3.1.0.379

• Adding support for reading/writing SimpleAggregateFunctionType #69
• Exposed PostStreamAsync as public #60
• Fix: ExecuteNonQuery always returned 0 #64
• Adding GetUInt16, GetUInt32, GetUInt64, GetTuple, GetIPAddress functions to DataReader #63
• Fixed: DataReader: should not throw exception on empty dataset #58

3.0.0.357

• !! WARNING: BREAKING CHANGE !!: Removed type conversions to improve performance. If a column in a query returns Int16, you cannot use GetInt32 on it anymore - the method must match the type exactly.
• Improved: Will not throw an EndOfStreamException internally during normal work
• Improved: Better handling of errors on connection opening #55
• Improved: Handle complex column names in BulkCopy #54
• Improved: Added support for Tuple larger than 7 elements #46

2.3.0.326

• Improved: BulkCopy will work on very wide tables (with thousands of columns) (#45).
  • Fix requires ClickHouse version 20.5 or higher. Client will work with older server version but wide tables would not be supported

2.2.2.294

• Improved: BulkCopy will work on very large tables (with thousands of columns)

Note: this release has been hidden from "stable" nuget feed due to compatibility issues. You can still install it by specifying the version manually

2.2.0.279

• Added ability to specify custom settings (e.g. wait_end_of_query, buffer_size) (#40)
• Internal: Will use default_format query parameter instead of rewriting SQL

2.1.0.269

• BREAKING GetFieldType will now return underlying type for Nullable columns (e.g.: int instead of Nullable<int>), improving compatibility with ORMs (Dapper in particular - #6)
• ClickHouseConnection will throw an exception if provided HttpClient cannot handle decompression specified in connection string
• Added IClickHouseCommand, IClickHouseConnection interfaces

2.0.0.262

• BREAKING removed support for TSV/JSON drivers, will only use binary now
• BREAKING enabled compression by default in all connections. If you pass a HttpClient to connection constructor, make sure it is configured to perform decompression (or use Compression=false in connection string)
• Added support for reading raw result as returned by ClickHouse (ExecuteRawResultAsync)
• Improved Decimal performance
• Improved cancellation mechanics
• Refactoring of serialization internals, for better performance in some cases
• Parameters will correctly use InvariantCulture where relevant
