+WiredTiger release 1.2.2, 2012-06-20
+------------------------------------
+
+This is a bugfix release. The changes are as follows:
+
+* Defer making free pages available until the end of a checkpoint, in case
+ there is a failure after processing some files.
+
+* When checking the value of the "isolation" key, don't assume it is NUL
+ terminated. This bug could cause transactions to run with incorrect
+ isolation.
+
+* Fix two bugs with snapshot isolation:
+
+ 1. reset the isolation level when the transaction completes;
+ 2. when checking visibility, check item's ID against the maximum snapshot ID
+ (not the transaction's ID).
+
+
