Full Changelog: brantburnett/Snappier@release/1.2.0...release/1.3.0-beta.1

1.2.0

Major Changes

• Support for block compression and decompression using ReadOnlySequence<byte> as the source and IBufferWriter<byte> as the destination
• Snappy.TryCompress and Snappy.TryDecompress overloads that return false instead of throwing an exception if the output buffer is too small
• SnappyStream compression now recognizes blocks that compress poorly and encodes them as uncompressed data
• Temporary buffers returned to the ArrayPool are now cleared with zeroes before they are returned to protect any sensitive data being compressed or decompressed. This adds some overhead but benchmarks showed it wasn't very significant and it's worthwhile for better security.
• General performance improvements
• Improved documentation

1.1.4

This release primarily includes performance improvements around stream decompression in .NET 8, but does show some minor decompression improvements on other runtimes (except .NET 4.8 which is not a priority). Also includes a bug fix for a stream decompression corner case.

1.1.1

This release includes some fixes to logic that could have caused unsafe memory access in cases where GC rearranges memory if they occurred at the precise moment when an out-of-range reference was on the stack. These moments are very short-lived and should be impossible to create intentionally, but they still represent a security risk.

Full Changelog: brantburnett/Snappier@release/1.1.0...release/1.1.1

1.1.0

Breaking Changes

This release no longer includes explicit support for the unsupported runtimes .NET Core 3.0/3.1 or .NET 5.0. These runtimes are now supported via the .NET Standard 2.0 target. While they should still function, it is untested and the lack of hardware intrinsic support will most likely result in degraded performance compared to 1.0.

What's Changed

• All use of GC pinning and fixed buffers has been replaced with byte references and System.Runtime.CompilerServices.Unsafe. This should have less impact on garbage collection performance, especially on systems with continuous Snappy load.
• Reduced heap allocations
• Ported some performance improvements from the reference implementation that were added since the original port
• Lots more performance tweaks

Performance

This release sees a consistent improvement in both compression and decompression performance across all supported frameworks on my Core i7-10850H CPU, especially on decompression. On .NET 6, the time was reduced by 18% when compressing 64KB of HTML and 52% when decompressing. In some cases, the decompression time is reduced by as much as 66%.
