 Apache Ignite Release Notes
+Apache Ignite In-Memory Database and Caching Platform 2.7
+* Added experimental support for multi-version concurrency control with snapshot isolation
+  - available for both cache API and SQL
+  - use CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT to enable it
+  - not production ready, data consistency is not guaranteed in case of node failures
+* Implemented Transparent Data Encryption based on JKS certificates
+* Implemented Node.JS Thin Client
+* Implemented Python Thin Client
+* Implemented PHP Thin Client
+* Ignite start scripts now support Java 9 and higher
+* Added ability to set WAL history size in bytes
+* Added SslContextFactory.protocols and SslContextFactory.cipherSuites properties to control
which SSL encryption algorithms can be used
+* Added JCache 1.1 compliance
+* Added IgniteCompute.withNoResultCache method with semantics similar to ComputeTaskNoResultCache
+* Spring Data 2.0 is now supported in the separate module 'ignite-spring-data_2.0'
+* Added monitoring of critical system workers
+* Added ability to provide custom implementations of ExceptionListener for JmsStreamer
+* Ignite KafkaStreamer was upgraded to use new KafkaConsmer configuration
+* S3 IP Finder now supports subfolder usage instead of bucket root
+* Improved dynamic cache start speed
+* Improved checkpoint performance by decreasing mark duration.
+* Added ability to manage compression level for compressed WAL archives.
+* Added metrics for Entry Processor invocations.
+* Added JMX metrics: ClusterMetricsMXBean.getTotalBaselineNodes and ClusterMetricsMXBean.getActiveBaselineNodes
+* Node uptime metric now includes days count
+* Exposed info about thin client connections through JMX
+* Introduced new system property IGNITE_REUSE_MEMORY_ON_DEACTIVATE to enable reuse of allocated
memory on node deactivation (disabled by default)
+* Optimistic transaction now will be properly rolled back if waiting too long for a new topology
on remap
+* ScanQuery with setLocal flag now checks if the partition is actually present on local node
+* Improved cluster behaviour when a left node does not cause partition affinity assignment
+* Interrupting user thread during partition initialization will no longer cause node to stop
+* Fixed problem when partition lost event was not triggered if multiple nodes left cluster
+* Fixed massive node drop from the cluster on temporary network issues
+* Fixed service redeployment on cluster reactivation
+* Fixed client node stability under ZooKeeper discovery
+* Massive performance and stability improvements
+Ignite .Net:
+* Add .NET Core 2.1 support
+* Added thin client connection failover
+Ignite C++:
+* Implemented Thin Client with base cache operations
+* Implemented smart affinity routing for Thin Client to send requests directly to nodes containing
data when possible
+* Added Clang compiler support
+* Added experimental support for fully ACID transactional SQL with the snapshot isolation:
+  - use CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT to enable it
+  - a transaction can be started through native API (IgniteTransactions), thin JDBC driver
or ODBC driver
+  - not production ready, data consistency is not guaranteed in case of node failures
+* Added a set of system views located in "IGNITE" schema to view cluster information (NODES,
+* Added ability to create predefined SQL schemas
+* Added GROUP_CONCAT function support
+* Added string length constraint
+* Custom Java objects are now inlined into primary and secondary indexes what may significantly
improve performance when AFFINITY_KEY is used
+* Added timeout to fail query execution in case it cannot be mapped to topology
+* Restricted number of cores allocated for CREATE INDEX by default to 4 to avoid contention
on index tree Fixed transaction hanging during runtime error on commit.
+* Fixed possible memory leak when result set size is multiple of the page size
+* Fixed situation when data may be returned from cache partitions in LOST state even when
PartitionLossPolicy doesn't permit it
+* Fixed "Caches have distinct sets of data nodes" during SQL JOIN query execution between
+* Fixed wrong result for SQL queries when item size exceeds the page size
+* Fixed error during SQL query from client node with the local flag set to "true"
+* Fixed handling UUID as a column type
+* Implemented DataSource interface for the thin driver
+* Added streaming mode support
+* Fixed crash in Linux when there are more than 1023 open file descriptors

+* Added orphaned local and remote transactions and ability to rollback them
+* Added "--dump" flag to dump current partition state to file.
