Bumps reactor-core from 3.4.24 to 3.5.0.

Release notes

v3.5.0
Reactor-Core 3.5.0 is part of 2022.0.0 Release Train.

This is the first GA release of 2022.0.0 🎉

This note focuses on 3.5.0 proper, curating changes from across all milestones and also includes changes already released as part of 3.4.x line up to 3.4.25.

While there are plenty of improvements and bug fixes, it's worth to highlight the bigger themes first:

The Mono stack is now more lazy and complies to the Reactive Streams specification by only evaluating the source Publisher after receiving appropriate demand. Previously this usually happened during subscription time.

We reworked the metrics utilities. Please consult the reference documentation for more details.

A new context-propagation library has become an important part of the Reactor and Micrometer backbone to allow bridging between reactive and ThreadLocal contextual metadata. Reactor supports this bridging as soon as context-propagation library is present at runtime. Read more in the reference documentation.

Please pay special attention to the following update considerations. More detailed listing of features, bug fixes, and improvements follow.

⚠️ Update considerations and deprecations
⚠️ 🗑️ Removals

Remove Kotlin extensions by @simonbasle in #2949

These now live in the reactor-kotlin-extensions library

Remove deprecated Mono.doOn/AfterSuccessOrError by @simonbasle in #2954

The doOn* recommended alternatives include doOnNext(Consumer), doOnError(Consumer), doOnTerminate(Runnable), and doOnSuccess(Consumer),

The doAfter* recommended alternatives are doAfterTerminate(Runnable) and doFinally(Consumer).

Remove deprecated context-related operators by @simonbasle in #2953

deferWithContext(Function) -> use deferContextual(Function) instead,

subscriberContext(Context) and subscriberContext(Function) -> use writeContext(ContextView) and writeContext(Function) instead,

Signal::getContext() -> use Signal::getContextView() instead,

Context::putAll(Context) -> use Context::putAll(ContextView) instead.

Remove deprecated ElasticScheduler by @simonbasle in #2955

Use BoundedElasticScheduler (Schedulers.boundedElastic()) instead.

⚠️ ⌛ Deprecations

Introduce new module reactor-core-micrometer by @simonbasle in #3015

We introduced a new module, reactor-core-micrometer, and added operators and features supporting the new Observation API of Micrometer 1.10.0, read more about it the release notes.

The class reactor.util.Metrics, Flux::metrics() and Mono::metrics() operators have been deprecated.

Deprecate [Flux|Mono|Synchronous]Sink currentContext by @simonbasle in #2974, #3021

contextView() should be used instead.

Deprecate scheduler start by @chemicL in #3236

Scheduler#init() method should be used instead. Restart capability is discouraged and the new method is allowed to throw in case of initializing a disposed instance. Please create a new Scheduler instance when necessary.

Implementors of Scheduler should also implement the init() method, which currently delegates to start() in the default implementation.

⚠️ ♻️ Behavior Changes

Make some Mono sources and aggregators lazier by @OlegDokuka in #3081

Change behavior of switchOnNext/switchMap default 0 prefetch by @simonbasle in #2956

Have concatMap default to 0 prefetch behavior by @simonbasle in #2967

take(n) now behaves as take(n,true)/limitRequest by @simonbasle in #2969

SourceException wrapper for main stream errors delivered to windows by @chemicL in #3167

Scheduler.isDisposed() only true for disposed instances by @chemicL in #3243

adds cancellation of the source future support by @OlegDokuka in #3146

Scannable.tags() rework, add tagsDeduplicated() by @simonbasle in #3037

Disable fusion in MonoSubscriber by @UgiR in #3245
