 12. Yet more internal refactoring has removed another argument from the match()
     function. Special calls to this function are now indicated by setting a 
     value in a variable in the "match data" data block. 
+    
+13. Be more explicit in pcre_study() instead of relying on "default" for 
+    opcodes that mean there is no starting character; this means that when new 
+    ones are added and accidentally left out of pcre_study(), testing should 
+    pick them up.
+    
+14. The -s option of pcretest has been documented for ages as being an old 
+    synonym of -m (show memory usage). I have changed it to mean "force study 
+    for every regex", that is, assume /S for every regex. This is similar to -i 
+    and -d etc. It's slightly incompatible, but I'm hoping nobody is still 
+    using it. It makes it easier to run collection of tests with study enabled, 
+    and thereby test pcre_study() more easily.  
+    
+15. When (*ACCEPT) was used in a subpattern that was called recursively, the
+    restoration of the capturing data to the outer values was not happening 
+    correctly.
+    
+16. If a recursively called subpattern ended with (*ACCEPT) and matched an
+    empty string, and PCRE_NOTEMPTY was set, pcre_exec() thought the whole
+    pattern had matched an empty string, and so incorrectly returned a no
+    match.
+    
+17. There was optimizing code for the last branch of non-capturing parentheses,
+    and also for the obeyed branch of a conditional subexpression, which used 
+    tail recursion to cut down on stack usage. Unfortunately, not that there is 
+    the possibility of (*THEN) occurring in these branches, tail recursion is 
+    no longer possible because the return has to be checked for (*THEN). These 
+    two optimizations have therefore been removed.
