+# Scala 2.13.17 (DRAFT)
+
+The Scala team at Akka is pleased to announce Scala 2.13.17.
+
+This release is compatible with the new JDK 25 LTS.
+
+The following are highlights of this release:
+
+### Compatibility
+
+* JDK 25 support in optimizer ([#11046](https://github.com/scala/scala/pull/11046))
+* Support Scala 3.7 in the TASTy reader ([#11100](https://github.com/scala/scala/pull/11100))
+* When parsing Java sources, skip JDK 21+’s JEP 445 compact compilation units ([#11066](https://github.com/scala/scala/pull/11066))
+
+### Breaking changes
+
+* Mix in the `productPrefix` hash statically in case class `hashCode` ([#11023](https://github.com/scala/scala/pull/11023))
+    * The synthetic `hashCode` method of a case class no longer calls `productPrefix`. This changes the hash code of case classes that override `productPrefix`.
+* Improve `scala.util.Using` suppression order (`NonFatal` suppresses `ControlThrowable`) ([#11000](https://github.com/scala/scala/pull/11000) by [@NthPortal](https://github.com/NthPortal))
+    * When multiple exceptions are thrown, a predefined order determines which exception is rethrown and which is attached as "suppressed"
+    * Users of scala-collection-compat can upgrade to [2.14.0](https://github.com/scala/scala-collection-compat/releases/tag/v2.14.0) to get the same behavior change
+    * If you use `Using` in a project that crossbuilds to Scala 3, you may wish to wait for a Scala 3 release that includes the 2.13.17 standard library, or use a dependency override to force the upgrade in your build
+
+### Features and notable changes
+
+* Fix `AnnotationInfo` when using named/default arguments, support custom annotation subclasses ([#10976](https://github.com/scala/scala/pull/10976))
+    * Users can now define, for example, `class nodep extends annotation.nowarn("cat=deprecation")` and use `@nodep` to silence deprecations
+* Show `nowarn`/`-Wconf` filters for a warning with `@nowarn("verbose")` ([#10985](https://github.com/scala/scala/pull/10985))
+* Use `toVector` for XML literal sequences ([#11065](https://github.com/scala/scala/pull/11065))
+
+### Scala 3 compatibility and migration
+
+* Allow using `-Xsource-features` without `-Xsource:3` ([#11123](https://github.com/scala/scala/pull/11123))
+* Lint inferred structural types ([#10942](https://github.com/scala/scala/pull/10942))
+* Port `summonIgnoring` from 3.7 as `c.inferImplicitValueIgnoring` ([#11068](https://github.com/scala/scala/pull/11068) by [@MateuszKubuszok](https://github.com/MateuszKubuszok))
+
+### Notable bug fixes
+
+* Allow optimizer use within Bazel (don't attempt inlining methods without instructions) ([#11016](https://github.com/scala/scala/pull/11016))
+* Reduce memory footprint of evaluated elements in LazyList ([#10937](https://github.com/scala/scala/pull/10937))
+* Deregister stale callbacks in `Future.firstCompletedOf` (prevents memory leaks) ([#10927](https://github.com/scala/scala/pull/10927))
+* Require `-Xsource-features:eta-expand-always` for eta-expansion without an expected type ([#10907](https://github.com/scala/scala/pull/10907) by [@som-snytt](https://github.com/som-snytt))

+
+## Compatibility
+

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