 In v0.7 we are removing `vim.configRC` in favor of making `vim.luaConfigRC` the
 top-level DAG, and thereby making the entire configuration Lua based. This
 change introduces a few breaking changes:

+### `vim.maps` rewrite {#sec-vim-maps-rewrite}
+
+Instead of specifying map modes using submodules (eg.: `vim.maps.normal`), a new
+`mode` option has mode has been introduced. It can be either a string, or a list
+of strings, where a string represents the short-name of the map mode(s), that
+the mapping should be set for. See `:help map-modes` for more information.
+
+For example:
+
+```nix
+vim.maps.normal."<leader>m" = { ... };

+
+has to be replaced by

+```nix
+vim.maps."<leader>m" = {
