 ## Features/Notes
 
 * Drop-in replacement for RubyParser
 * Should handle 1.9 and later syntax gracefully
 * Requires MRI 2.3 or higher
-* Compatible with RubyParser 3.12.0
+* Compatible with RubyParser 3.13.1
 
 ## Known incompatibilities
 
 RipperRubyParser has some incompatibilities with RubyParser. For some of these,
 the behavior can be changed by turning on extra-compatible mode.
 
 The following incompatibilities cannot be changed:
 
 * RipperRubyParser won't handle non-UTF-8 files without an encoding comment,
   just like regular Ruby
-* RipperRubyParser keeps carriage return characters in heredocs that include them
 * RipperRubyParser does not attempt to match RubyParser's line numbering bugs
+* RipperRubyParser correctly dedents heredocs with interpolations
 
 The following incompatibilities can be made compatible by turning on
 extra-compatible mode:
 
-* RipperRubyParser handles unicode escapes without braces correctly, while
-  RubyParser absorbs trailing hexadecimal characters
-* RipperRubyParser handles the rescue modifier correctly, while RubyParser
-  still contains a bug that was fixed in Ruby 2.4. See RubyParser
-  [issue #227](https://github.com/seattlerb/ruby_parser/issues/227).
-* RubyParser handles byte sequences in second and further literal parts of a
-  strings with interpolations differently. RipperRubyParser will convert these
-  to unicode if possible.
-* RubyParser handles byte sequences in heredocs and interpolating word lists
-  differently. RipperRubyParser will convert these to unicode if possible.
+* Operator assignment of a method call without parentheses to a collection
+  element uses and `:array` S-expression instead of `:arglist`
+* RipperRubyParser keeps carriage return characters in heredocs that include
+  them

-    parser.parse "puts 'Hello World'"
-    # => s(:call, nil, :puts, s(:arglist, s(:str, "Hello World!")))
