.NEXT 5.0.0 has been released! The primary goal of the new release is migration to .NET 8 to fully utilize its features such as Generic Math and static abstract interface members. 5.x is not fully backward compatible with 4.x because of breaking changes in the API. Most of changes done in DotNext, DotNext.IO, and DotNext.Unsafe libraries. UDP transport for Raft is completely removed in favor of existing TCP implementation. There is a plan to implement multiplexed TCP connection and Raft sharding. New features:
- Numeric ranges for LINQ. Thanks to Generic Math
- Little-endian and big-endian readers/writer for various buffer types. Again thanks to Generic Math
- UTF-8 formatting support for various buffer types
DotNext.Reflection library is deprecated and no longer maintained.

Major release of version 2.0 is completely finished and contains polished existing and new API. All libraries in .NEXT family are upgraded. Migration guide for 1.x users is here. Please consider that this version is not fully backward compatible with 1.x.
Major version is here for the following reasons:
- .NET Core 3.1 LTS is finally released
- .NET Standard 2.1 contains a lot of new API required for optimizations. The most expected API is asynchronous methods in Stream class. These enhancements are necessary for evolution of .NEXT library. For instance, new DotNext.IO library could not be released without new .NET API.
- ASP.NET Core 2.2 is no longer supported by Microsoft. Therefore, DotNext.AspNetCore.Cluster library of version 1.x relies on unmaintainable platform. Now it is based on ASP.NET Core 3.1 which has long-term support.
What is done in this release:
- Quality-focused changes
- Removed trivial "one-liners" in DotNext library
- Reduced and unified API to work with unmanaged memory in DotNext.Unsafe library
- DotNext.AspNetCore.Cluster migrated to ASP.NET Core 3.1 LTS
- Increased test coverage and fixed bugs
- Additional optimizations of performance in Write-Ahead Log
- Fixed issue #4
- Introduced API for client interaction support described in Chapter 6 of Raft dissertation
- Migration to C# 8 and nullable reference types
- New features
- Introduced DotNext.IO library with unified asynchronous API surface for .NET streams and I/O pipelines. This API provides high-level methods for encoding and decoding of data such as strings and blittable types. In other words, if you want to have BinaryReader or BinaryWriter for pipelines then welcome!

This is the major release of all parts of .NEXT library. Now the version is 1.0.0 and backward compatibility is guaranteed across all 1.x releases. The main motivation of this release is to produce stable API because .NEXT library active using in production code, especially Raft implementation.
.NEXT 1.x is based on .NET Standard 2.0 to keep compatibility with .NET Framework.
- Optimized methods of Memory class
- Extension methods for I/O are introduced. Now you don't need to instantiate BinaryReader or BinaryWriter for high-level parsing of stream content. Encoding and decoding of strings are fully supported. Moreover, these methods are asynchronous in contrast to methods of
BinaryReaderandBinaryWriter.
