[nitpick] This changelog entry is excessively long (over 700 characters) and difficult to parse. Consider breaking it into multiple bullet points to improve readability. For example, separate the general impact, the improvements to specific queries, and the change in query type.

Suggested change

	* The representation of the C# control-flow graph has been significantly changed. This has minor effects on a wide range of queries including both minor improvements and minor regressions. For example, improved precision has been observed for `cs/inefficient-containskey` and `cs/stringbuilder-creation-in-loop`. Two queries stand out as being significantly affected with great improvements: `cs/dereferenced-value-may-be-null` has been completely rewritten which removes a very significant number of false positives. Furthermore, `cs/constant-condition` has been updated to report many new results - these new results are primarily expected to be true positives, but a few new false positives are expected as well. As part of these changes, `cs/dereferenced-value-may-be-null` has been changed from a `path-problem` query to a `problem` query, so paths are no longer reported for this query.
