     stack recursion. This gives a massive performance boost under BSD, but just
     a small improvement under Linux. However, it saves one field in the frame
     in all cases.

  6. Added more features from the forthcoming Perl 5.10:
- 
+
     (a) (?-n) (where n is a string of digits) is a relative subroutine or
         recursion call. It refers to the nth most recently opened parentheses.
-        
+
     (b) (?+n) is also a relative subroutine call; it refers to the nth next
-        to be opened parentheses.     
-        
-    (c) Conditions that refer to capturing parentheses can be specified 
+        to be opened parentheses.

+    (c) Conditions that refer to capturing parentheses can be specified
         relatively, for example, (?(-2)... or (?(+3)...
-

     (d) \K resets the start of the current match so that everything before
-        is not part of it.  
-        
+        is not part of it.
+
     (e) \k{name} is synonymous with \k<name> and \k'name' (.NET compatible).

+
     (f) \g{name} is another synonym - part of Perl 5.10's unification of
-        reference syntax.

- 7. Added two new calls to pcre_fullinfo(): PCRE_INFO_OKPARTIAL and 
-    PCRE_INFO_JCHANGED. 
-    
- 8. A pattern such as  (.*(.)?)*  caused pcre_exec() to fail by either not 
-    terminating or by crashing. Diagnosed by Viktor Griph; it was in the code 
+        reference syntax.

     for detecting groups that can match an empty string.
-    
+
+ 9. A pattern with a very large number of alternatives (more than several
+    hundred) was running out of internal workspace during the pre-compile
+    phase, where pcre_compile() figures out how much memory will be needed. A
+    bit of new cunning has reduced the workspace needed for groups with
+    alternatives. The 1000-alternative test pattern now uses 12 bytes of
+    workspace instead of running out of the 4096 that are available.
