Full Changelog: v2.1.21...v2.1.22

This release brings a few bug fixes and under-the-hood improvements.

The main user-facing change is the deprecation of user-configurable IsFatal. We decided to deprecate this feature as we believe it's not a feature used by many users (if any) and supporting it brings a lot of unnecessary complexity to ZIO's codebase. If your codebase / library is affected by this change, please open an issue with your use-case.

Full Changelog: v2.1.19...v2.1.20

This release fixes a regressions introduced in v2.1.18 where in some cases the finalizers of an application might not run to completion upon receiving an external interruption signal. We highly recommend users on v2.1.18 to update their zio version to v2.1.19 as soon as possible.

In addition, after some lengthy discussions we made the decision to make 2 RuntimeFlags package-private: Interrupt and WindDown. These 2 flags are not meant to be configurable by users and have the potential to break application code when used. This change is binary compatible but not source-compatible, so any users that get a compilation error after upgrading to v2.1.19 due to usage of these flags should simply remove their usages.

Full Changelog: v2.1.18...v2.1.19

This release of ZIO brings several new features, performance optimizations and bug fixes!

Highlights

1. New ZIO.fromFunction and ZIO.fromFunctionZIO methods that allow extracting multiple values from the environment in a single effect (#9819 & #9782)
2. (Scala 3 only) New provideSomeAuto method for ZIO and Spec, which works similarly to provideSome but without having to provide the environment remainder explicitly.
3. New mapChunksEither and mapEitherChunked methods on ZPipeline give users more options in short-cutting errors when processing streams

Full Changelog: v2.1.16...v2.1.17

Highlights

This seemingly small release brings 2 new features to ZIO which library authors can utilize in order to provide a better DX for users. As usually, it also contains a number of optimizations, bug fixes, and it's fully binary and source-compatible with the rest of the v2.x series.

HasNoScope evidence (#9604)

In ZIO, having a Scope as an environment requirement indicates that the effect contains finalizers (e.g., closing an HTTP connection) which need to be handled at some point in the evaluation of the effect or the application's lifetime. In certain cases, we might want to ensure that an effect provided to a method does not contain any finalizers. Starting with this version of ZIO, users / library authors can use the HasNoScope evidence for methods where the environment is generic, e.g.,:

def foo[R, A](f: ZIO[R, Nothing, A)(using HasNoScope[R]) = ???

val f1 = foo(ZIO.succeed("foo")) // compiles
val f2 = foo(ZIO.acquireRelease(ZIO.succeed("foo"))(_ => ZIO.unit)) // fails to compile

Note that this feature is primarily intended for use in libraries such as zio-http where we need to ensure that a user-provided effect does not contain any finalizers.

Generic interfaces for non-empty collections (#9560)

This release introduces the NonEmptySeq type class (which NonEmptyChunk now extends) so that users / library authors can write generic code which requires non-empty collections as arguments.

Full Changelog: v2.1.13...v2.1.14

Highlights

This seemingly small release brings a number of new features and important bugfixes:

1. Adds support for the Junit 5 engine via the new zio-test-junit-engine module #9214.
2. [ScalaJS] Adds support for accessing environment variables via zio.System in JS engines that support it (e.g., NodeJS) #9282.
3. Fixes a bug to an issue some users faced with ZStream.mapZIOPar* methods since v2.1.12 #9312.

As always, this version is fully source and binary compatible with the rest of the v2.x series.
