 Note that the PCRE 8.xx series (PCRE1) is now in a bugfix-only state. All
 development is happening in the PCRE2 10.xx series.
 
+Version 8.40 11-January-2017
+----------------------------
+
+1.  Using -o with -M in pcregrep could cause unnecessary repeated output when
+    the match extended over a line boundary.
+
+2.  Applied Chris Wilson's second patch (Bugzilla #1681) to CMakeLists.txt for
+    MSVC static compilation, putting the first patch under a new option.
+
+3.  Fix register overwite in JIT when SSE2 acceleration is enabled.
+
+4.  Ignore "show all captures" (/=) for DFA matching.
+
+5.  Fix JIT unaligned accesses on x86. Patch by Marc Mutz.
+
+6.  In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode),
+    without PCRE_UCP set, a negative character type such as \D in a positive
+    class should cause all characters greater than 255 to match, whatever else
+    is in the class. There was a bug that caused this not to happen if a
+    Unicode property item was added to such a class, for example [\D\P{Nd}] or
+    [\W\pL].
+
+7.  When pcretest was outputing information from a callout, the caret indicator
+    for the current position in the subject line was incorrect if it was after
+    an escape sequence for a character whose code point was greater than
+    \x{ff}.
+
+8.  A pattern such as (?<RA>abc)(?(R)xyz) was incorrectly compiled such that
+    the conditional was interpreted as a reference to capturing group 1 instead
+    of a test for recursion. Any group whose name began with R was
+    misinterpreted in this way. (The reference interpretation should only
+    happen if the group's name is precisely "R".)
+
+9.  A number of bugs have been mended relating to match start-up optimizations
+    when the first thing in a pattern is a positive lookahead. These all
+    applied only when PCRE_NO_START_OPTIMIZE was *not* set:
+
+    (a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed
+        both an initial 'X' and a following 'X'.
+    (b) Some patterns starting with an assertion that started with .* were
+        incorrectly optimized as having to match at the start of the subject or
+        after a newline. There are cases where this is not true, for example,
+        (?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that
+        start with spaces. Starting .* in an assertion is no longer taken as an
+        indication of matching at the start (or after a newline).
