| 2 | +=== |
| 3 | + |
| 4 | +### Services |
| 5 | +* Synced the V2 SDK with latest AWS service API definitions. |
| 6 | + |
| 7 | +### SDK Breaking changes |
| 8 | +* This update includes breaking changes to how the DynamoDB AttributeValue (un)marshier handles empty collections. |
| 9 | + |
| 10 | +### Deprecations |
| 11 | +* `service/s3/s3crypto`: Deprecates the crypto client from the SDK ([#394](https://github.com/aws/aws-sdk-go-v2/pull/394)) |
| 12 | + * s3crypto client is now deprecated and may be removed from the future versions of the SDK. |
| 13 | +* `aws`: Removes plugin credential provider ([#391](https://github.com/aws/aws-sdk-go-v2/pull/391)) |
| 14 | + * Removing plugin credential provider from the v2 SDK developer preview. This feature may be made available as a separate module. |
| 15 | +* Removes support for deprecated Go versions ([#393](https://github.com/aws/aws-sdk-go-v2/pull/393)) |
| 16 | + * Removes support for Go version specific files from the SDK. Also removes irrelevant build tags, and updates the README.md file. |
| 17 | + * Raises the minimum supported version to Go 1.11 for the SDK. Older versions may work, but are not actively supported |
| 18 | + |
| 19 | +### SDK Features |
| 20 | +* `service/s3/s3manager`: Add Upload Buffer Provider ([#404](https://github.com/aws/aws-sdk-go-v2/pull/404)) |
| 21 | + * Adds a new `BufferProvider` member for specifying how part data can be buffered in memory. |
| 22 | + * Windows platforms will now default to buffering 1MB per part to reduce contention when uploading files. |
| 23 | + * Non-Windows platforms will continue to employ a non-buffering behavior. |
| 24 | +* `service/s3/s3manager`: Add Download Buffer Provider ([#404](https://github.com/aws/aws-sdk-go-v2/pull/404)) |
| 25 | + * Adds a new `BufferProvider` member for specifying how part data can be buffered in memory when copying from the http response body. |
| 26 | + * Windows platforms will now default to buffering 1MB per part to reduce contention when downloading files. |
| 27 | + * Non-Windows platforms will continue to employ a non-buffering behavior. |
| 28 | +* `service/dynamodb/dynamodbattribute`: New Encoder and Decoder Behavior for Empty Collections ([#401](https://github.com/aws/aws-sdk-go-v2/pull/401)) |
| 29 | + * The `Encoder` and `Decoder` types have been enhanced to support the marshaling of empty structures, maps, and slices to and from their respective DynamoDB AttributeValues. |
| 30 | + * This change incorporates the behavior changes introduced via a marshal option in V1 ([#2834](https://github.com/aws/aws-sdk-go/pull/2834)) |
| 31 | + |
| 32 | +### SDK Enhancements |
| 33 | +* `internal/awsutil`: Add suppressing logging sensitive API parameters ([#398](https://github.com/aws/aws-sdk-go-v2/pull/398)) |
| 34 | + * Adds suppressing logging sensitive API parameters marked with the `sensitive` trait. This prevents the API type's `String` method returning a string representation of the API type with sensitive fields printed such as keys and passwords. |
| 35 | + * Related to [aws/aws-sdk-go#2310](https://github.com/aws/aws-sdk-go/pull/2310) |
| 36 | + * Fixes [#251](https://github.com/aws/aws-sdk-go-v2/issues/251) |
| 37 | +* `aws/request` : Retryer is now a named field on Request. ([#393](https://github.com/aws/aws-sdk-go-v2/pull/393)) |
| 38 | +* `service/s3/s3manager`: Adds `sync.Pool` to allow reuse of part buffers for streaming payloads ([#404](https://github.com/aws/aws-sdk-go-v2/pull/404)) |
| 39 | + * Fixes [#402](https://github.com/aws/aws-sdk-go-v2/issues/402) |
| 40 | + * Uses the new behavior introduced in V1 [#2863](https://github.com/aws/aws-sdk-go/pull/2863) which allows the reuse of the sync.Pool across multiple Upload request that match part sizes. |
| 41 | + |
| 42 | +### SDK Bugs |
| 43 | +* `service/s3/s3manager`: Fix index out of range when a streaming reader returns -1 ([#378](https://github.com/aws/aws-sdk-go-v2/pull/378)) |
| 44 | + * Fixes the S3 Upload Manager's handling of an unbounded streaming reader that returns negative bytes read. |
| 45 | +* `internal/ini`: Fix ini parser to handle empty values [#406](https://github.com/aws/aws-sdk-go-v2/pull/406) |
| 46 | + * Fixes incorrect modifications to the previous token value of the skipper. Adds checks for cases where a skipped statement should be marked as complete and not be ignored. |
| 47 | + * Adds tests for nested and empty field value parsing, along with tests suggested in [aws/aws-sdk-go#2801](https://github.com/aws/aws-sdk-go/pull/2801) |
