumental resolution smearing of model or fits is provided with several
+         options: read the resolution/point fromt he file. Input a pinhole resolution
+         or a slit resolution.
+       - Users can define the Qrange (Qmin and Qmax) for both 1D and 2D data for
+         fitting and modeling, but not graphically.  The range can be reset to the
+         defaults (limits of q in data set for a fit) with the reset button.
+       - A mask can be applied to 2D calculation and fitting.
+       - Normalized residual plots are provided with every fit.
+       - Model function help available through detail button or from the fitting panel.
+       - Simultaneous/(advanced)constrained fitting allows for fitting a single
+         data set or several different sets simultaneously with the application
+         of advanced constraints relating fit parameters to functions of other
+         parameters (including from a different set). For example thickness of
+         shell = sin(30) times the length.
+       - Models that are the sum of two other models can be easily generated through the
+         SUM Model menubar item.
+       - New Python models can be added on the fly by creating an appropriate Python
+         file in the model plugin directory. Two tools are provided to help:
+         An easy to use custom model editor allows the quick generation of new Python
+         models by supplying only the parameters and their default value (box 1)
+         and the mathematical function of the model (box 2) and generating the
+         necessary *.py file.  A separate advanced model editor provides a full Python
+         file editor.  Either way once saved the model becomes immediately available
+         to the application.
+       - A batch fitting capability allows for the analysis of a series of data sets to
+         a single model and provides the results in a tabular form suitable for saving
+         or plotting the evolution of the fit parameters with error bars (from within
+         the application).
+     - Tools
+       - A scattering length density calculator,including some X-ray information
+         is provided.
+       - A density to vol. fraction converter is provided
+       - In application access to a Python shell/editor (PyCrust) is provided
+       - An instrument resolution calculator, including possible gravitational and
+         TOF effects is provided

+       - A kiessig fringe thickness calculator is provided
+     - Plots and plot management
+       - A 3D graphing option (for 2d data/results) is provided with the view
+         controlled by the mouse
+       - 2D plots are shown with an intensity color bar. 2D Color map can be user
+         adjusted.
+       - Supports output of plot to a variety of graphic formats. Supported formats
+         include: png, eps, emf, jpg/jpeg, pdf, ps, tif/tiff, rawRGBbitmap(raw, rgba),
+         and scalable vector graphic (svg/svgz)
+       - Supports ouput of data in plot (1 or 2D) to limited data formats
+       - Multiple data sets can be loaded into a single graph for viewing (but a fit
+         plot can currently only have a single plot).
+       - Extensive context sensitive plot/fitting/manipulation options are available
+         through a right mouse click pop-up menu on plots.
+     - Data management
+       - Supports 2 + column 1D ASCII data, NIST 1D and 2D data, and canSAS data
+         via plug-in mechanism which can easily allow other readers as appropriate.
+       - 2D data is expected in Q space but for historical reasons accepts the
+         NIST 2D raw pixel format and will do conversion internally.
+       - The full data and metadata available to SasView is viewable in ASCII via
+         right clicking on a data set and choosing Data Info in the DataExplorer
+         or on the plots
+       - Supports loading a single file, multiple files, or a whole folder
+       - An optional Data Explorer is provided (default) which simplifies managing,
+         plotting, deleting, or setup for computation. Most functions however do
+         not require access to the explorer/manager and can be accessed through
+         right click menus and the toolbar.  The data explorer can be re-started
+         from the menu bar.
+     - Data manipulation
+       - Support various 2D averaging methods : Circular, sectors, annular,
+         boxsum, boxQx and boxQy.
+       - A 2D data maks editor is provided
+       - 2D mask can be applied to the circular averaging.
+     - Miscellaneous features
+       - limited reports can be generated in pdf format
+       - Provides multiprocessor support(Windows only)
+       - Limited startup customization currently includes default startup
+         data folder and choice of default starting with data manager
+       - Limited support for saving(opening) a SasView project or a SasView analysis
+         (subproject) is provided.
+       - SasView can be launched and loaded with a file of interesty by double-clicking
+         on that file (recognized extension)
+       - A data file or data folder can be passed to SasView when launched from
+         the command line.
+       - Limited bookmarking capability to later recall the results of a fit calculation
+         is provided.
+       - Extensive help is provided through context sensitive mouse roll-over,
+         information bar (at the bottom of the panel), the console menu, and
+         access to the help files in several different ways.
+- Downloading and Installing
+=============================
+   *** Note 1:  Much more information is available at www.sasview.org under links.
