> https://dist.apache.org/repos/dist/dev/ignite/2.7.0-rc1/
>
> Git tag name is 2.7.0-rc1
>
> This release includes the following changes:
>
> Apache Ignite In-Memory Database and Caching Platform 2.7
> ---------------------------------------------------------
>
> Ignite:
> * 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 annotation
> * 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 changes
> * 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
>
> SQL:
> * 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, NODE_ATTRIBUTES, NODE_METRICS, BASELINE_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 REPLICATED and PARTITIONED caches
> * 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
>
> JDBC:
> * Implemented DataSource interface for the thin driver
>
> ODBC:
> * Added streaming mode support
> * Fixed crash in Linux when there are more than 1023 open file descriptors
> * Fixed bug that prevented cursors on a server from being closed
> * Fixed segmentation fault when reusing a closed connection
>
> Web Console:
> * Added new metrics: WAL and Data size on disk
> * Added support for "collocated" query mode on Query screen
> * Added support for Java 9+ for Web Agent.

> * Fixed fail when working with web sockets
>
> REST:
> * Added option IGNITE_REST_GETALL_AS_ARRAY for array format in "getAll"
> call
>
> Visor:
> * Added output of node "Consistent ID"
> * Visor now collects information about cache groups instead of separate
> caches to reduce memory consumption
> * Improved help for "start" command
