+- datastore: add vuln and enrich stream updates
+  <details>
+  In an effort to reduce memory consumption during updating the
+  vulnerability database, add support for iterators. Extend Updater
+  interface with `UpdateVulnerabilitiesIter` method that performs
+  the same operation as `UpdateVulnerabilities` but accepts an iterator
+  function instead of a slice. Also, extend the `EnrichmentUpdater`
+  interface with `UpdateEnrichmentsIter` in the same way.
+  </details>
+
+- cpe: add match expression support
+  <details>
+  This adds support for NIST IR 7696, aka CPE2.3 Name Matching. It's
+  anticipated to be used in upcoming CSAF/VEX support. See
+  https://doi.org/10.6028/NIST.IR.7696 for the specification.
