Some entries in +the changelog now reference JIRA tickets that can be found at: + + http://jira.mongodb.org + +New features and API changes: + +* Add support for storing large values on-page in a btree rather than in + an overflow item. This is useful for workloads that want to keep large + items in cache - since WiredTiger overflow items are never cached. + It is configured via new `leaf_value_max` configuration setting. This + enhancement led to the deprecation of internal_item_max and leaf_item_max + configuration settings, see upgrading documentation for further + information. [#1282] + +* Add support for compressing log files. When configured each compressable + log record will be compressed. This is configure with the + `log=(compressor=X)` configuration setting. See upgrading documentation + for further information. [#1359] + +* No longer return EBUSY when opening a bulk cursor, verifying or salvaging + a database if a checkpoint is currently running. This allows + applications to do these exclusive operations without shutting down the + checkpoint server thread. [#1397] [#1404] SERVER-16236 SERVER-16457 + +* Add support for immutable indexes. [#1344] + +* Added several new statistics, improved accuracy for some statistics + tracking and simplified mechanism for querying a particular statistic. + [#1505] + +* Have the eviction server write out unnecessary pages prior to the cache + reaching the configured eviction trigger size. This can reduce the + amount of eviction application threads do when configured with a large + cache. + +* Several enhancements to managing how long we keep files open + +* Revert a change in the 2.4.1 release that caused the WT_ROLLBACK (and + deprecated WT_DEADLOCK) error return to map to different numeric values. + Applications should ensure they are compiling against the same version + of the wiredtiger.h header file as the library they link against, + otherwise odd behavior will be experienced. + +* Support setting configuration strings to "none" as being equivalent to an + empty string in most cases. [#1417] + +* Enhance the hot backup implementation to allow recovery to be run between + incremental backups. [#1183] + +Other significant changes: + +* Improve performance of cursor open when there are many tables in a database. + [#1391] [#1443] + +* Reduce the impact checkpoints have on concurrent operations. This was + done by changing how we lock tables. [#1391] [#1392] + +* Improve performance when scanning a table that has many deleted items. + SERVER-16247 + +* Fix a bug in checkpoint, where the metadata (turtle) file wasn't being + synced on checkpoint. [#1383] + +* Fix a bug where WiredTiger could accumulate memory during page splits and + never free it. SERVER-16546 + +* Many enhancements and bug fixes for Windows. + +* Fix a bug where a custom extractor terminate was being called twice. + [#1503] + +* Fix a bug where a race between closing a handle and checkpointing could + lead to errors. [#1495] [#1497] + +* Validate the block header checksum before we clear it - if the checksum + field had been corrupted, we didn't notice. SERVER-16457 + +* Fix a bug in write conflict detection. Cursors configured with + no-overwrite could sometimes not see update conflicts for deleted + records. SERVER-16351 + +* Several bug fixes and performance improvements in LSM including: + - Add support for custom collators in LSM trees. [#1361] + - Fix a bug in LSM search_near, where it returned a deleted item. + BF-694, BF-700 + - Improve background maintenance operations so that the cache does + not get full unnecessarily. + - Fix a bug that could lead to updates being written into old chunks. + [#1432] [#1418] + - Fix a bug in background merge that could skip updates. SERVER-16123 + +* Fix a bug when maintaining the cache, that could cause checkpoints to + skip writing an update that should have been included. [#1419] SERVER-16336 + +* Fix a bug in WT_SESSION::drop, where failures generated error output even + when force was specified. [#1436] + +* Fix a bug in WiredTiger integer packing code when figuring out how much + space is required for a value (it can shrink as numbers grow). SERVER-16118 + +* Several enhancements to the wtstats.py tool that generates graphs from + standard WiredTiger statistics logs. [#1365] + +* Fix a bug on OS X where fsync isn't sufficient to flush a file, use + fcntl(F_FULLFSYNC) instead. + +* Work around a bug in clang 3.5.0 compare and swap primitive. The + __sync_bool_compare_and_swap version of the API in clang produces bad + code for us with -O3 optimization enabled. + + WiredTiger release 2.4.1, 2014-11-06 ------------------------------------ @@ -1,6 +1,6 @@ -WiredTiger 2.4.2: (November 6, 2014) +WiredTiger 2.5.0: (December 24, 2014) -This is version 2.4.2 of WiredTiger. +This is version 2.5.0 of WiredTiger.
