## 0.4.0

### New Queries

* Added a new medium-precision query, `cpp/missing-check-scanf`, which detects `scanf` output variables that are used without a proper return-value check to see that they were actually written. A variation of this query was originally contributed as an [experimental query by @ihsinme](https://github.com/github/codeql/pull/8246).

### Minor Analysis Improvements

* Modernizations from "Cleartext storage of sensitive information in buffer" (`cpp/cleartext-storage-buffer`) have been ported to the "Cleartext storage of sensitive information in file" (`cpp/cleartext-storage-file`), "Cleartext transmission of sensitive information" (`cpp/cleartext-transmission`) and "Cleartext storage of sensitive information in an SQLite database" (`cpp/cleartext-storage-database`) queries. These changes may result in more correct results and fewer false positive results from these queries.
* The alert message of many queries have been changed to make the message consistent with other languages.
