Scala 2.13.9

The following changes are highlights of this release:
Regression

Library maintainers should avoid publishing libraries using Scala 2.13.9. Please use 2.13.10 instead. 2.13.9 has a regression where binary-incompatible bytecode is emitted for case classes which are 
also value classes (case class ... extends AnyVal).

Scala 2.13.4

Scala 2.13.4:

    Restores default global ExecutionContext to 2.12 behavior
    Improves pattern matching, especially in exhaustivity checking
    Adds experimental support for consuming some libraries built by Scala 3

and more! Details below.
Concurrency

NOTE The following change affects parallelism and performance. If you use scala.concurrent.ExecutionContext.global you may
want to adapt your code. (But note that Akka is unaffected, because it uses its own execution contexts.)

In 2.13.0 we made ExecutionContext.global "opportunistic". This enabled "batching" of nested tasks
to execute on the same thread, avoiding an expensive context switch. That strategy requires
user code to wrap long-running and/or blocking tasks with blocking { ... } to maintain parallel
execution.

For 2.13.4, we restore 2.12's default non-batching behavior, which is safer for arbitrary user code. Users wanting
increased performance may override the default, if they believe their code uses blocking correctly.
We make that choice available via ExecutionContext.opportunistic.

Using ExecutionContext.opportunistic requires a bit of extra boilerplate, made necessary by binary
compatibility constraints on the standard library. Detailed instructions are in
ExecutionContext.global's Scaladoc.

Further detail: #9270/#9296/scala/bug#12089,
Pattern matching

The pattern matcher is now much better at warning you if a match isn't exhaustive.

The following types of matches no longer disable exhaustivity checking:

    guards (case <pattern> if <condition> => ...) #9140
    custom extractors (user-defined unapply or unapplySeq) #9140/#9162
    unsealed types, if you opt in via -Xlint or -Xlint:strict-unsealed-patmat #9140/#9299

Additionally,

    private classes are now treated as if sealed #9211
    singleton types no longer prematurely widen #9209
    tuples are handled properly #9147/#9163/#9147

New warnings reported can be resolved by:

    adding any missing cases
    in the case of complementary guards (e.g. if n > 0 and if n <= 0) by dropping the last guard
    for custom extractors: demarking irrefutable extractors as such, by defining the return type as Some
    for sealed types: marking traits or parent classes sealed, parent classes abstract, and classes final
    explicitly declaring the default case: case x => throw new MatchError(x)

Otherwise, your options for suppressing warnings include:

    annotate the scrutinee with @unchecked, such as (foo: @unchecked) match { ... }
    disable exhaustivity checking in the presence of guards and custom extractors with -Xnon-strict-patmat-analysis
    disable exhaustivity checking of unsealed types with -Xlint:-strict-unsealed-patmat
    use -Wconf to suppress the warnings globally, with e.g. -Wconf:msg=match may not be exhaustive:i

Scala 3 interop

This release enables the Scala 2 compiler to consume some libraries built in Scala 3. #9109/#9293

The new capability is experimental. To enable it, add -Ytasty-reader to your compiler options.

Not all Scala 3 built libraries are supported, because not all Scala 3 features can be supported.
The library author must stay within the supported subset.

For more details and caveats see the blog post Forward Compatibility for the Scala 3 Transition.
Standard library changes

    When compiling on JDK 15, avoid clash with new CharSequence#isEmpty method #9292
        The clash is avoided by making CharSequence wrappers in Predef non-implicit.
        The change is binary compatible, but not source compatible. Call sites may need updating.
    Make LazyList.cons.apply lazier #9095
    Make MapView#values preserve laziness #9090
    Make ListBuffer's iterator fail when the buffer is mutated #9174
    Un-deprecate useful StringOps methods, despite Unicode concerns #9246

Compiler changes

    Allow using classOf with object type (e.g. classOf[Foo.type]) #9279
    Fix back-quoted constructor params with identical prefixes #9008
    Enable range positions (-Yrangepos) by default #9146

Other changes

Some changes that will also ship in 2.12.13 are also included in this release, most notably:

    When compiling on JDK 15, avoid clash with new CharSequence#isEmpty method #9292
        To avoid the clash, implicit was removed from Predef's implicit conversions to SeqCharSequence and ArrayCharSequence.
        This change is binary compatible, but not source compatible. User code may need updating. See PR for details.

