4.1.0.0
4.1.0.0 (2026-11-11 23:14 UTC)
- S3 (4.1.0.0)
- Fixed a bug where TransferUtility.Download/DownloadAsync (the non-multipart path) always waited 100ms after a successful download. The backoff delay now only applies before an actual retry, and the async path uses a non-blocking await instead of a blocking Thread.Sleep.

- Breaking Change: The assembly now has AssemblyVersion 4.0.0.0 and AssemblyFileVersion 4.0.0.x. Version 4.0.0.2 shipped with 0.0.0.0 because the project was missing Properties/AssemblyInfo.cs, so the version from _sdk-versions.json was never applied.

- Added support for the byte, short, bigInteger and bigDecimal model types (Full Numeric Type Support specification): byte maps to sbyte, short to short, bigInteger to System.Numerics.BigInteger and bigDecimal to Amazon.Extensions.Numerics.BigDecimal, serialized without losing digits or scale.
- AWSSDK.Core now depends on AWSSDK.Extensions.Numerics, which provides BigDecimal.
- Breaking Change: Removed support .NET Core 3.1
- Fixed a buffer overflow in ChunkedUploadWrapperStream when an encrypting stream is uploaded with a buffer size that does not divide the chunk size, and reduced the per-chunk allocations of chunked uploads.
- Reduce CPU and memory used by checksums and chunked uploads: stop allocating per 64-byte block in the managed MD5 used to validate GetObject responses, size aws-chunked upload buffers to small payloads, stop allocating a temporary buffer per read when sending trailing checksums, and compute CRC32 with a faster slicing-by-16 implementation on targets where System.IO.Hashing is not vectorized (.NET 8, .NET Standard and .NET Framework).
- Replace checksum provider from the native Amazon Common Runtime to System.IO.Hashing
- All service and extension packages updated to require new Core
