 Release notes for release 0.7
 
+## Breaking Changes and Migration Guide {#sec-breaking-changes-and-migration-guide-0-7}
+
+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:
+
+[DAG entries in nvf manual]: /index.xhtml#ch-dag-entries
+
+- `vim.configRC` has been removed, which means that you have to convert all of
+  your custom vimscript-based configuration to Lua. As for how to do that, you
+  will have to consult the Neovim documentation and your search engine.
+- After migrating your Vimscript-based configuration to Lua, you might not be
+  able to use the same entry names in `vim.luaConfigRC`, because those have also
+  slightly changed. See the new [DAG entries in nvf manual] for more details.
+
+**Why?**
+
+Neovim being an aggressive refactor of Vim, is designed to be mainly Lua based;
+making good use of its extensive Lua API. Additionally, Vimscript is slow and
+brings unnecessary performance overhead while working with different
+configuration formats.