For complete 2.13.4 change lists, see all merged PRs and all closed bugs.

As usual for our minor releases, Scala 2.13.4 is binary-compatible with the whole Scala 2.13 series.

Scala 2.13 notes

The release notes for Scala 2.13.0 have important information applicable to the whole 2.13 series.
Obtaining Scala

Scala releases are available through a variety of channels, including (but not limited to):

    Bump the scalaVersion setting in your sbt-based project
    Download a distribution from scala-lang.org
    Obtain JARs via Maven Central

Scala 2.13.2

Scala 2.13.2 has:

    a brand-new Vector implementation
    configurable warnings
    an improved REPL (now JLine 3 based)
    bugfixes and more

Vector

    Rewrite Vector (using "radix-balanced finger tree vectors"), for performance (#8534)

Small vectors are now more compactly represented. Some operations are now drastically faster on large vectors. A few operations may be a little slower.

Kudos to @szeiger for this work.
Configurable warnings

    Add -Wconf flag for configurable warnings, @nowarn annotation for local suppression (#8373)

Note that scala-collection-compat 2.1.6 (or newer) provides @nowarn for cross-built projects (as a no-op on 2.11 and 2.12).

Special thanks to Roman Janusz (@ghik), whose silencer plugin was the basis for this work.
REPL improvements

    REPL: upgrade to JLine 3 (benefits include multi-line editing) (#8036)
    Default true -Yrepl-class-based and -Yuse-magic-imports (#8748)
        -Yrepl-class-based avoids deadlocks
        -Yuse-magic-imports improves performance for long sessions
    Improve REPL display of method types (#8319)

Special thanks to @som-snytt for spearheading the JLine 3 upgrade.

We are tracking JLine-related improvements and regressions here. There some known regressions in some less-vital features and behaviors; we plan to address these in future 2.13.x releases.
Language changes

    Unicode escapes are now ordinary escape sequences (not processed early) (#8282)

Compiler fixes

    Plug many variance holes (in higher-kinded types, refined types, and private inner classes) (#8545)
    Fix variance handling for parameterized type aliases (#8651)
    Exclude universal members (getClass, toString, etc) from root module import (#8541)
    Matching strings makes switches in bytecode (#8451)

Deprecations

    Deprecate eta-expansion, via trailing underscore, of methods with no argument lists (#8836)
    Deprecate nested class shadowing in "override" position (#8705)
    Deprecate numeric conversions that lose precision (e.g., Long to Double) (#8679)
    Deprecate numeric widening of numeric literals which are not representable with Float/Double (#8757)
    Deprecate old-style constructor syntax (#8591)

Improvements from the future

    There is no more -Xsource:2.14, only -Xsource:3 (#8812)
    Allow infix operators at start of line (under -Xsource:3) (#8419)
    Case class copy and apply inherit access modifiers from constructor (under -Xsource:3) (#7702)

Other fixes and improvements

    Un-deprecate default floating point Orderings; issue migration warning instead under -Xmigration (#8721)
    Support macro annotation expansions in -Wmacros:MODE (#8799)
    Scaladoc can now link to Javadoc for the Java standard library for JDK versions 9 and up (overridable with new -jdk-api-doc-base flag) (#8663)
    sys.env now throws on null environment variable (#8579)
    Make the hashcode method ## have no parameter list (instead of a single empty one) (#8814)

This is not a complete list of changes. For that, see all merged PRs and all closed bugs.

2.13.2 also includes the changes in Scala 2.12.11, most notably:

    Make optimizer work on JDK 13+ (#8676).

Compatibility

As usual for our minor releases, Scala 2.13.2 is binary-compatible with the whole Scala 2.13 series.

Upgrading from 2.12? Enable -Xmigration while upgrading to request migration advice from the compiler.
