+== NSS `dbm` support removal
+
+Applications that use the Network Security Services (NSS) library often use a database for storing keys, certificates and trust. NSS supports two different storage formats:
+
+* SQLite
+* The `dbm` file format
+
+Nowadays, NSS uses the SQLite file format by default and provides a transparent migration mechanism from `dbm` to SQLite.
+
+The `dbm` file format has been deprecated since Fedora 28 due to various drawbacks, and from Fedora 33 `dbm` will not be supported.
+
+This support removal will slightly reduce the size of the NSS library binary and the developers will be able to focus on the sole file format.
