MimeKitLite 3.0.0
MimeKit is an Open Source library for creating and parsing MIME messages. It also supports parsing of Unix mbox files.
Unlike any other .NET MIME parser, MimeKit's parser does not need to parse string input nor does it use a TextReader. Instead, it parses raw byte streams, thus allowing it to better support undeclared 8bit text in headers as well as message bodies. It also means that MimeKit's parser is significantly faster than other .NET MIME parsers.
MimeKit's parser also uses a real tokenizer when parsing the headers rather than regex or string.Split() like most other .NET MIME parsers. This means that MimeKit is much more RFC-compliant than any other .NET MIME parser out there, including the commercial implementations.
In addition to having a far superior parser implementation, MimeKit's object tree is not a derivative of System.Net.Mail objects and thus does not suffer from System.Net.Mail's limitations.

No packages depend on MimeKitLite.
* Removed APIs marked as [Obsolete] in 2.x.
* Lazy-load headers on MimeMessage and MimeEntity (and subclasses) to improve performance.
* Added a new MimeReader class that acts as a lower-level MimeParser alternative, allowing developers to parse MIME content without having to instantiate a MIME tree of objects or wait until the parser has completed (and returned a MimeMessage or MimeEntity object) before processing MIME data. This is conceptually similar to a SAX XML parser approach.
* Added a new ExperimentalMimeParser that duplicates MimeParser functionality, but is built on top of MimeReader. This implementation will eventually replace MimeParser once I get some feedback on it. Should be ~5% faster than MimeParser.
* Improved MimeParser performance slightly based on some of the experimentation done to make the ExperimentalMimeParser fast.
* Added CancellationToken arguments for some AttachmentCollection.Add() overloads.
* Use 'net5.0' as the .NET 5.0 target framework moniker instead of 'net50'. (issue #720)
* Drop support for net45 and replace it with net452.
* Added new MimeMessage.GetRecipients() method.
* MimeMessage and MimeEntity now implement IDisposable. (issue #732)
