# Improvements to Python analysis The following changes in version 1.25 affect Python analysis in all applications. ## General improvements ## New queries | **Query** | **Tags** | **Purpose** | |-----------------------------|-----------|--------------------------------------------------------------------| ## Changes to existing queries | **Query** | **Expected impact** | **Change** | |----------------------------|------------------------|------------------------------------------------------------------| ## Changes to libraries * Importing `semmle.python.web.HttpRequest` will no longer import `UntrustedStringKind` transitively. `UntrustedStringKind` is the most commonly used non-abstract subclass of `ExternalStringKind`. If not imported (by one mean or another), taint-tracking queries that concern `ExternalStringKind` will not produce any results. Please ensure such queries contain an explicit import (`import semmle.python.security.strings.Untrusted`).
