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.
