The new Zstandard 1.0 compression algorithm, recently open sourced by Facebook, is one of the few compression algorithms that is both faster and more efficient than zlib, the current “reigning standard”, write Facebook engineer Yann Collet and Chip Turner.
Apple has open-sourced its new lossless compression algorithm, LZFSE, introduced last year with iOS 9 and OS X 10.10. According to Apple, LZFE provides the same compression gain as ZLib level 5 while being 2x–3x faster and with higher energy efficiency.
Microsoft has released a beta of a new portable library called Bcl.Compression that adds support for zip archives and compress streams (i.e. deflate and gzip) for the Portable Http Client. Unfortunately it requires a native library so Silverlight and Windows Phone 7.x developers are out of luck.
The ability to use file compression like the venerable ZIP format is very important to many developers. For those developers using.NET, that means dropping to command shell or using a third-party component. With .NET 3.0, there is built-in support for ZIP files, though the implementation is somewhat questionable.
