I should have released this months ago but here we are!

Big thanks to @Bond-009 for the perf! and thanks to @Erior for the fix!

Breaking changes:

• .NET 1.3 and 2.0 only well turns out support will be for: 1.3, 2.0, 2.1 and NET46. Can't wait to drop more.

Improvements:

• Use System.Buffers
• Use nameof
• Use functions from System.Memory
• Reduce Allocations

Fixes:

• Fix for nested uncompressed Zips in Zips

Bug Fixes:

• Fix: ArchiveEncoding was ignored in TarWriterOptions
• For RAR's encryption - Memory and speed optimization
• Various fixes for ZIP64 writer (zero byte entries, 32 bit where supported)
• Fix for clients failing on just having a 64 bit offset in ZIP64
• Handle a bad extra field in a local file header in zip files
• Return a bounded substream when data descriptors are used in seekable zips
• fix filename garbling in tar(#414)

Lots of stuff from users!

New features:

• Changes to populate ZipArchive.ZipVolumne.Comment
• Tar symlink support
• Allow Flush on EntryStream
• file search support linq Pattern

Fixes:

• Tar filename with exactly 100 characters gets cut
• Recognise empty tar archives
• Enable parallel test execution
• Avoid throwing NotSupportedException in ReaderFactory hot path

Mostly fixes this release.

• Implemented ReadByte/WriteByte on streams to improve performance
  
• Fixed EFS Handling
• Correctly set IsEncrypted For Rar5
• Zip Slip fix for Reader extensions

Allow forced encoding to override default encoding for zip

Features

• RAR5 thanks to @coderb for starting a report of the RAR code. There's still a large section that needs to be ported so for RAR format 2.9 it uses old code paths.
• Expose Stream length if available

Fixes

• Security fix Prevent paths from escaping base provided path
• Use IBM encoding when non-UTF8 as per zip spec
• LZip disposal fix
• Bouncy Castle namespace conflict fix

Features

• Deflate64 support
• Allow Tar Archive writing finalization to be optional
• Improved Skipping on Seekable streams

Fixes

• Entry ToString
• Cake updated to 0.26 for building

Change namespace and visibility to avoid collisions

Absorb arraypool from CoreFX

New Features:

• .NET Core 2 / .NET Standard 2.0 Support
• Mk/add support for extracting password protected LZMA(2) 7z archives
• Use arraypool for transfer/skip

Bug Fixes:

• Opening 7zip archive with invalid win32 date
• eliminate spurious rar crc exception
• create new memorystream to allow proper resizing as memorystream could be a user provided buffer

All fixes contributed from users!

Bug fixes:

• Double Dispose() of ZipWritingStream
• XZ: fix padding issues
• XZ: fix variable-length integers decoding #299
• Zlib: fix Adler32 implementation
• Opening 7zip archive with invalid win32 date

Fixes

• Fixed bug: Passing default ReaderOptions when creating ZipReader for solid extraction

New

• Breaking change - Remove ArchiveEncoding static class in favor of instance on Options - ArchiveEncoding is now on the Options base class. This now allows for more Encoding class options as well as a custom Func for decoding for more custom options. Being instance based avoids multi-threading issues. See https://github.com/adamhathcock/sharpcompress/blob/master/src/SharpCompress/Common/ArchiveEncoding.cs

Fixes

• LeaveStreamOpen doesn't work with TarWriter
• If Zip file has normal file header AND a post-descriptor header AND the file is attempted to be skipped by a ZipReader, then the data is attempted to be skipped twice.
• AbstractReader.Skip() does not fully read bytes from non-local streams
