 Apache Ignite Release Notes
 ===========================
 
+Apache Ignite In-Memory Distributed Database 2.15.0
+-----------------------------------------------------------
+
+(!) WARNINGS:
+* Removed deprecated daemon mode for Ignite nodes.
+* Removed deprecated ignitevisorcmd tool.
+* Removed legacy JMX metric beans (ThreadPoolMXBean, CacheGroupMetricsMXBean, CacheMetricsMXBean, PersistenceMetricsMXBean, DataStorageMetricsMXBean,  DataRegionMetricsMXBean).
+* Removed redundant ignite-spring to ignite-indexing module dependency. If you use SQL in Ignite and get Ignite dependency via maven, check that you have explicit dependency to the one of the SQL engines (ignite-indexing or ignite-calcite).
+* Moved ignite-ssh module to the ignite-extensions.
+* Deprecated lazy flag of SqlFieldsQuery. Default value for this flag is changed to 'true'.
+* Operations on atomic caches within transactions are forbidden by default now. To allow such operations set system property IGNITE_ALLOW_ATOMIC_OPS_IN_TX to 'true'.
+
+Ignite:
+* Added new feature: Incremental snapshots.
+* Added cache objects transformation feature (this can be used to encrypt, compress or filter the data).
+* Added support of caches with disk page compression for snapshots.
+* Added ability to copy only primary partitions to snapshot.
+* Added an option to skip snapshot check during restore.
+* Added a snapshot exception if a data streamer is loading data with no consistency guarantee.
+* Added storing of snapshot operation warnings to a meta.
+* Added snapshot delta pages sorting.
+* Added partition size and counter check on snapshot create.
+* Added system view for Ignite configuration.
+* Added "Page free space" column to pages lists system views.
+* Added API to kill client (THIN, ODBJ, JDBC) connections.
+* Added metrics for page read time and page replace time.
+* Added thin client affinity hits/misses metric (for partition awareness requests).
+* Added distributed property to disable CDC.
+* Added maximum CDC directory size configuration parameter.
+* Added expiry policy support for CDC.
+* Added ability to provide expireTime during CDC conflict resolution.
+* Added LOB and BLOB fields support to CacheJdbcPojoStore.
+* Added missing "--add-opens" for Java 15+ runtime.
+* Added default constructor to PlatformDotNetSessionLockResult to avoid issues with ReflectionFactory on some application servers.
+* Added ability to use configured FailureHandler for segmentation handling.
+* Added authorization of .NET and C++ compute tasks.
+* Added authorization of Ignite Cluster Node stop/start/restart operations.
+* Added authorization of SQL user management operations.
+* Added 'ADMIN_CLUSTER_STATE' security permission (now it's the only required permission to change cluster state).
+* Granting permissions to system compute tasks by their FQN has been replaced with predefined system permissions.
+* Improved rebalance and PME logging (partition ranges disabled).
+* Default metrics exporter is now the JMX exporter.
+* Optimized index rebuilding (disable writing of WAL records for indexes during rebuilding).
+* Optimized deactivation of large memory regions with persistence.
+* Optimized zeroing of memory pages.
+* Fixed lambdas serialization on Java 17.
+* Fixed PDS defragmentation on Windows.
+* Fixed JDBC connection leak with cache.invoke() over write-behind enabled cache.
+* Fixed an issue that could lead to data corruption of atomic cache when a new updated entry is greater than WAL buffer size.
+* Fixed snapshot create operation started from a non baseline node.
+* Fixed snapshot inconsistency if it was taken under cache workload.
+* Fixed snapshot cancel if one path is configured for several nodes.
+* Fixed snapshot restore hanging if the prepare stage fails.
+* Fixed ignite-cdc stopping on client node crush.
+* Fixed ignite-cdc.sh start failure with non-defailt work directory.
+* Fixed CdcMain state committing during index rebuild.
+* Fixed CdcConsumer stopping on ignite-cdc.sh stop.
+* Fixed the metric for the number of active client sessions.
+* Fixed calculation of cache group storage size related metrics (PagesFillFactor, TotalUsedPages, TotalAllocatedPages).
+* Fixed assertion on histogram update if currentTimeMillis decreases.
+* Fixed REST status code in case of failed request.
+* Fixed an issue that could lead to skipping 3rd party cache store while executing the REST API GET command.
+* Fixed execution options propagation for compute methods.
+* Fixed possible assertion in Communication SPI when the paired connections are set.
+* Fixed potential data loss on historical rebalance.
+* Fixed WAL timeout rollover.
+* Fixed incorrect assertion on CRC calculation when disk page compression is enabled.
+* Fixed node start failure if cpMapSnapshot.bin file is corrupted.
+* Fixed PDS corruption on checkpoint after deactivation.
+* Fixed PDS corruption on deactivation during entries expire.
+* Fixed node failure on rebalancing during caches stop.
+* Fixed NPE in case of simultaneous cache destroy and transaction rollback.
+* Fixed incorrect id check in ClusterGroup.forNodeId.
+* Fixed broken affinity after thick client reconnection.
+* Fixed near cache creation on non-affinity nodes.
+* Fixed possible memory corruption because of insufficient size of compression buffer.
+* Fixed skipping verification of index and metastorage partitions in the snapshot verification process.
+* Fixed criteria skipping after first IN clause for IndexQuery.
+* Fixed WalWritingRate metric for LOG_ONLY and BACKGROUND modes.
+* Updated log4j2 dependency to version 2.20.0.
+* Updated Jetty dependency to 9.4.49.v20220914.

+* Added result saving into log file to idle_verify command.
+* Improved entries versions checking by idle_verify command.
+* Added a command to configure Histogram and Hitrate metrics.
+* Added a command to forcefully resend CDC cache data.
+* Added a command to delete segment CDC links before last gap.
+* Added unified syntax for starting and canceling snapshot operations using control script.
