There was good amount of code change in this version. Still there are many improvements to do in language modules and synthesizer. Some of the language modules requires developers who speak that language. Syntheziser got some improvements and require some amount of research to make the speech more natural. So your feedbacks, suggestions, bug reports and patches are valuable.
PS: A note for quick usage after installation from binary: After installing deb or rpm, Open gedit, edit->preferences->plugins, enable external tools. Dhvani will be available as a plugin there. Select some text in any of the supporting languages and click the Dhvani menu.
