 PCRE2 is the name used for a revised API for the PCRE library, which is a set
 of functions, written in C, that implement regular expression pattern matching
-using the same syntax and semantics as Perl, with just a few differences. Some
-features that appeared in Python and the original PCRE before they appeared in
-Perl are also available using the Python syntax. There is also some support for

+using the same syntax and semantics as Perl, with just a few differences. After 
+nearly two decades, the limitations of the original API were making development 
+increasingly difficult. The new API is more extensible, and it was simplified
+by abolishing the separate "study" optimizing function; in PCRE2, patterns are
+automatically optimized where possible. Since forking from PCRE1, the code has 
+been extensively refactored and new features introduced.
