## 0.6.0 (2022-12-08)

### Features Added

* Added BlobDeleteType to DeleteOptions to allow access to ['Permanent'](https://learn.microsoft.com/rest/api/storageservices/delete-blob#permanent-delete) DeleteType.
* Added [Set Blob Expiry API](https://learn.microsoft.com/rest/api/storageservices/set-blob-expiry).

### Breaking Changes

* Corrected the name for `saoid` and `suoid` SAS parameters in `BlobSignatureValues` struct as per [this](https://learn.microsoft.com/rest/api/storageservices/create-user-delegation-sas#construct-a-user-delegation-sas)
* Updated type of `BlockSize` from int to int64 in `UploadStreamOptions`

* Field `XMSContentCRC64` has been renamed to `ContentCRC64`
* The `Lease*` constant types and values in the `blob` and `container` packages have been moved to the `lease` package and their names fixed up to avoid stuttering.
* Fields `TransactionalContentCRC64` and `TransactionalContentMD5` have been replaced by `TransactionalValidation`.
* Fields `SourceContentCRC64` and `SourceContentMD5` have been replaced by `SourceContentValidation`.
* Field `TransactionalContentMD5` has been removed from type `AppendBlockFromURLOptions`.

### Bugs Fixed

* Corrected signing of User Delegation SAS. Fixes [#19372](https://github.com/Azure/azure-sdk-for-go/issues/19372) and [#19454](https://github.com/Azure/azure-sdk-for-go/issues/19454)

* Uploading block blobs larger than 256MB can fail in some cases with error `net/http: HTTP/1.x transport connection broken`.
* Blob name parameters are URL-encoded before constructing the complete blob URL.

### Other Changes

* Added some missing public surface area in the `container` and `service` packages.
* The `UploadStream()` methods now use anonymous memory mapped files for buffers in order to reduce heap allocations/fragmentation.
  * The anonymous memory mapped files are typically backed by the page/swap file, multiple files are not actually created.
