Hi @res0nance would you mind take a look and approve/merge?
We are trying to add new m8 instance types.
Let me know if this is the right way to proceed. Thanks!

Looks good to me! I cross-checked the instance types against the AWS instance type names and they appear to be correct.

Hi!
We are looking forward to using these instance types on Jenkins.
Could you share when we can expect it to be released?
Thanks!

[res0nance]

Does updating your aws-sdk not bring the latest instance types?

[eukazakov]

I don't see any updates for the aws-sdk for Jenkins
we have the next versions
Amazon EC2Version 2049.v127f0f109c29
Amazon Web Services SDK 2 :: EC2Version 2.42.33-70.vd69c0763fa_60

[res0nance]

We should not have to add to this list https://github.com/jenkinsci/ec2-plugin/pull/1065/changes#r2023225515

[eukazakov]

then what should we do to access these m8a instance types on Jenkins?
we don't have them in the list atm

[peterzhuamazon]

Yes @res0nance since we are not familiar with this plugin, I have same question as @eukazakov . What should we do to access newer instance types like m8. Thanks.

[peterzhuamazon]

Hi @res0nance is the any update here?
Or could you help suggest how to actually enable m8 instances without this change on existing EC2 Plugin release?

Thanks!
