Release Notes

The database component is now case sensitive, and so some applications may break, as Wellington de Suza Pinto has noticed. I plan to make the Result array operator case unsensitive, but I didn't have the time to do it for this release.  The gb.qt and gb.gtk now share more code, especially the drawing routines that were moved to a dedicated common component. The features that cannot be common are put in the gb.qt.ext and gb.gtk.ext extension components.

As the drawing routines were put in common, some features were lost:

• The ability to have a rotated transformation matrix with Draw.Rotate().
• The ability to draw rounded rectangles with Draw.RoundRect().

But you gained the ability to draw rich text, with Draw.RichText. Rich text is a subset of HTML, like what you can put in a TextLabel.

The development environment menus were lightly reorganized. The IDE project property component list and the debugging windows were redesigned.  There is a new catalan translation, made by Jordi Sayol. Not that Jordi did not translated the IDE and the database manager only, but all the examples!

And you will find a new experimental component made by Fabien Bodard, gb.chart, that draws... charts.

Change log

Configuration

• BUG: Components written in Gambas do not explicitely use gb.gtk or gb.qt anymore, but gb.gui instead. Otherwise these components could not compile on systems where gb.gtk or gb.qt is disabled.
• BUG: The informer is run again just before compiling the components located in the ./comp sub-directory, so that components like gb.gui, whose *.info files relies on other components, are correctly installed. This workaround does not solve all dependencies possibilities.

Development Environment
