### Bug fixes 🐛 
* Fix `ReadTimeout` so that it applies to each call to `conn.Read` not just the first read block by @GeorgeMac in https://github.com/ClickHouse/clickhouse-go/pull/1616, @SpencerTorres https://github.com/ClickHouse/clickhouse-go/pull/1617

## Read Timeout behavior changes
This bug fix has potential to affect longer running queries, ensure you're setting `clickhouse.Options` `ReadTimeout` to a reasonable value, and that your `context.WithDeadline` is also set to a reasonable value. The read timeout will now be applied to all blocks, previously it was only set for the first block.

## Upgrades for Dynamic / JSON

Dynamic and JSON were never fully functional in previous versions. If you exceeded the maximum types for `Dynamic`, the data would become unreadable since it was encoded as a single `SharedVariant` type. Same for JSON, if you exceeded the maximum dynamic paths the data would also become unreadable since it was stored in a `SharedData` structure.

In ClickHouse 25.6, a setting was added that abstracts these structures away so that clients don't have to implement them.
To begin using Dynamic and JSON to their fullest ability, upgrade to ClickHouse 25.6 along with clickhouse-go v2.38.0, and enable `output_format_native_use_flattened_dynamic_and_json_serialization` in your connection settings. This will allow you to read all Dynamic and JSON data, even the portions that are stored in the SharedVariant and SharedData blobs on the server.

If you are using older versions of ClickHouse, things will continue to work as before (with the previously mentioned limitations).

Feel free to create an issue in the clickhouse-go repository to report any concerns or bugs with this change.

### HTTP in ClickHouse API

This release includes a bug fix / enhancement for the "ClickHouse API" interface. Previously the only way to use HTTP was through the `database/sql` interface, but now you can use `Protocol: clickhouse.HTTP` in your `clickhouse.Open` options.
HTTP still has some limitations to be aware of for things like batch flushing and session context, so be cautious when switching over code to this protocol. Please report any issues you may have with this change. Native protocol shouldn't be affected, but you can downgrade to v2.36.x if you notice any issues.

- Buffered compression column by column for a native protocol. Introduces the `MaxCompressionBuffer` option - max size (bytes) of compression buffer during column-by-column compression (default 10MiB) [#808](https://github.com/ClickHouse/clickhouse-go/pull/808) by @gingerwizard and @jkaflik
- Support custom types that implement `sql.Scanner` interface (e.g. `type customString string`) [#850](https://github.com/ClickHouse/clickhouse-go/pull/850) by @DarkDrim
- Append query options to the context instead of overwriting [#860](https://github.com/ClickHouse/clickhouse-go/pull/860) by @aaron276h
- Query parameters support [#854](https://github.com/ClickHouse/clickhouse-go/pull/854) by @jkaflik
- Expose `DialStrategy` function to the user for custom connection routing. [#855](https://github.com/ClickHouse/clickhouse-go/pull/855) by @jkaflik

### Bug fixes

- Close connection on `Cancel`. This is to make sure context timed out/canceled connection is not reused further [#764](https://github.com/ClickHouse/clickhouse-go/pull/764) by @gingerwizard
- Fully parse `secure` and `skip_verify` in DSN query parameters. [#862](https://github.com/ClickHouse/clickhouse-go/pull/862) by @n-oden

### Chore

- Added tests covering read-only user queries [#837](https://github.com/ClickHouse/clickhouse-go/pull/837) by @jkaflik
- Agreed on a batch append fail semantics [#853](https://github.com/ClickHouse/clickhouse-go/pull/853) by @jkaflik

## 2.4.3, 2022-11-30
### Bug Fixes
* Fix in batch concurrency - batch could panic if used in separate go routines. <br/>
The issue was originally detected due to the use of a batch in a go routine and Abort being called after the connection was released on the batch. This would invalidate the connection which had been subsequently reassigned. <br/>
This issue could occur as soon as the conn is released (this can happen in a number of places e.g. after Send or an Append error), and it potentially returns to the pool for use in another go routine. Subsequent releases could then occur e.g., the user calls Abort mainly but also Send would do it. The result is the connection being closed in the release function while another batch or query potentially used it. <br/>
This release includes a guard to prevent release from being called more than once on a batch. It assumes that batches are not thread-safe - they aren't (only connections are).
## 2.4.2, 2022-11-24
### Bug Fixes
- Don't panic on `Send()` on batch after invalid `Append`. [#830](https://github.com/ClickHouse/clickhouse-go/pull/830)
- Fix JSON issue with `nil` if column order is inconsistent. [#824](https://github.com/ClickHouse/clickhouse-go/pull/824)

## 2.4.1, 2022-11-23
### Bug Fixes
- Patch release to fix "Regression - escape character was not considered when comparing column names". [#828](https://github.com/ClickHouse/clickhouse-go/issues/828)

## 2.4.0, 2022-11-22
### New Features
- Support for Nullables in Tuples. [#821](https://github.com/ClickHouse/clickhouse-go/pull/821) [#817](https://github.com/ClickHouse/clickhouse-go/pull/817)
- Use headers for auth and not url if SSL. [#811](https://github.com/ClickHouse/clickhouse-go/pull/811)
- Support additional headers. [#811](https://github.com/ClickHouse/clickhouse-go/pull/811)
- Support int64 for DateTime. [#807](https://github.com/ClickHouse/clickhouse-go/pull/807)
- Support inserting Enums as int8/int16/int. [#802](https://github.com/ClickHouse/clickhouse-go/pull/802)
- Print error if unsupported server. [#792](https://github.com/ClickHouse/clickhouse-go/pull/792)
- Allow block buffer size to tuned for performance - see `BlockBufferSize`. [#776](https://github.com/ClickHouse/clickhouse-go/pull/776)
- Support custom datetime in Scan. [#767](https://github.com/ClickHouse/clickhouse-go/pull/767)
- Support insertion of an orderedmap. [#763](https://github.com/ClickHouse/clickhouse-go/pull/763)

### Bug Fixes
- Decompress errors over HTTP. [#792](https://github.com/ClickHouse/clickhouse-go/pull/792)
- Use `timezone` vs `timeZone` so we work on older versions. [#781](https://github.com/ClickHouse/clickhouse-go/pull/781)
- Ensure only columns specified in INSERT are required in batch. [#790](https://github.com/ClickHouse/clickhouse-go/pull/790)
- Respect order of columns in insert for batch. [#790](https://github.com/ClickHouse/clickhouse-go/pull/790)
- Handle double pointers for Nullable columns when batch inserting. [#774](https://github.com/ClickHouse/clickhouse-go/pull/774)
- Use nil for `LowCardinality(Nullable(X))`. [#768](https://github.com/ClickHouse/clickhouse-go/pull/768)

### Breaking Changes
- Align timezone handling with spec. [#776](https://github.com/ClickHouse/clickhouse-go/pull/766), specifically:
    - If parsing strings for datetime, datetime64 or dates we assume the locale is Local (i.e. the client) if not specified in the string.
    - The server (or column tz) is used for datetime and datetime64 rendering. For date/date32, these have no tz info in the server. For now, they will be rendered as UTC - consistent with the clickhouse-client
    - Addresses bind when no location is set
