smithy-rs/CHANGELOG.md

## vNext (Month Day Year)
**New This Week**
- :bug: Correctly encode HTTP Checksums using base64 instead of hex. Fixes aws-sdk-rust#164. (#615)
- (When complete) Add profile file provider for region (#594, #xyz)

## v0.18.1 (July 27th 2021)
* Remove timestreamwrite and timestreamquery from the generated services (#613)

## v0.18 (July 27th 2021)
**Breaking changes**
* `test-util` has been made an optional dependency and has moved from
  aws-hyper to smithy-http. If you were relying on `aws_hyper::TestConnection`, add `smithy-client` as a dependency
  and enable the optional `test-util` feature. This prunes some unnecessary dependencies on `roxmltree` and `serde_json`
  for most users. (#608)

**New This Week**
- :tada: Release all but three remaining AWS services! Glacier, IoT Data Plane and Transcribe streaming will be available in a future release. If you discover that a service isn't functioning as expected please let us know! (#607)
- :bug: Bugfix: Fix parsing bug where parsing XML incorrectly stripped whitespace (#590, aws-sdk-rust#153)
- Establish common abstraction for environment variables (#594)
- Add windows to the test matrix (#594)
- :bug: Bugfix: Constrain RFC-3339 timestamp formatting to microsecond precision (#596)

## v0.17 (July 15th 2021)

**New this Week**
* 🎉 Add support for Autoscaling (#576, #582)
* `AsyncProvideCredentials` now introduces an additional lifetime parameter, simplifying bridging it with `#[async_trait]` interfaces
* Fix S3 bug when content type was set explicitly (aws-sdk-rust#131, #566, @eagletmt)
