+
+It is my pleasure to announce the 1.6.1 bug fix release of MapStruct.
+This release includes 1 enhancement and 8 bug fixes, including some regressions introduced in 1.6.0.
+
+With this release we support the use of the Java 19 `LinkedHashSet` and `LinkedHashMap` factory methods.
+

+
+### LinkedHashSet and LinkedHashMap factory method
+
+With this release if your source code is Java 19 or later MapStruct is going to use the new factory methods when creating a `Set` or `Map`
+
+On Java 18 or earlier it looks like
+
+{{< prettify java >}}
+Map<AuctionDto, AuctionDto> map = new LinkedHashMap<AuctionDto, AuctionDto>( Math.max( (int) ( auctions.size() / .75f ) + 1, 16 ) );
+Set<TargetFoo> set = new LinkedHashSet<TargetFoo>( Math.max( (int) ( foos.size() / .75f ) + 1, 16 ) );
+{{< /prettify >}}
+
+Whereas on Java 19 or later it looks like
+{{< prettify java >}}
+Map<AuctionDto, AuctionDto> map = LinkedHashMap.newLinkedHashMap( auctions.size() );
+Set<TargetFoo> set = LinkedHashSet.newLinkedHashSet( foos.size() );
+{{< /prettify >}}
