SharpZipLib

New patch release that mainly fixes issues with the changes in v1.4.0.

ZIP String Encoding:

Further iteration on the StringCodec API, since the released version was confusing to use and in some cases could not be used without causing deprecation warnings.

• 🐛 #778 zip cleanup/fix of StringCodec by nils måsén

TAR:

Two issues that could cause deadlocks was found in v1.4.0, one due to a typo in the async implementation and one due to a buffer not being cleared.

• 🐛 #791 tar use sync codepath on sync methods by Lars Hanisch

• 🐛 #789 tar clear rest of buffer when eof is reached by nils måsén

Async:

General async speed improvement, since we now correctly opt out of requiring to continue in the same context (ConfigureAwait(false)).

• 🐛 #787 use ConfigureAwait(false) on every await by Lars Hanisch

Other changes (not related to library code):

• 📚 #775 fix circular refs and target fw by nils måsén

This is the first stable release for v1.0

Please see https://github.com/icsharpcode/SharpZipLib/wiki/Release-1.0 for more information.

• Multi-member gzip files are now supported. Contributed by Geoff Hart.
• Zero byte files caused ZipOutputStream to create invalid zipfiles. Contributed by Mark Ritchie.
• ZipFile.CommitUpdate failed on ODT (Open Document) files when updating in memory. Contributed by Dricks.
• Exceptions occurring within ZipFile.CommitUpdate were being silently discarded.
• In FastZip, the NameFilter erroneously removed all escapes from regex. Contributed by John Lemberger. Note: This is a breaking change - if you had detoured this filter bug via doubled-up backslashes, please halve them - for example change @"\\myextract.txt$" to @"\myextract.txt$", or change "\\\\myextract.txt$" to "\\myextract.txt$".
• AES Encryption and Decryption is now supported.
• TarArchive now has IsStreamOwner property, for use with MemoryStream.
• Removed exception "Extra data contains Zip64 information but version 2.0 is not high enough" due to rogue zip creators.
• FastZip.ExtractZip now accepts an Input Stream.
• Zip input and output streams can now specify buffer sizes.
• Solved "NTFS Extra data invalid" exception when reading zip files with zero-length NTFS ExtraData entry.
• Fixed "Size mismatch" exceptions reading zips created by SharpZipLib with an explicit entry CRC and Size.
