 - Fix the bug that the default note directory is within packages directory. If it happens, it **deletes** all of existing notes. If you read this before updating the package, please check your note directory before updating it.

+## Migration
+
+v0.1.0 under published package name `notational-velocity` had a fatal bug that sets the default value of its note directory under package directory. Since package directory is overwritten when the user updates `notational-velocity` package. For more information, refer [#25][6].
+
+To resolve this problem, we renamed our package name to `nvatom`. Users who have the old `notational-velocity` need to **install `nvatom` package first**, activate the package to automatically migrate the existing notes, and then delete `notational-velocity` package.
+
+Since keymaps overlap with `notational-velocity`, follow the menu *Packages > nvAtom > Toggle* to activate this package.
