-6 Changes in version 0.4
-************************
+6 Change history
+****************
+
+6.1 Version 0.5
+===============
+
+The GUI has been rewritten in Tcl/Tk, removing the dependence on the
+Ruby/Tk interface library.
+
+The Windows installer now installs a small Ruby subset and the standard
+epspdf distribution, but with epspdftk.tcl replaced with a starpack: a
+single executable containing `epspdftk.tcl' and a Tcl/Tk runtime. See
+`http://wiki.tcl.tk/52'.
+
+Epspdf now uses its own subdirectory for both the logfile and the
+configuration file. For Linux/Unix/Mac OS X this is `$HOME/.epspdf',
+for Windows it is `%APPDATA%\epspdf'. On all supported platforms,
+settings are stored in the file `config' in this directory. Under
+Windows, the registry is no longer used for this.
+
+A button has been added to view log output.
+
+There is a second new button "Remove temp files", which is normally
+checked, causing temporary files to be deleted after each conversion.
+Unchecking this button may be useful for troubleshooting. In previous
+versions, temporary files were deleted at the end of the entire
+epspdftk session but that has become less practical now that the GUI and
+epspdf itself have become two separate programs.
+
+The "Open with..." option for Windows has been dropped for technical
+reasons.
+
+The "-version" option now prints the version string instead of setting
+the desired pdf version.
+
+The "-info" option now also prints the number of pages for pdf files.
+
+6.2 Version 0.4
+===============
Hi-res boundingboxes are now supported. By default, conversion from eps
to pdf now uses the hires boundingbox as "page" to determine the page
-dmensions of the pdf file. Other conversions preserve or generate a
+dimensions of the pdf file. Other conversions preserve or generate a
hires boundingbox.
