The book is a collection of dreams for how we want text to evolve as well as how we understand our current textual infrastructures, how we view the history of writing, and much more. The aim is to make it inspire a powerfully rich future of text in a multitude of ways today and to still have value in a thousand years and beyond. It should serve as a record for how we saw the medium of text and how it relates to our world, our problems and each other in the early twenty first century.
I have been working quite some time on a new front end for the TeX Live Manager tlmgr. Early versions have leaked into TeX Live, but the last month or two has seen many changes in tlmgr itself, in particular support for JSON output. These changes were mostly driven by the need (or ease) of the new frontend: TLCockpit.
