v2.4.3

This is a maintenance release for the 2.4 series which addresses and is fully backwards compatible with previous releases.

This release is built for Scala 2.12, 2.13, 0.26.0-RC1 and Scala.js 1.1.1. Scala.js 0.6 support has been dropped now that it is EOL.

Notable changes:

• Dotty support! (#1973 #1960 #1943)
• Fixed a bug in TLSSocket#readN which could return more than requested number of bytes (#1989)
• Added Pull.extendScopeTo to simplify common usage pattern with http4s (#1996)
• Added withFilter to Stream to allow use in for-comprehensions (#1971)
• Optimized Chunk#traverse (#1952 #1957)
• Optimized UTF8 decoding (#1948)
• Added Stream#evalMapFilter (#1933)
• Added ArraySeq support (#1905 #1899)
• Added cats.Defer instance for Stream (#1936)

There were a number of internal code improvements which pave the way for cats-effect 3 support. Additionally, the test suite was ported from ScalaTest to MUnit with its cats effect integration and scalacheck-effect integration.

Note: this version depends on cats 2.2.0-RC3.
