Still does in Java 6 and 7.
http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#replace(char, char)
http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#replace(char, char)

Same as in Java 5.
http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#replace(java.lang.CharSequence, java.lang.CharSequence)

http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#replaceAll(java.lang.String, java.lang.String)

It hasn't changed, ever.
