    2012-08-24 - - update to 1.6.13: + New export option "ASY" for Asymptote files + Added support for Unicode symbol characters inserted e.g. by cut-and-paste from LibreOffice + Fixed crash on startup due to errors in menu icon setup + Batch mode could crash due to incomplete initialisation of color arrays + Undo/redo in "move fragment"-mode did not work as intended + Default extension is now appended to the save filename as needed + Fixed exporting to files or directories containing spaces in their names - removed upstreamed patches + chemtool-1.6.12-fix_segfault_at_startup.patch and + chemtool-1.6.12-x11linker.patch - added enable-undo, disable-rpath and enable-menu to configure

    2011-12-15 - - fix build on openSUSE-12.1 using patch from - fix segmentation fault on startup

    2009-08-01 - - update to 1.6.12: + This release contains another round of fixes for label positioning and clipping of bonds around labels. + The pen color button has been replaced by a drop-down menu, and a "white" pen for drawing on colored backgrounds has been added. + Chemtool now automatically resizes its main window on small (netbook) screens, and it can also be used in an non-interactive mode to create postscript (etc.) output from previously created chemtool structure files (/usr/bin/chemtoolbg). + The Polish translation has been updated, and a new Bulgarian translation has been added.

    2009-01-17 - - maintained now by openSUSE-Education Team

    2008-09-22 - - fix some rpmlint warnings and beautify specfile

    2008-02-27 - - updated to version 1.6.11 - Key sequences @+ and @- now generate "circle" variants of plus and minus signs - Bond length and zoom factor are now saved in chemtool files and restored on loading - Corrected length calculation for labels without sub- or superscripts (thereby fixing truncation of labels near the edges of a drawing) - Corrected positioning and inter-character spacing of labels with sub- or superscripts - Changed OpenOffice output to avoid LaTeX formatting (that fig2sxd does not support) - Improved clipping of double and triple bonds around labels in the screen view - Improved the preview function to cope with older (pre-1.6) chemtool files - The "gtklp" frontend for CUPS is now available from the "print command" menu - Updated documentation - dropped patch (Makefile.diff)
