+Version 2.8.7 - October 29, 2012
+
+- Fail on select() failing in stratum thread without needing to attempt
+recv_line.
+- Add share to stratum database before sending it again in case we get a
+response from the pool before it's added.
+
+
 Version 2.8.6 - October 29, 2012
 
 - Shorten the initiate stratum connect timeout to 30 seconds.
