+preview: Details of what we have done in the Camel 4.5 release.
+---
+
+Apache Camel 4.5 has just been [released](/blog/2024/03/RELEASE-4.5.0/).
+
+This release introduces a set of new features and noticeable improvements that we will cover in this blog post.
+
+## Camel Core
+
+When using Kamelets and/or Rest DSL then Camel will now hide their intermediate routes and only show user routes.
+The number of routes that Camel logs on startup is thus only the number of _user_ routes. This also avoids cluttering
+up the list of routes in monitoring and management tools.
+
+## Camel Main
+
+We added the concept of _profile_ to running Camel standalone or via camel-jbang. For example camel-jbang runs in `dev` profile
+by default, and `camel-main` would run in `prod` profile by default. 
+
+Using profiles allows you to have profile-specific _application.properties_ files, such as `application-dev.properties`
+that can provide environment-specific configuration, for example hostname, username and passwords for connecting to systems.
+To make it quick and easy to have settings for development, and then avoid having to remove those when building for UAT or production.
+
+## Camel JBang
+
+We fixed some issues using Camel JBang with Windows, but we would still like more feedback from Windows users.
+
+Added `/q/info` as HTTP console to show some basic information about the Camel application. 
+
+## Camel Catalog
+
+We now generate more metadata for every Camel release and have added the following information into `camel-catalog`,
+that can be useful for Camel tooling such as Karavan and Kaoto:
+
+- `dev-consoles` - Provides a list of all available developer consoles
+- `transformers` - Provides a list of all cloud event transformers (Camel K pipes)
+- `beans` - Provides a list of all miscellaneous beans such as `AggregationRepository`, `IdempotentRepository` and all the options. (For example to know that Camel offers a Redis idempotent repository).
+
+## Camel Micrometer
+
+Added _context_ level metrics as well, so you have combined metrics for the entire Camel application.
+
+Adjusted the tags in the metrics to be shorter. See the [upgrade guide](/manual/camel-4x-upgrade-guide-4_5.html) for more details.
+
+## OpenAPI v2
+
+Support for OpenAPI v2 (swagger) has been removed. Use OpenAPI v3 spec instead.
+You can use online coverter tools such as: https://converter.swagger.io/
+
+## Miscellaneous
+
+The `camel-spring-rabbitmq` can now automatically bind and create if setting `autoDeclareProducer=true` for the producers as well.
+
+The `camel-yaml-dsl` can now set error handler on the route level as well. Previously you had to do this via route configuration.
+
+The `camel-kafka` has been upgraded to Kafka Client 3.7.
+
+The documentation has many grammar, typo and cosmetic changes.
+
+Upgraded many third-party dependencies to the latest releases at the time of release.
+
+## New Components
+
+We have added some new AI based components and support for wasm and jolokia.  
+
+- `camel-aws-bedrock` - Invoke Model of AWS Bedrock service.
+- `camel-aws-bedrock-agent` - Operate on AWS Bedrock through its Agent.
+- `camel-aws-bedrock-agent-runtime` - Invoke Model of AWS Bedrock Agent Runtime service.
+- `camel-langchain-chat` - LangChain4j Chat component
+- `camel-langchain-embeddings` - LangChain4j Embeddings
+- `camel-milvus` - Perform operations on the Milvus Vector Database.
+- `camel-qdrant` - Perform operations on the Qdrant Vector Database.
+- `camel-wasm` - Call a wasm (web assembly) function.
+- `camel-platform-http-jolokia` - Jolokia plugin for standalone Camel HTTP Platform
+
+## Upgrading
+
+Make sure to read the [upgrade guide](/manual/camel-4x-upgrade-guide-4_5.html) if you are upgrading from a previous Camel version.
+
+If you are upgrading from, for example, 4.0 to 4.4, then make sure to follow the upgrade guides for each release in-between, i.e.
+4.0 -> 4.1, 4.1 -> 4.2, and so forth.
+
+## Release Notes
+
+You can find more information about this release in the list of JIRA tickets resolved in the release:

+
+## Roadmap
+
+The following 4.6 release (non LTS) is planned for May 2024.
