 ### Minor Analysis Improvements
 
-* The `cpp/unclear-array-index-validation` ("Unclear validation of array index") query has been improved to reduce false positives increase true positives.
+* The `cpp/unclear-array-index-validation` ("Unclear validation of array index") query has been improved to reduce false positives and increase true positives.
 * Fixed false positives in the `cpp/uninitialized-local` ("Potentially uninitialized local variable") query if there are extraction errors in the function.
 * The `cpp/incorrect-string-type-conversion` query now produces fewer false positives caused by failure to detect byte arrays.
 * The `cpp/incorrect-string-type-conversion` query now produces fewer false positives caused by failure to recognize dynamic checks prior to possible dangerous widening.

 ### Minor Analysis Improvements
 
 * Modelled that `re.finditer` returns an iterable of `re.Match` objects. This is now understood by the API graph in many cases.
-* Type tracking, and hence the API graph, is now able to correctly trace trough comprehensions.
+* Type tracking, and hence the API graph, is now able to correctly trace through comprehensions.
 * More precise modelling of the dataflow through comprehensions. In particular, captured variables are now handled correctly.
 * Dataflow out of yield is added, allowing proper tracing through generators.
 * Added several models of standard library functions and classes, in anticipation of no longer extracting the standard library in a future release.
