+WiredTiger release 1.2.0, 2012-06-04
+------------------------------------
+
+This release contains many bugfixes and improvements. The major changes are:
+
+[#138] Add support for transactions with coarse-grained durability.
+ Transactions provide atomicity guarantees and rollback, and uncommitted
+ changes are never written to disk. There is no on-disk log, so
+ committed changes only become durable when the next checkpoint
+ completes. Checkpoints are implemented by creating
+ transactionally-consistent snapshots within data files.
+
+[#156] Fully support operations that make schema changes with multiple
+ sessions open concurrently.
+
+[#159] Disable internal page key suffix compression if a custom collator is
+ configured. This avoids issues with collators that require complete
+ keys.
+
+[#167] Add support for durable snapshots within files. While a snapshot is
+ active, the pages used by the snapshot will not be overwritten. If a
+ file is accessed after a crash or application exit without calling
+ WT_CONNECTION::close, any changes made after the last snapshot will be
+ silently ignored.
+
+[#214, #216]
+ Fixes for forcing eviction with small caches.
