+## Changes from v0.4.5 to v0.5.0
+
+- `GridFileBuilder` has been introduced into legacy C++ driver, luamongo don't
+  implements it any more. The constructor has been changed and now it only
+  receives an instance of GridFS class.
+
+- `db:ensure_index()` function has been replaced by `db:create_index()`. The
+  parameters of the new function are `create_index(ns,keys,options)` where
+  `keys` and `options` can be Lua tables or JSON strings (both dictionaries
+  which allow 'unique' and 'name' fields).
+
+- `db:get_indexes()` is now `db:enumerate_indexes()`.
+
+- `db:reset_index_cache()` has been removed.
+
+- `gridfs:find_file()` requires a query. It has been added
+  `gridfs:find_file_by_name(filename)` equivalent to old implementation.
