+## 0.0.11
+
+### Breaking Changes
+
+* The deprecated queries `cpp/duplicate-block`, `cpp/duplicate-function`, `cpp/duplicate-class`, `cpp/duplicate-file`, `cpp/mostly-duplicate-function`,`cpp/similar-file`, `cpp/duplicated-lines-in-files` have been removed.
+
+### Deprecated Queries
+
+* The predicates and classes in the `CodeDuplication` library have been deprecated.
+
+### New Queries
+
+- A new query titled "Use of expired stack-address" (`cpp/using-expired-stack-address`) has been added.
+  This query finds accesses to expired stack-allocated memory that escaped via a global variable.
+* A new `cpp/insufficient-key-size` query has been added to the default query suite for C/C++. The query finds uses of certain cryptographic algorithms where the key size is too small to provide adequate encryption strength.
+
+### Minor Analysis Improvements
+
+* The "Failure to use HTTPS URLs" (`cpp/non-https-url`) has been improved reducing false positive results, and its precision has been increased to 'high'.
+* The `cpp/system-data-exposure` query has been modernized and has converted to a `path-problem` query. There are now fewer false positive results.
