+* 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.
