v3.1.0

Supports Cats Effect 3 and built for Scala 2.12, 2.13, and 3 final.

FS2 3.1.0 features new support for Node.js in the fs2-io module, including cross platform APIs for TCP, UDP, TLS, and file management. The fs2.io.file package has been substantially revamped, removing all dependencies on Java APIs, providing a much nicer experience (though binary compatibility with 3.0.x is provided). The biggest change is the introduction of fs2.io.file.Path as an alternative for java.nio.file.Path -- the former has an idiomatic Scala API and works on both the JVM and Node.js. See the Files section of the microsite for some examples.

Features:

• Update fs2.io.net to build for Node.js and JVM (#2453)
• Update fs2.io.file package to build for Node.js and JVM and remove dependencies on Java APIs (#2519)
• Implement unchunks as the inverse of chunks (#2506)

Improvements:

• Improve performance from Stream.fromQueueUnterminated and Stream.fromQueueNoneTerminated by @jordiolivares (#2521)
• Miscellaneous simplifications & optimizations to main stream interpreter (#2480 #2493 #2501 #2507 #2508 #2524)
• Add a Monoid[Chunk] instance (#2470)
• Add text.hex.{encode, decode} (#2477)

Acknowledgments

Special thanks to @armanbilge who implemented all of the Node.js support in fs2-io as well as in a number of downstream libraries!
