+
+With a great level of excitement, on behalf of Apache Camel community, I'm
proud to announce the general availability of **Camel K 2.0**. It's been a long
ride since the beginning of 2023 when we announced the desire to work on an
heavy refactoring in order to introduce new shining features and be able to run
the future **Camel 4** runtimes.
+
+This is the first important milestone reached, and we thought that the work
done so far is already mature to see **general availability**. We'll keep
working on the [roadmap](/blog/2023/02/camel-k-roadmap-2023/) along this year
in order to try to complete as much as we can of what we have planned for 2023.
+
+Let's look at one by one the main new features or updates that Camel K 2.0 is
introducing. We plan to work on more blogs and documentation dedicated to each
of the new features introduced during next months.
+
+# Upgrade from V1
+
+The first concern you may have is about compatibility to Camel K version 1 and
how to upgrade: we have worked to make this process as smooth as possible. We
introduced some important change in the Kubernetes API and we tried to make
this in a backward compatible manner. In particular we have promoted the
`v1alpha1.Kamelet/KameletBinding` API to `v1` as we now feel it's mature enough
and we have renamed the `v1alpha1.KameletBinding` to `v1.Pipe`.
+
+We don't expect you to make any change on the old API though. As for
`Kamelet`, the Kubernetes cluster will take care to automatically upgrade this
(as it's just a change in the versioning).
+
+WARNING: make sure not to downgrade to Camel K version 1 once you have
upgraded to version 2, because there won't be any conversion from `v1` to
`v1alpha1` and it may result in a fatal error.
+
+The old `v1alpha1.KameletBinding` will still be supported in this release in
order to give you the time to make the needed change and move all your
KameletBindings to
[`v1.Pipe`](/camel-k/next/apis/camel-k.html#_camel_apache_org_v1_Pipe). Try to
give priority to this operation because the `v1alpha1` is now deprecated and
will be removed within the next versions of Camel K.
+
+There is no other important concern about the compatibility with the previous
Camel K version. You can follow the [documentation provided for Camel K
upgrade](/camel-k/next/contributing/upgrade.html) as usual.
+
+We suggest to take the opportunity of this major upgrade to detect any usage
of deprecated parameters in the [Camel K API](/camel-k/next/apis/camel-k.html)
and do the switch accordingly.
+
+# Possibility to run any Camel K Runtime
+
+The first important feature we have introduced is the **possibility to run any
Camel K Runtime**, making Camel K 2.0 backward and forward compatible. With
this feature you can use the [Camel
trait](/camel-k/next/traits/camel.html#_configuration) and specify which
runtime version you want to use. As soon as a new version is available (ie,
runtime version 3 which will run Camel 4), then, you can just update that
parameter without the need to upgrade the operator any longer.
+
+By default, Camel K 2.x will use the stable runtime version at the moment of
the release (in this case, Camel K runtime `2.16.0`).
+
+NOTE: You can use any Camel K Runtime version >= `1.17.0`.
+
+# Enterprise grade build system
+
+We have redesigned massively the way we conceive our build in order to
accommodate the need run any Camel K Runtime. We are in general aware that we
need to strengthen the way we build the applications, making sure each customer
can introduce their tooling and have enough possibility to choose how to
perform such a **build in an "enterprise-grade"**. Although we're still working
in progress (more enhancements to come in next milestone), we already have
achieved most of the points we wanted to cover.
+
+## Free Camel K from Runtime
+
+The build process is now partially decoupled from the runtime process. We have
identified the design and we applied it in Camel K version 2. The most
important news was discussed in the chapter above, the enablement of multiple
Camel K runtime.
+
+In order to enable this feature, you will notice that the `CamelCatalog`
Custom Resource is now a dynamic resource which is reconciled by the operator.
It is the one in charge to dynamically create any new runtime catalog required.
This work was a big design change and we're confident it will help use reaching
the longer term goal which is to **onboard any Camel runtime** (main,
springboot, quarkus).
+
+TODO - some more official doc
+
+## Transform the build into a pipeline
+
+We have realized that the concept of an application build is not something
"static". Each user/company has a different approach when building and testing
an application. That's the reason why we have reworked the entire concept of
the build and replace with something more customizable, a **pipeline**.
