This can be used in situations such as configuring different error handling across a set of routes. In previous versions of Camel this was more cumbersome to do, as you would either have to copy the same configuration to a set of routes or rely on global error handling configuration. +Now you can configure a number of route configurations, and then specify on each route which configuration to use (you can use match by ids, wildcards, and regular expression). + +### Reload Routes + +The route reload functionality in Camel is capable of watching a directory folder for file changes, and then automatic trigger reload of the running routes in the Camel application. +This functionality is intended for development purposes, and not for production use. + +You can see the reloading in action from one of the examples such as: https://github.com/apache/camel-examples/tree/master/examples/main-xml + +### Kamelets + +Kamelets is a higher level building blocks that we keep innovating and improve over the coming releases. +For Camel 3.14 we worked on making Kamelets more configurable, and more self-contained. + +A Kamelet is now capable of configuring its own component instances which avoids clashing +with other kamelets or regular components (local beans). This ensures a Kamelet is a _black box_. + +We made using `AggregationStrategy` easier with scripting languages, which allows +for example Kamelets to embed code as the strategy directly in the Kamelet spec file. + +### Health Checks + +Camel components can now provide custom health checks which can be automatic discovered by Camel. + +We added new health checks for route consumers so a consumer can more preciesly +report health status, and in case of errors, then the consumer reports more detailed +information about the cause such as exception, and http status codes etc. + +Camel now also ensures scheduled based consumers, is run at least once during startup +before the health check can be regarded as UP. Previously what could happen is that Camel +would report UP during startup, and then on first run by the consumer, it is causing an +error and then the health check status would soon after be flipped to DOWN. + +There are now also more configurations to fine-tune the health checks such as number of +successive calls before a reporting as either UP or DOWN (flaky checks). + +We will continue to improve health checks in the upcoming releases. + +### JBang + +CamelJBang is used to quickly try and run Camel applications. + +[JBang](https://www.jbang.dev/) makes it very easy to run Java without all the ceremony. +With CamelJBang we made it possible for anyone to quickly try Camel. + +The Camel Karavan Designer uses CamelJBang in its editor that allows you to visually +builder Camel integrations and run them with ease while designing directly from the editor or web-browser. + +### Kafka + +TODO: + +### Salesforce + +The `camel-salesforce` component has had many bug fixes and improvements implemented, +making it more reliable and robust. + +### Cloud component + +The Camel AWS, Azure, Google, and HuaweiCloud components have had various bug fixes and smaller improvements. + +### Quarkus + +The upcoming Camel Quarkus 2.6 release will be upgraded to Camel 3.14. + +### Spring Boot + +We have upgraded to the latest Spring Boot 2.6 release. + +### Better Java 17 support + +Although Java 17 is not officially supported, we did improve a few Camel components to make them work with Java 17. +The official support is Java 11 (primary) and Java 8 (secondary). + +### New components + +This release has a number of new components: + +- `camel-azure-servicebus` - Stream events from or to Azure Event Hubs using AMQP protocol. +- `camel-huaweicloud-imagerecognition` - To identify objects, scenes, and concepts in images on Huawei Cloud +- `camel-huaweicloud-dms` - To integrate with a fully managed, high-performance message queuing service on Huawei Cloud +- `camel-huaweicloud-obs` - To provide stable, secure, efficient, and easy-to-use cloud storage service on Huawei Cloud +- `camel-json-patch` - Transforms JSON using JSON patch (RFC 6902). +- `camel-springdoc-starter` - Springdoc Swagger UI for openapi-java in Spring Boot + +## Upgrading + +Make sure to read the [upgrade guide](/manual/camel-3x-upgrade-guide-3_14.html) if you are upgrading from a previous Camel version. + +## Release Notes + +You can find more information about this release in the with a list of JIRA tickets resolved in the release: + +- [release notes 3.12](/releases/release-3.12.0/) Review comment: I guess we only need 3.14.0 -- This is an automated message from the Apache Git Service.
