Release�3.2.1�(16�Sept�2006)<br>
26
~~~~~~~~~~~~~~~~~~~~~~~~~~~~<br>
27
3.2.1�adds�x86/amd64�support�for�all�SSE3�instructions�except�monitor<br>
28
and�mwait,�further�reduces�memcheck's�false�error�rate�on�all<br>
29
platforms,�adds�support�for�recent�binutils�(in�OpenSUSE�10.2�and<br>
30
Fedora�Rawhide)�and�fixes�a�bunch�of�bugs�in�3.2.0.��Some�of�the�fixed<br>
31
bugs�were�causing�large�programs�to�segfault�with�--tool=callgrind�and<br>
32
--tool=cachegrind,�so�an�upgrade�is�recommended.<br>
34
In�view�of�the�fact�that�any�3.3.0�release�is�unlikely�to�happen�until<br>
35
well�into�1Q07,�we�intend�to�keep�the�3.2.X�line�alive�for�a�while<br>
36
yet,�and�so�we�tentatively�plan�a�3.2.2�release�sometime�in�December<br>