+
+The first immediate result of this change is that you have available a [simple
Camel K Pipeline technology](/camel-k/next/pipeline/pipeline.html). This one is
thought for those developers and companies which do not require all the major
features of a complete pipeline technology. You may want to use this in order
to provide some post-build process (ie, running a CVE scanning tool) or in
general, execute any tool required by your company deployment process.
+
+## Camel K Tekton tasks
+
+We also know that many companies already adopts some richer **CICD
technology**. For this reason we have introduced the [Camel K Tekton
task](/camel-k/next/pipeline/tekton.html) which we're willing to support in
order to simplify the onboarding of Camel K in Tekton pipeline.
+
+We have chosen to support Tekton because it's one of the most mature and
widespread used CICD technology. However, if you're using any other pipeline
technology it should not be difficult to transform the action we are supporting
in Tekton task with the one required by your pipeline technology.
+
+## More meaningful error messages
+
+We know **troubleshooting a failing application** can be a bit annoying. For
this reason we've added more error conditions and traces that will make this
activity easier. Check it out `Integration`, `IntegrationKit` and `Build`
custom resources conditions in order to understand why some application has
failed.
+
+In particular in the `Build `(which is the main reason why an application
fails) custom resource you will find conditions like the following one which
can give you an immediate pulse of what's going on:
+
+```
+ conditions:
+ - lastTransitionTime: "2023-05-19T09:56:02Z"
+ lastUpdateTime: "2023-05-19T09:56:02Z"

base image: eclipse-temurin:11"}
+ reason: Completed (0)
+ status: "True"
+ type: Container builder succeeded
+```
+
+## Quarkus Native build as a Pod
+
+A Quarkus native build is an important feature that helps you save resources
and give your Java application all the characteristics of a **first class Cloud
Native** citizen. However, AOT compilation is something that requires resources
and time. For this reason, from now on, when you run a Quarkus Native build,
this will be performed with the `Pod` build strategy, which will basically spin
off an external `Pod` to take care of such an heavy operation.
+
+This is a good news, because it will free the operator from the burden of such
an heavy operation. Moreover we introduced some sensible resource configuration
which should be enough for the builder Pod to complete its work without
affecting the stability of the operator.
+
+However, if those are not enough or you still want to customize the builder
Pod resources, we have made available a set of [builder
parameters](/camel-k/next/traits/builder.html) (mainly cpu and memory
resources).
+
+## Run build unprivileged
+
+This is quite an hidden work we've done and it really gave us a lot of trouble
in order to let **Spectrum** and **S2I** builds to run in an unprivileged mode.
However, we've accomplished it and we feel a little safer against any possible
attack from privileged escalation.
+
+NOTE: we haven't (yet) deprecated **Kaniko** and **Buildah** strategy and
these deployment methods require to run with `root` privileges. Make sure to
understand the possible risks involved.
+
+## Build order strategy
+
+Another little interesting feature you have available now is the possibility
to define which is the order of the building strategy. When in
+Camel K 1 you submitted a series of parallel builds, there was no guarantee on
the order of execution. Now you can specify it using the [Builder trait order
strategy parameter](/camel-k/next/traits/builder.html#_configuration).
+
+If you run many builds in parallel you may want to use the `dependencies`
strategy which will take care to smartly create a queue for those builds which
may depend on each other and leverage the incremental build feature.
+
+Our operator is smarter than any AI out there!!

Review Comment:
```suggestion
## Build order strategy
Another interesting feature that is now available to you is the possibility
to define a build order strategy that controls in which order scheduled
integration builds get executed.
In Camel K v1 a series of parallel submitted builds got executed strictly
sequential (only one single build at a time) and there was no guarantee on the
order of build execution.
Now you can specify the order of builds using the [Builder trait order
strategy parameter](/camel-k/next/traits/builder.html#_configuration).
Supported build order strategies are:
- `sequential`: equivalent to the Camel K 1 behavior running only one single
build at a time
- `fifo`: First in first out strategy runs builds as they have been created
and allows builds to run in parallel to each other as long as
`maxRunningBuilds` limit has not been reached.
- `dependencies`: Sophisticated order strategy smartly creating a queue for
those builds which may depend on each other in order to effectively run builds
leveraging the incremental build feature. Allows independent builds to run in
parallel to each other as long as `maxRunningBuilds` limit has not been reached.
You can now choose from these build order strategies to get the best out of
Camel K. Our operator is smarter than any AI out there!!
