DSL-JSON VS jsoniter-scala

I've updated results of benchmarks of 12 JSON parsers for Scala: - AVSystem's scala-commons - Borer - Circe - DSL-JSON - Jackson - jsoniter-scala - Play-JSON, - play-json-jsoniter - Spray-JSON - uPickle - weePickle - zio-json

I suggest looking into jsoniter-scala Macro API it has unique support of both Scala 2 and Scala 3 in a source compatible manner.

Since v2.13.6 release jsoniter-scala dropped support of Java 8: https://github.com/plokhotnyuk/jsoniter-scala/releases/tag/v2.13.6

SWAR (SIMD in register) techniques were used in the last release of jsoniter-scala to speed up parsing and serialization on JVM platforms.

Try jsoniter-scala. It is a library with macros for handy deriving of safe and efficient JSON codecs that has Scala 3 support since v2.12.1

Use jsoniter-scala for handy auto-derive safe and efficient JSON codecs.

Here is a great example of macros migration from Scala 2 to Scala 3 that are source compatible and tested by the same test sources.

Impressive work, although I'll stand by Scala 2 macros being a blocker -- I mean, look at this monster, nearly 3K lines of dense Scala 3 macro code to replicate functionality you already had in Scala 2. For most mortals that would be a gigantic endeavor, although a great learning experience I'm sure :)

BTW, here is a great example of macros migration from Scala 2 to Scala 3.
