 WiredTiger release 2.6.0, 2015-05-13
 ------------------------------------
 
-The WiredTiger 2.6.0 release contains major new features and important bug fixes.
+The WiredTiger 2.6.0 release contains new features, minor API changes and many
+bug fixes.
+
+New features:
+
+* Add support for encrypting WiredTiger tables via a new encryption API.
+  refs WT-1822
+
+* Add support for bulk load in LSM trees. Previously the bulk configuration for
+  cursor create was ignored by LSM trees.
+  refs WT-1922 SERVER-18321
+
+* Add support for raw compression in LZ4. Change is not compatible with tables
+  created with LZ4 compression using earlier versions of WiredTiger. See
+  upgrading documentation for more information.
 
 API and behavior changes:
 
-TODO: Move contet into this section.
+* Enhance performance of WT_SESSION::drop with force enabled. Don't flush
+  content from cache before returning from the API call, instead mark the tree
+  as dead and discard it in the background without writing any content to disk.
+  WT-1894
+
+* Add an API to validate configuration strings.
+  refs #1739
+
+* Disallow the cache_resident flag on LSM trees.
+  refs WT-1905
+
+* Enhance the controls for how aggressively idle handles are closed. Update the
+  wiredtiger_open file_manager configuration options to expose that control.
+  refs WT-1856 SERVER-17907

-* Avoid obsolete update checks during long-running transactions.  There can potentially be long chains of updates that cannot be freed: there is no point repeatedly scanning them.
+* Fix a performance problem where long running transactions could continually
+  scan long update chains looking for obsolete entries, when there is no chance
