It is a great pleasure to announce, on behalf of the Editors of Theory and Applications of Categories, that Valeria de Paiva of Xerox Palo Alto Research Center, Martin Hyland of the University of Cambridge and Stephen Lack of the University of Sydney have been elected and agreed to serve as Editors. We look forward to collaborating with the new Editors. Their contact information is available from the TAC Web pages. With regret, we also announce the retirement as Editor of Andrew Pitts of the University of Cambridge. Andy is a founding Editor of TAC and we sincerely express our gratitude for his helpful contributions since 1995.
