+### `vim.configRC` removed

 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

+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
