+### Important Changes
+- [Client-V1] Fix for handling DateTime without timezone when `session_timezone` is set. Now server timezone 
+is parsed from server response when present (https://github.com/ClickHouse/clickhouse-java/issues/1464)
 
 ### New Features 
 - [Client-V1/Apache HTTP] More configuration parameters for connection management. Useful for tuning performance.
 (https://github.com/ClickHouse/clickhouse-java/pull/1771)
     - com.clickhouse.client.config.ClickHouseClientOption#CONNECTION_TTL - to configure connection time-to-live
     - com.clickhouse.client.http.config.ClickHouseHttpOption#KEEP_ALIVE_TIMEOUT - to configure keep-alive timeout
-    - com.clickhouse.client.http.config.ClickHouseHttpOption#CONNECTION_REUSE_STRATEGY - to configure how connection 
-are resued in the connection pool.
+    - com.clickhouse.client.http.config.ClickHouseHttpOption#CONNECTION_REUSE_STRATEGY - defines how connection pool behaves.
+If `FIFO` is selected then connections are reused in the order they were created. It results in even distribution of connections.
+If `LIFO` is selected then connections are reused as soon they are returned to the pool. 
+Note: only for `APACHE_HTTP_CLIENT` connection provider. 
     - Additionally switched to using LAX connection pool for Apache Connection Manager to improve performance 
 for concurrent requests.
 - [Client-V2] Connection pool configuration https://github.com/ClickHouse/clickhouse-java/pull/1766
     - com.clickhouse.client.api.Client.Builder.setConnectionRequestTimeout - to configure connection request timeout.
 Important when there are no connections available in the pool to fail fast. 
-    - com.clickhouse.client.api.Client.Builder.setMaxConnections - total max connections per route.
+    - com.clickhouse.client.api.Client.Builder.setMaxConnections - configures how soft limit of connections per host.
+Note: Total number of connections is unlimited because in most cases there is one host.
     - com.clickhouse.client.api.Client.Builder.setConnectionTTL - to limit connection live ignoring keep-alive from server.
     - com.clickhouse.client.api.Client.Builder.setConnectionReuseStrategy - to configure how connections are used.
 Select FIFO to reuse connections evenly or LIFO (default) to reuse the most recently active connections.
 - [Client-V2] All operations are now executed in calling thread to avoid extra threads creation. 
 Async operations can be enabled by `com.clickhouse.client.api.Client.Builder.useAsyncRequests` (https://github.com/ClickHouse/clickhouse-java/pull/1767)
-- [Client-V2] Spring Demo Service as usage example (https://github.com/ClickHouse/clickhouse-java/pull/1765)
-- [Client-V2] More examples for using text based formats (https://github.com/ClickHouse/clickhouse-java/pull/1752)
 - [Client-V2] Content and HTTP native compression is supported now Currently only LZ4 is available. (https://github.com/ClickHouse/clickhouse-java/pull/1761) 
 - [Client-V2] HTTPS support added. Required to communicate with ClickHouse Cloud Services.
 Client certificates are supported, too. (https://github.com/ClickHouse/clickhouse-java/pull/1753)
 - [Client-V2] Added support for HTTP proxy (https://github.com/ClickHouse/clickhouse-java/pull/1748)

 ### Bug Fixes
 - [Client-V2] Data is read fully from a stream. Important for Cloud instances (https://github.com/ClickHouse/clickhouse-java/pull/1759)
 - [Client-V2] Timezone from a server response is now used to parse DateTime values (https://github.com/ClickHouse/clickhouse-java/pull/1763)
