## Latest
+## 0.7.0
+
+### Deprecations
+- Following deprecated components are removed:
+ - clickhouse-cli-client
+ - clickhouse-grpc-client
+
+### Important Changes
+- [client-v2] New transport layer implementation is used by default. It is still possible to switch back
+using old implementation by setting `com.clickhouse.client.api.Client.Builder#useNewImplementation` to `false`. (https://github.com/ClickHouse/clickhouse-java/pull/1847)
+
+### New Features
+- [client-v2] Now there is an easy way to set custom HTTP headers globally for client and per operation.
+See `com.clickhouse.client.api.Client.Builder.httpHeader(java.lang.String, java.lang.String)` for details. (https://github.com/ClickHouse/clickhouse-java/issues/1782)
+- [client-v2] Now there is a way to set any server settings globally for client and per operation.
+See `com.clickhouse.client.api.Client.Builder.serverSetting(java.lang.String, java.lang.String)` for details. (https://github.com/ClickHouse/clickhouse-java/issues/1782)
+- [client-v2] Added support for writing AggregateFunction values (bitmap serialization). !! Reading is not
+supported but will be added in the next release. (https://github.com/ClickHouse/clickhouse-java/pull/1814)
+- [r2dbc] Defer connection creation. This allows pool to create a new instance on every subscription,
+instead of always returning the same one. (https://github.com/ClickHouse/clickhouse-java/pull/1810)
+
+### Performance Improvements
+- [client-v2] Improved reading fixed length data like numbers. It is possible to configure readers to
+use pre-allocated buffers to avoid memory allocation for each data row/block. Significantly reduces GC pressure.
+See `com.clickhouse.client.api.Client.Builder.allowBinaryReaderToReuseBuffers` for details. (https://github.com/ClickHouse/clickhouse-java/pull/1816)
+- [client-v2] New API method introduced to read data directly to a POJO. Deserializers for POJO classes are compiled into
+bytecode (with help of https://asm.ow2.io/ library) and optimized for each schema. It is great performance boost
+because data is read without copying it into temporary structures. Code can be optimized by JVM while runtime as SerDe
+code is implemented without reflection using JVM bytecode. Using bytecode makes handling primitive types without values boxing. (https://github.com/ClickHouse/clickhouse-java/pull/1794,
+https://github.com/ClickHouse/clickhouse-java/pull/1826)
+- [client-v2] Optimized reading columns - internally data is read into map of column-values. It is done
+to allow reading same column more than once. Previously map was cleared each row what caused a lot
+internal objects creation. Now values are overridden because schema doesn't change between rows. (https://github.com/ClickHouse/clickhouse-java/pull/1795)
+
+### Documentation
+- [client-v2] Added example for Kotlin (https://github.com/ClickHouse/clickhouse-java/pull/1793)
+- [doc] Main documentation on official ClickHouse website is updated. Each client has its own page with detailed information now.
+Added documentation for the Client V2. See https://clickhouse.com/docs/en/integrations/java.
+
+### Bug Fixes
+- [client-v2] Fix for cases when missing operation metrics were causing NPE. (https://github.com/ClickHouse/clickhouse-java/pull/1846)
+- [client-v2] Fix for handling empty result by BinaryFormat readers. (https://github.com/ClickHouse/clickhouse-java/pull/1845)
+- [jdbc] Content of an artifact 'clickhouse-jdbc-{version}-all.jar' is fixed and contains all required classes from `clickhouse-client`
+and `clickhouse-data`. (https://github.com/ClickHouse/clickhouse-java/pull/1842)
+- [client-v1, jdbc] Endpoints definition parsing fixed to grub properties correctly. Now even properties with key-value
+pairs are supported. (https://github.com/ClickHouse/clickhouse-java/pull/1841, https://github.com/ClickHouse/clickhouse-java/issues/1665)
