+* Improved our modeling of Go's builtin `html/template` package to understand that these templates provide context-sensitive escaping of HTML and Javascript special characters. This may reduce false-positives seen by the `go/reflected-xss` query, as well as other queries for which HTML escaping is relevant.

+* Improved the Go control-flow graph to exclude more edges representing panics due to comparisons when the types of the compared values indicate a panic is impossible (for example, comparing integers cannot panic). This may reduce false-positives or false-negatives for any query for which control-flow is relevant.
