+WiredTiger release 1.4.0, 2012-12-03
+------------------------------------
+
+This release adds several major new features, a number of performance
+improvements and bug fixes. The significant changes are outlined below:

+ routine select how many rows are included in each disk block.
+
+[381] Add statistics to track read and write amplification (application data
+ size versus I/O size)
+
+* Add a trigger configuration option to WT_SESSION::compact API.
+
+* Make WT_SESSION::create's checksum configuration 3-state: on, off, or
+ uncompressed blocks only.
+
+Bug fixes:
+
+* Fix build issues on Solaris.
+
+* Fix a bug calculating the generation of an LSM merge.
+
+* Fix WiredTiger dump and load for tables.
