$Id: NEWS 424 2008-04-15 11:08:42Z wojdyr $ User-visible changes in version 0.8.6 (2008-04-15): * bug fixes (drawing baseline, "zoom all" with log scale) * GUI: parameters (at the bottom of the sidebar) can be changed with Page-Up and Page-Down keys or with mouse wheel. Shift, Ctrl, Alt keys modify speed. * GUI: two buttons added to the "functions" pane in the sidebar. They make HWHM and shape equal for all functions (works only with a few function types) User-visible changes in version 0.8.5 (2008-03-17): * minor changes in syntax: info @0 -> info data in @0 info @0.title -> info title in @0 info @0.filename -> info filename in @0 @0.title = abc -> set @0.title = abc @+ -> @+ = 0 @0.revert -> @0 < . data is exported with "info" now: info @n ( expr1, ... ) > filename where: columns have to be given, @* can be used, F() and Z() can be used without "@n." prefix, *F() can not be used. * xylib: RIET7/LHPM/CSRIET/ILL_D1A5/PSI_DMC .dat filetypes added * non-Windows platforms: using HTML manual (in default browser) instead of HTB * GUI: command line history is stored in ~/.fityk/history * --disable-3rdparty configure flag prevents building with xylib from 3rdparty/ * GUI: added Session -> Save as Image * !foo: executes a command foo by calling system() (from stdlib.h) * bug fixes (there are some bug fixes in every release) * xyConvert tool (can be built only with wxWidgets >= 2.9) User-visible changes in version 0.8.4 (2008-02-15): * xylib: pdCIF format was added User-visible changes in version 0.8.3 (2008-01-25): * data import is done using (modified) xylib library. VAMAS and a few other new file formats are supported. * added hyperbolic functions * command "@n.revert" reloads data points from file * GUI: menu item "Apply to all datasets" was removed. Now all data-related menu items and buttons are applied to datasets selected at the sidebar * GUI: new dataset is opened in a new slot now (it was replacing an active dataset before) User-visible changes in version 0.8.2 (2007-08-21): * multiple fixes for MacOSX, added macosx/ directory (Ken McIvor) * reading multiple y columns from data file: "@+ < foo.xy:0,5/6/7" (or :0,5-7) * "Tip of the day" removed (tips.txt deleted). * added SVG icon (fityk.svg) and MIME type info (fityk.xml) * removed files AUTHORS and ChangeLog * the API is now a Fityk class * GUI: setting baseline as convex hull of data points (experimental) * XPS Shirley background removing * minor improvements and bug fixes (e.g. "reset" was not working in 0.8.1) User-visible changes in version 0.8.1 (2007-04-23): * extended version info can be shown by "info+ version" * displaying Gaussian-FWHM and Lorentzian-FWHM of Voigt function * GUI, MS Windows: configuration is now stored in files, not in registry * GUI: support for any numbers of config files. * changes in command-line parameters * "_EXECUTED_SCRIPT_DIR_/" in scripts is replaced with the script directory * GUI: logarithmic x scale and reversed y scale * bug fixes User-visible changes in version 0.8.0 (2007-03-19): * libfityk (fityk library) if introduced.
