+WiredTiger release 2.6.0, 2015-05-13
+------------------------------------
+
+The WiredTiger 2.6.0 release contains new features, minor API changes and many
+bug fixes.
+
+New features:
+
+* Add support for "at rest" encryption of WiredTiger databases 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 SERVER-18321, WT-1922
+
+* Add enhanced compression support for LZ4. Change is not compatible with
+  tables created with LZ4 compression using earlier versions of WiredTiger.
+  See the upgrading documentation for more information.
+
+API and behavior changes:
+
+* Enhance performance of WT_SESSION::drop with force enabled (mark the table
+  as dead and discard it in the background without writing any content to disk,
+  rather than flushing content from the cache).
+  refs WT-1894
+
+* Add an API to validate configuration strings.
+  refs WT-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 SERVER-17907, WT-1856
+
+
+Significant bug fixes and performance enhancements:
+
+* Fix bugs in checkpoint: committing the checkpoint transaction before it was
+  safe, failure to sync the metadata file before updating the turtle file.
+  refs SERVER-18316
+
+* Don't attempt to validate configuration settings for extensions (collators,
+  compressors, encryptors, extractors). The extension may be valid but not yet
+  loaded so it is not possible to validate.
+
+* Check the magic and version numbers in log files when first opening them.
+
+* Fix a bug with cache leaf size accounting for statistics.
+  refs WT-1885, WT-1919
+
+* Fix a bug where checkpoint could skip a page that was rewritten in memory.
+  refs WT-1946
+
+* Fix a bug in WT_CURSOR::search_near with a random cursor where deleted
+  records could be returned.
+  refs WT-1921, WT-1944
+
+* Fix a bug in handle close where we could fail to clear the open handle
+  flag.
+  refs WT-1915
+
+* Fix a bug in in-memory splits, don't allow any other eviction of a page if
+  the page is being split.
+  refs WT-1916, WT-1917
+
+* Fix a bug in btree open where failure while opening a checkpoint may not
+  clean up completely.
+  refs WT-1598
+
+* Fix a performance problem where long running transactions could continually
+  scan long update chains looking for obsolete entries, when there is no chance
+  of finding any.
+  refs WT-1913
+
+* Fix a performance problem where many threads accessing a single page could
+  prevent WiredTiger from evicting or splitting the page.
+  refs WT-1912
+
+* Fix a source of deadlock bugs by restructuring how we lock handles. Clean
+  up the definition of when it is safe to acquire different locks.
+  refs WT-1598
+
+* Fix a bug where we could evict pages from a file marked as cache resident,
+  add optimizations for cache resident files.
+  refs SERVER-18192
+
+* Fix a deadlock related to LSM (cases where closing a file with an existing
+  checkpoint could self deadlock).
+  refs WT-716
+
+* Only split large in-memory pages if there is a need to keep them in cache
+  (otherwise, it is better to reconcile and evict them immediately).
+  refs WT-1890, WT-1896
+
+* Fix a race on shutdown where the eviction server could still have been
+  accessing files while they were being closed.
+  refs WT-1893
+
+* Fix a case where we could run recovery unnecessarily if there were only
+  non-data changing log records since the last checkpoint.
+  refs WT-1892
+
+* Update API documentation to explain internal session handle usage. This
+  allows users to do specific calculations based on the session_max setting.
+
+* Fix a bug in LSM where updates with overwrite could be skipped incorrectly.
+  refs BF-829
+
+* Fix a cursor bug where searching and traversing in different combinations
+  could lead to data buffers being freed before they should be.
+  refs WT-1887
+
+* Fix a bug when closing bulk cursors, where a file could be left open.
+
+* Fix a bug on Windows related to truncating files (SetEndofFile does not
+  ignore truncation requests like POSIX fallocate).
+
+* Fix a bug in file truncate, where we could truncate to the wrong place if
+  there was a race extending the file at the same time.
+  refs WT-1871
+
+* Fix a bug in reconciliation where page boundary structures could reference
+  freed memory.
+  refs WT-1852
+
+* Change the WT_CURSOR::search and WT_CURSOR::search_near API to first check
+  any currently pinned page before starting a regular descending search.
+
+* Fix a bug in recovery where an error was returned if a transaction spanned
+  an entire log file.
+
+* Fix a bug where recovery could be unnecessarily run during startup.
+
+* Enhance the Python cursor API to allow setting keys and values using array
+  notation.
+
+* Fix a bug where creating a column store with large gaps in the key range
+  would lead to poor performance.
+  refs WT-1807.
+
+* Improve the performance of the core btree search routine by using low-level
+  x86 vectorized search instructions.
