+preview: Details of what we have done in the Camel 4.11 release.
+---
+
+Apache Camel 4.11 has just been [released](/blog/2025/04/RELEASE-4.11.0/).
+
+This release introduces a set of new features and noticeable improvements that
we will cover in this blog post.
+
+## Camel Core
+
+The component _verifier extension_ has been deprecated. This functionality has
not been in use for many years,
+and we will start to deprecate more of these un-used features in camel-core
going forward.
+
+### Recipient List, Split and Multicast EIP
+
+In parallel processing mode, you can also enable `synchronous=true` to force
these EIPs to process
+the sub-tasks using the upper bounds of the thread-pool. If using
`synchronous=false` then Camel
+will allow its reactive routing engine to use as many threads as possible,
which may be available
+due to sub-tasks using other thread-pools such as `CompletableFuture.runAsync`
or others.
+
+Setting `synchronous=true` is the same behaviour is in Camel 2 which did not
have the reactive routing engine.
+
+## Camel JBang
+
+Camel JBang now supports running on Eclipse OpenJ9 Java platforms.
+
+Added `camel edit` command to be able to edit source file using a terminal
editor (nano).
+
+Fixed Camel JBang to be able to run on Windows with Quarkus and Spring Boot
runtimes.
+
+The export command has been further hardened to better export using beans that
may trigger initialization code
+that would not work during export phase.
+
+## Camel SQL
+
+The `camel-sql` component now supports for non-named SQL queries to use Map
message body, where the values
+of the Map is used as SQL parameters (in the order they are in the Map, so use
LinkedHashMap).
+
+We have also significantly improved the performance when using SQL batch
insert or updates.
+
+## Camel Telemetry
+
+In this version we're introducing a new abstract component for distributed
telemetry. The `camel-telemetry` component and its concrete implementations
(`camel-telemetrydev`, `camel-opentelemetry2`) will eventually replace
`camel-tracing` components. The rationale is a new design to move all generic
features of the telemetry components into its abstract definition and make it
easier to maintain the implementation in the long term.
+
+As the new component provide a slight different telemetry traces and spans,
we've decided to develop it while keeping the older implementation as well.
However, you're invited already to try this out.
+
+### Camel Observability Services
+
+The observability services component is now using the `camel-opentelemetry2`
instead of `camel-opentelemetry`. This is just a FYI, nothing is expected to be
done on the user side.
+
+## Camel Test
+
+Added `@StubEndpoints` annotation to make it easy to stub a given component,
such as kafka, so you
+can easily write unit tests without having to use Kafka but let it be
_stubbed_ by Camel and act
+as an internal message queue (ala camel-seda).
+
+We have also made it easier to turn off auto-starting specific routes, using
the new `AutoStartupExcludePattern` option (or `@@AutoStartupExclude`
annotation).
+This allows to exclude routes (by pattern) so you can write unit tests and
fully control which routes are included and started in the tests.
+
+## Camel Spring Boot
+
+The `camel-spring-boot` is upgraded to latest Spring Boot 3.4.4 release.
+
+### Platform HTTP Spring Security integration
+
+The Async Camel Spring Boot Platform HTTP now supports
`DelegatingSecurityContextAsyncTaskExecutor` and follows Spring Boot best
practices for security context propagation. This enhancement allows
security-related information, such as the Principal, to be properly maintained
across asynchronous operations.
+Similar to Spring Boot @Async methods, to propagate security related
information, users can just configure a
`DelegatingSecurityContextAsyncTaskExecutor` Bean.
+
+## Miscellaneous
+
+Upgraded many third-party dependencies to the latest releases at the time of
release.
+
+The `camel-bean` component has been improved to better support invoking
methods with varargs parameter.
+
+The file based components (`camel-file`, `camel-ftp`, `camel-azure-files`, and
`camel-smb`) now better support dynamic polling using `poll` or `pollEnrich`
EIPs with dynamic
+computed endpoint, such as `fileName` by using `PollDynamicAware` that is
specially optimized for these use-cases.
+
+The `camel-smb` component now also has the `autoCreate` option to let Camel
automatic create non-existing starting directory.
+
+The `camel-http` component has more improvements in regards to OAuth2 support.
+
+The `camel-micrometer` component has a new `Gauge` which exposes information
about the runtime running the Camel application:
+
+```
+# TYPE app_info gauge
+app_info{camel_context="camel-1",camel_runtime_provider="Spring-Boot",camel_runtime_version="3.4.3",camel_version="4.10.2"}
1
+```
+
+In `camel-kafka` we added the option `topicMustExists` to tell Camel to check
whether a given topic exist or not on startup.
+This can be used to ensure Camel will only consume from existing topics, and
otherwise fail if an expected topic does not exists in the broker.
+
+Added `list` and `map` functions to simple language so you can more easily
create list/map objects.
+
+The `camel-bom` Maven BOM no longer include a hugh google-bom that could cause
builds to be much slower.
+
+## New Components
+
+We have added a few new components:
+
+- `camel-dfdl` - Transforms fixed format data such as EDI message from/to XML
using a Data Format Description Language (DFDL).
+- `ibm-secrets-manager` - Manage secrets in IBM Secrets Manager Service
+- `camel-oauth` - Camel OAuth
+- `camel-opentelemetry2` - Implementation of Camel Opentelemetry based on the
Camel Telemetry spec