+                    Look in the 'For Developers' section and particularly the wiki at
+                www.sasview.org/trac/wiki.
+   *** Note 2:  If you have EXE or ZIP SasView installer, you won't need any of
+                the following.  However it is highly recommended that any
+                previous versions be un-installed prior to installing the
+                new version.
+.1- System Requirements
+        - Python version >= 2.5 and < 3.0 should be running on the system
+        - We currently use Python 2.7
+.2- Installing from source
+        - Get the source code
+          - to follow the current development version from source control use
+              git clone https://github.com/SasView/sasview.git
+              git clone https://github.com/bumps/bumps.git
+          - to install a specific version
+        - Build, install and run a specific release

+- Known Issues
+===============
+.1- All systems:
+      The conversion to sasmodels infrastructure is ongoing and should be
+      completed in the next release. In the meantime this leads to a few known
+      issues:
+        - The way that orientation is defined is being refactored to address
+        long standing issues and comments.  In release 4.1 however only models
+        with symmetry (e.g. a=b) have been converted to the new definitions.
+        The rest (a <> b <> c - e.g. parellelepiped) maintain the same
+        definition as before and will be converted in 4.2.  Note that
+        orientational distribution also makes much more sense in the new
+        framework.  The documentation should indicate which definition is being
+        used for a given model.
+        - The infrastructure currently handles internal conversion of old style
+        models so that user created models in previous versions should continue
+        to work for now. At some point in the future such support will go away.
+        Everyone is encouraged to convert to the new structure which should be
+        relatively straight forward and provides a number of benefits.
+        - In that vein, the distributed models and those generated by the new
+        plugin model editor are in the new format, however those generated by
+        sum|multiply models are the old style sum|multiply models. This should
+        also disappear in the near future
+        - The on the fly discovery of plugin models and changes thereto behave
+        inconsistently.  If a change to a plugin model does not seem to
+        register, the Load Plugin Models (under fitting -> Plugin Model
+        Operations) can be used.  However, after calling Load Plugin Models, the
+        active plugin will no longer be loaded (even though the GUI looks like
+        it is) unless it is a sum|multiply model which works properly.  All
+        others will need to be recalled from the model dropdown menu to reload
+        the model into the calculation engine.  While it might be annoying it
+        does not appear to prevent SasView from working..
+        - The model code and documentation review is ongoing. At this time the
+        core shell parellelepiped is known to have the C shell effectively fixed
+        at 0 (noted in documentation) while the triaxial ellipsoid does not seem
+        to reproduce the limit of the oblate or prolate ellipsoid. If errors are
+        found and corrected, corrected versions will be uploaded to the
+        marketplace.
+.1- All systems:
+        - The documentation window may take a few seconds to load the first time
+          it is called. Also, an internet connection is required before
+          equations will render properly. Until then they will show in their
+          original TeX format.
+        - If the documentation window remains stubbornly blank, try installing a
+          different browser and set that as your default browser. Issues have
+          been noted with Internet Explorer 11.
+        - Check for Updates may fail (with the status bar message ' Cannot
+          connect to the application server') if your internet connection uses
+          a proxy server. Tested resolutions for this are described on the
+          website FAQ.
+        - The copy and paste functions (^C, ^V) in the batch mode results grid
+          require two clicks: one to select the cell and a second to select the
+          contents of the cell.
+        - The tutorial has not yet been updated and is somewhat out of date
+        - Very old computers may struggle to run the 3.x and later releases
+        - Polydispersity on multiple parameters included in a simultaneous/
+          constrained fit will likely not be correct
+        - Constrained/simultaneous fit page does not have a stop button
+        - Constrained/simultaneous fit do not accept min/max limits
+        - Save project does not store the state of all the windows
+        - Loading projects can be very slow
+        - Save Project only works once a data set has been associated with
+          a model.  Error is reported on status bar.
+        - There is a numerical precision problem with the multishell model when
+          the iner radius gets large enough (ticket #288)
+        - The angular distribution angles are not clearly defined and may in
+          some cases lead to incorrect calculations(ticket #332)
+.2- Windows:
+        - If installed to same directory as old version without first removing
+          the old version, the old desktop icon will remain but point to the
+          new exe version. Likewise all the start menu folders and items will
+          have the old name even though pointing to the new version.  Usually
+          safest to uninstall old version prior to installing new version anyway.
+.3- MAC:
+        - Application normally starts up hidden. Click icon in Dock to view/use
+          application.
+        - Multiprocessing does not currently work on MAC OS
+.4- Linux:
+        - Not well tested
