7.0.0

Breaking Changes

• Update Swift version to 6.3.
• Compressing an empty Data now produces a valid empty gzip stream instead of returning an empty Data.
• Decompressing an empty Data now throws GzipError instead of returning an empty Data.

New

• Support typed throw.
• Conform GzipError, GzipError.Kind, and CompressionLevel to Hashable.
• Conform CompressionLevel to Comparable.

Changes

• Make maxWindowBits a module-level constant.
• Show zlib error messages when GzipError is handled as Error.
• Improve the error message when decompression cannot make progress.
• Find zlib headers installed outside /usr/include on Linux, such as Linuxbrew.
• Improve memory allocation when decompressing small inputs.

Fixes

• Fix accessing types with the Gzip module prefix, such as Gzip.CompressionLevel.
• Avoid a crash when compressing or decompressing data larger than 4 GiB; compression now throws an error instead.
