     `Keyword` is now called `Symbol` in ASDL.
 
+  - Defined the behavior of backslash escapes as follows:
+
+    - Escape sequences are only allowed in `text` and `quoted-text`.
+
+    - Newlines are preserved by the parser. This allows proper serialization.
+
+    - Known escape sequences are: `\\` for the literal backslash, `\"` for the
+      literal double quote, `\{` for the literal opening brace and `\u`
+      followed by 4 hex digits for Unicode code points. Representing code
+      points from outside of the Basic Multilingual Plane is made possible with
+      surrogate pairs (two `\uXXXX` sequences). Using the actual character is
+      encouraged, however.
+
+    - Any other escaped characters result in a parsing error.
+
   - Changed the sigil for comments to `//`.
   - Renamed `SelectExpression`'s `expr` field to `expression`.
   - Renamed `Junk`'s and `Comment`s `body` fields to `content`.
