Zsh 4.0.7 and 4.1.1 released

Finally, a development version of zsh is available again. 4.1.1 introduces many new features both in the main shell and as library add-ons. It has been in development for some time and is believed to be fairly stable. 4.0.7 is a bug-fix release for the stable branch of zsh. zsh is a shell probably most similar to ksh, but with countless enhancements and differences.
