Subject Re: [Camel 3 discussion] Components releases
Date Wed, 20 Feb 2013 02:34:39 GMT
It's hard to track all the version of camel-component and it will make the release process
every complex, if we don't release it with the core. So I cannot agree with this proposal.

As you know In ServiceMix we have lots components which have not direct dependency with the
core, so we break this components out and release them separately. Before we do the servicemix
release, we need to release the kernel ( which is Karaf now), bundles, components, features.
Because the Apache 3 days release vote policy, a whole release will take for weeks. It holds
the release for years, and we can see ServiceMix can barely do one major release per year.

In Camel we provides the patch release after the major release, I think it is not a big deal
if we need to meet the needs of camel component release. BTW, the patch release is also slow
down the trunk development, as it is time consuming work that we need to merge back the patch
to assume it works in different branch.
