-        | Dear spaCy users,
-
-    p Unfortunately, we (Henning Peters and Matthew Honnibal) are parting ways. Breaking up is never easy, and it's taken us a while to get our stuff together. Hopefully, you didn't notice anything was up — if you did, we hope you haven't been inconvenienced.
-
-    p Here's how this is going to work: Matt will continue to develop and maintain spaCy and all related projects under his name. Nothing will change for you. Henning will take over our legal structure and start a new business under a new name.
-
-    p Sincerely,#[br] Henning Peters and Matthew Honnibal
