12+
This release brings several notable features:
13+
14+
* https://github.com/quarkusio/quarkus/pull/53295[#53295] - JAR tree-shaking to eliminate unused classes
15+

16+
* https://github.com/quarkusio/quarkus/pull/53339[#53339] - Semeru AOT support
17+
* https://github.com/quarkusio/quarkus/pull/51063[#51063] - Support `@Transactional` for Hibernate Reactive
18+

20+
* New snapshot distribution infrastructure
21+

== Update
23+
24+
To update to Quarkus 3.35, we recommend updating to the latest version of the Quarkus CLI and run:
25+
26+
[source,bash]
27+
----
28+
quarkus update
29+
----
30+
31+
Note that `quarkus update` can update your applications from any version of Quarkus (including 2.x) to Quarkus 3.35.
32+
33+
For more information about the adjustments you need to make to your applications, please refer to the https://github.com/quarkusio/quarkus/wiki/Migration-Guide-3.35[Quarkus 3.35 migration guide].
34+
35+
== What's new?
36+
37+
=== JAR tree-shaking
38+
39+
A new experimental `quarkus.package.jar.tree-shake` option enables build-time dependency tree-shaking.
40+
When set to `classes`, Quarkus performs bytecode reachability analysis to identify and exclude unused classes from runtime dependencies, reducing application JAR size.
41+
42+
The analysis traces references through supertypes, annotations, `ServiceLoader` entries, reflective class loading, and more.
43+
44+
As an example, running tree-shaking on the Quarkus CLI removes over 6,000 unreachable classes, saving around 18 MB (39.5%).
45+
46+
This feature supports `fast-jar`, `uber-jar`, `legacy-jar`, and `aot-jar` packaging types.
47+
48+
As mentioned, this new feature is experimental, and feedback is highly welcome!
49+
50+
=== Profile-guided optimization for native builds
51+
52+
You can now opt in to Profile-Guided Optimization (PGO) for native builds by setting `quarkus.native.pgo.enabled=true`.
53+
54+
Note that PGO is a feature of Oracle GraalVM and is not available in GraalVM Community Edition.
55+
56+
When enabled, Quarkus uses your integration tests as the workload to profile the application.
57+
The resulting PGO data is then fed into the native compilation for better runtime performance.
58+
59+
The implementation follows a similar pattern to the Project Leyden AOT support introduced in Quarkus 3.32.
60+
61+
=== Semeru AOT support
62+
63+
Building on the Project Leyden AOT integration from Quarkus 3.32, Quarkus now also supports IBM Semeru's AOT features.
64+
65+
In initial testing on the `rest-json` quickstart with IBM Semeru Runtime Open Edition 25, startup time was cut roughly in half (from ~380 ms down to ~190 ms).
66+
67+
For now, this is limited to building JARs with Semeru AOT, automatic container image building (as available with Leyden) is not yet supported.
68+
69+
=== `@Transactional` for Hibernate Reactive
70+
71+
Quarkus now supports the `@Transactional` annotation for Hibernate Reactive, thanks to a new `quarkus-reactive-transactions` extension.
72+
73+
This means you can use the familiar `@Transactional` annotation on methods that return `Uni`, and the transaction lifecycle (begin, commit, rollback) will be managed within the reactive pipeline.
74+
75+
A few things to keep in mind:
76+
77+
- Only `TxType.REQUIRED` is currently supported.
78+
- Mixing `@Transactional` with `@WithTransaction` or `@WithSessionOnDemand` is not allowed.
79+
- Methods annotated with `@Transactional` are no longer automatically considered `@Blocking`. If your method is blocking but returns `Uni`, you now need an explicit `@Blocking` annotation. See the https://github.com/quarkusio/quarkus/wiki/Migration-Guide-3.35[migration guide] for details.
80+
81+
=== CORS support for the management interface
82+
83+
The management interface now has its own dedicated CORS configuration, allowing you to set CORS policies independently from the main HTTP interface.
84+
85+
=== Testing improvements
86+
87+
The test infrastructure no longer uses System Properties to propagate configuration from Dev Services, Test Resources, and Test Profiles.
88+
This change opens the door for better parallel test execution (which we hope to achieve at some point in the future) and makes the Config system truly immutable.
89+
90+
Tests using `QuarkusDevModeTest`, `QuarkusIntegrationTest`, or `QuarkusMainIntegrationTest` can now declare a `Config` field or method parameter to access the updated configuration.
91+
92+
=== New snapshot distribution
93+
94+
Quarkus snapshots are no longer published to Sonatype, which had reliability issues with the volume of artifacts involved.
95+
Snapshots are now published daily as GitHub Releases in the https://github.com/quarkusio/quarkus-ecosystem-ci/releases[quarkusio/quarkus-ecosystem-ci] repository, with version `999-SNAPSHOT`.
96+
Each release contains a `maven-repo.tar.gz` asset with pre-built Maven artifacts that you can extract into your local Maven repository.
97+
98+
For CI setups, a dedicated https://github.com/quarkusio/install-quarkus-snapshots-action/[GitHub Action] is also available.
99+
100+
More details can be found in the https://github.com/quarkusio/quarkus/blob/main/CONTRIBUTING.md#using-snapshots[Using snapshots] section of the contributing guide.
101+
102+
=== Jackson reflection-free serializers for Quarkus REST
103+
104+
We initially planned to make Jackson reflection-free serializers the default for Quarkus REST in 3.35.
105+
However, thanks to several community members who tested this feature and reported issues, we identified a number of edge cases that still need to be addressed.
106+
We decided to postpone making it the default to 3.36, so that we can fix these issues first.
107+
108+
We are very grateful to everyone who took the time to report problems, your feedback is what makes Quarkus better.
109+
110+
In the meantime, we very much welcome more testing from our community.
111+
You can enable reflection-free serializers by adding the following property to your configuration:
112+
113+
[source,properties]
114+
----
115+
quarkus.rest.jackson.optimization.enable-reflection-free-serializers=true
116+
----
117+
118+
Please report any issues you encounter on https://github.com/quarkusio/quarkus/issues[GitHub].
119+
120+
