+Vim version 9.1 is dedicated to Bram Moolenaar, who passed away on August 3rd 2023
+while still working full-time on Vim.  The Vim project would not exist without
+his ongoing passion to lead and develop Vim and the community for more than 30
+years.  Bram was also passionate about his |ICCF| foundation to help children
+in Uganda.  If you enjoy using Vim, please consider donating!
+We will miss his guidance, passion and leadership.
