+Subject: [PATCH] html: improve Noah's Ark clause performance
+
+Instead of iterating over each element in the stack, and checking each
+attribute against each other attribute in a ~cubic fashion, sort the
+attributes and just use slices.Equal.
+
+Thanks to IPC Labs for reporting this issue.

+Subject: [PATCH] html: escape greater-than symbol in doctype identifiers
+
+During parsing, we unescape character references. When rendering, we
+re-escape certain characters in certain scenarios in order to avoid
+token content causing unexpected parser behavior.
+
+We appear to have not taken this into account when rendering DOCTYPE
+tokens, allowing ">" in PUBLIC/SYSTEM identifier strings, which trigger
+a abrupt-doctype-system-identifier parse error which immediately emits
+the current DOCTYPE token and then continues parsing in the data state.
+
+This may cause bypass in HTML santizers which use the html package for
+parsing.
+
+Thanks to ensy for reporting this issue.
+

+Subject: [PATCH] html: properly render fostered elements in foreign content
+
+When we foster elements under another parent, there are complicated
+rules about which namespace may apply. This in particular affects
+childTextNodesAreLiteral, which checks if we should be emitting raw
+text, or escaped text.
+
+In childTextNodesAreLiteral, check if there is an ancestor which has a
+different namespace. If one is found, check if it's an HTML integration
+point. If not, treat the node as if it were in its parents namespace, if
+so, treat it as HTML.
+
+Thanks to Tristan Madani for reporting this issue.
