## 0.5.5
### New Features
* Added support for merging two `PathGraph`s via disjoint union to allow results from multiple data flow computations in a single `path-problem` query.
### Major Analysis Improvements
* Removed low-confidence call edges to known neutral call targets from the call graph used in data flow analysis. This includes, for example, custom `List.contains` implementations when the best inferrable type at the call site is simply `List`.
* Added more sink and summary dataflow models for the following packages:
* `java.io`
* `java.lang`
* `java.sql`
* `javafx.scene.web`
* `org.apache.commons.compress.archivers.tar`
* `org.apache.http.client.utils`
* `org.codehaus.cargo.container.installer`
* The main data flow and taint tracking APIs have been changed. The old APIs
remain in place for now and translate to the new through a
backwards-compatible wrapper. If multiple configurations are in scope
simultaneously, then this may affect results slightly. The new API is quite
similar to the old, but makes use of a configuration module instead of a
configuration class.
### Minor Analysis Improvements
* Deleted the deprecated `getPath` and `getFolder` predicates from the `XmlFile` class.
* Deleted the deprecated `getRepresentedString` predicate from the `StringLiteral` class.
* Deleted the deprecated `ServletWriterSource` class.
* Deleted the deprecated `getGroupID`, `getArtefactID`, and `artefactMatches` predicates from the `MavenRepoJar` class.
