Version	Published	Release Notes
1.470	30 Oct 2021	See release notes for this release on GitHub: https://github.com/SneakySnail/LIPRAS_470/releases/tag/1.470	Download
1.466.2.0	30 Oct 2021	Update to readme.md
1.466.1.0	16 Oct 2020	Fixing description notes
1.466.0.0	16 Oct 2020	1. Fixed issue with checking for update, need to compile stand-alone version again.
1.465.0.0	3 Apr 2018	1. The 'Update' button, after conducting a fit, was not applying results of LS fit as starting parameters on next LS (i.e. hitting fit data) on the first click 2. Zoom resets on new data 3. Fixed an issue where selecting no file would cause an error
1.460.0.0	2 Apr 2018	1. Read in Rigaku ASC and RAS files 2. Fixed issue with table display on BayesGUI when switching b/w include Bkg or not 3. Added ability to download ZIP file containing LIPRAS update
1.455.0.0	17 Mar 2018	1. Analyze files with a different number of data points in least squares and Bayesian component. Check fitting range before attempting. 2. Bkg refined in least squares can now be used in Bayesian routine 3. Symmetric functions can be made asymmetric
1.430.0.0	13 Mar 2018	1. Fixed an issue that caused the Bayesian of analysis of multiple files to use the SP from the first file and applied it to all files. 2. Bayesian fit plot now sets Xlim to min 2θ and max 2θ used in Least squares
1.429.0.0	9 Nov 2017	Added multipliers to SD and UB/LB bounds Added ability to plot resulting Bayesian fit Bayesian component now checks for Statistics Toolbox Added some logical statements to avoid error of hitting 'plot' when no Bayesian analysis has been conducted
1.428.0.0	9 Nov 2017	Bug fixes to Bayesian GUI. Added ability to plot Sigma^2 trace plot.
1.425.0.0	8 Nov 2017	Bug Fixes, Right-click now delete Bkg points during selection, Introduced alpha version of Bayesian analysis component, which requires Statistics and Machine Learning Toolbox
1.419.0.0	12 Jul 2017	The ‘Check for Updates’ now displays current version and the available version if an update is recommended. Added a try/catch statement to .csv, .xlsx, .xls files for handling 2 or 3 column data (twotheta, intensity), (twotheta, intensity, error).
1.418.0.0	30 Jun 2017	Added an if statement for cases when measured intensity was 0, which would cause the weight of that value to be 'Inf' in MATLAB.
1.417.0.0	30 Jun 2017	Significant improvement to background refinement when 'Refine Bkg' is on
1.414.0.0	28 May 2017	Small changes, 'Default' weight options for CHI files were incorrect. This was a typo, although could be forced by specifying 1/obs. Found out GOF or (reduced chi-square) is sse/dfe which are values found in the Fmodel files.
1.410.0.0	22 May 2017	See Update Notes, Highlight: 1. Fixed an issue that caused the weights of the first pattern to be applied to all the patterns loaded instead of being file dependent 2. The errors from files (FXYE and XYE) are now properly read and applied as weights
1.1.0.0	19 May 2017	Highlights, See update notes for details • Preference Menu has been expanded • Code clean up • Fmodel for individual files are no longer written • Kalpha2 peaks are now written in Fdata file when used
1.0.0.0	21 Apr 2017	Updated description Added Stand-Alone version link for those that want to run LIPRAS without MATLAB Added GitHub webpage Needs Curve Fitting Toolbox to run Updated Description SourceForge now has stand-alone version
