 ## Known incompatibilities
 
-RipperRubyParser has some incompatibilities with RubyParser. For some of these,
-the behavior can be changed by turning on extra-compatible mode.
+RipperRubyParser has a few incompatibilities with RubyParser.
 
-The following incompatibilities cannot be changed:
-
 * RipperRubyParser won't handle non-UTF-8 files without an encoding comment,
   just like regular Ruby
-* RipperRubyParser does not match RubyParser's line numbering
-* RipperRubyParser correctly dedents heredocs with interpolations
+* RipperRubyParser does not always match RubyParser's line numbering
 
-The following incompatibilities can be made compatible by turning on
-extra-compatible mode:
-
-* Operator assignment of a method call without parentheses to a collection
-  element uses an `:array` S-expression instead of `:arglist`
-* RipperRubyParser keeps carriage return characters in heredocs that include
-  them
-
