In terms of the experimental packages for CDK v2. Should they remain on 2.7.0-alpha.x to match aws-cdk-lib (rather than updating to current 2.8.0-alpha.x) ?

<https://docs.aws.amazon.com/cdk/v2/guide/migrating-v2.html>

you can upgrade the alpha packages to current. I believe sst probably only depends on `aws-cdk-lib` and not on any `alpha` packages.

Thanks <@U01QS260Z9N> - my question was more to do with the SST requirements for keeping the versions equivalent

Yep, I thought so. sst core doesn’t depend on any alpha packages, you can safely upgrade to the current minor version without any problems.

<@U01JB1UGDV4> no you can’t upgrade, there are some hard dependencies. Just found them.

<@U01JVDKASAC> why do we need to fix the versions for the alpha packages here? As per <https://docs.aws.amazon.com/cdk/v2/guide/migrating-v2.html|this> there’s no need to fix the versions as it has been done <https://github.com/serverless-stack/serverless-stack/blob/68ff1f112b0d2005931bcdfa6aab7008b7407922/packages/resources/package.json|here>.

Hope you were on a different branch. :sweat_smile:

I didn’t test it thoroughly if mismatched `aws-cdk-lib` and alpha package versions play well together. I was under the assumption they didn’t based on cdk v1 experience lol.

&gt; Yeah, it broke when I tried
<@U01JB1UGDV4> did the mismatched version not work for you?

Yeah, didn't make a note of the error but it wouldn't synthesise
