## v0.3.0

>
>
> ⚠️ This release requires Rust 1.91 or later.

### Performance

1. [#30](https://github.com/InfluxCommunity/influxdb3-rust/pull/30): Rewrite the polars DataFrame serializer with typed column iterators
   and the shared ryu/itoa line-protocol writers; \~2.5x faster on wide numeric frames.
   Floats on the DataFrame path now format via ryu, matching `Point`, so extreme
   magnitudes emit exponent notation instead of expanded decimals.

### Dependencies

1. [#20](https://github.com/InfluxCommunity/influxdb3-rust/pull/20): Upgrade Arrow dependencies from version 58 to 59.
2. [#22](https://github.com/InfluxCommunity/influxdb3-rust/pull/22): Upgrade Polars from version 0.53 to 0.54.

* CI updates

## v0.2.0

### Features

1. [#12](https://github.com/InfluxCommunity/influxdb3-rust/pull/12): Expand client configuration support for environment variables and connection strings.
   Add auth scheme and write option support.
   Preserve explicit ports and strip userinfo from normalized hosts.
   Remove the legacy `bucket` and `INFLUX_BUCKET` aliases in favor of `database` and `INFLUX_DATABASE`.
2. [#19](https://github.com/InfluxCommunity/influxdb3-rust/pull/19): Default writes to the V2 API endpoint. Add builder methods for write defaults.`no_sync` requires `use_v2_api=false` to write to the V3 API endpoint.`accept_partial` applies only when writes are sent to the V3 API endpoint and is ignored otherwise.

### Bug Fixes

1. [#13](https://github.com/InfluxCommunity/influxdb3-rust/pull/13): Improve Arrow query result type support.
   Unsupported Arrow types now produce `Error::UnsupportedArrowType` instead of `Null`.

### Dependencies

1. [#18](https://github.com/InfluxCommunity/influxdb3-rust/pull/18): Upgrade Arrow dependencies to version 58 and require Rust 1.89 or later.

## v0.1.0

Initial release.

### Features

* Async client for InfluxDB 3 Core and Enterprise over HTTP (writes) and Arrow
  Flight (queries).
* Write API: a builder accepting line-protocol strings, `Vec<Point>`, and (with
  the `polars` feature) a DataFrame. Options for timestamp precision, batching,
  in-flight concurrency, default tags, gzip, and WAL no-sync.
* Query API: SQL and InfluxQL, parameterised queries, row iteration, and
  streaming of results too large to hold in memory.
* Automatic retries with exponential backoff and full jitter for transient
  failures (transport errors, `429`, `5xx`), honouring `Retry-After`.
  Configurable per client or per request.
* Partial-write error reporting with per-line detail.
* Optional `polars` feature: DataFrame writes and query-to-DataFrame conversion.

### Notes

* Retries are enabled by default (`max_retries = 3`). Use `.no_retry()` or a
  custom `RetryConfig` to change this.
