PerlComposer 0.5 is available

In this version, PerlComposer got better editor based on GtkExText, simple menubar support, Gtk::Table support and
some bug fixes. I intend to produce a beta from this release. Please give me any suggestions, bug reports and even improvement. You're welcome to join this effort to create a VB for UNIX. We need people to write widget, visual design dialogbox and documents. In addition, we need people to package the binary as RPM,SEB or other formats as well.
