For deployment only does the sdk version matter?

[Hugo Visser]

Hi,

When deploying an app, does the sdk version you deploy it with (not
compiled with in case of Java) matter? Is it OK to deploy an app using
the 1.5.x API's with an older SDK such as 1.4.x?

I'm asking because I'm setting up an automated deploy and some day I'm
bound to forget to update to the latest sdk on the CI machine :)

Thanks,

Hugo

As far as my knowledge goes, you upload the source code (allowing downloads of it later), and its compiled, precompiled or whatever (Python/Java/Go...) in their machines; so the only problem here is you might be using a feature that has change their behaviour since the version you locally tested it.

Only your version matters. However, it is a good idea to stay somewhat up to date, as some APIs (experimental ones) get deprecated.

One more thing: I tried running a really old application a while ago that was developed using an SDK version that was 1.1.x, and it wouldn't work with the newest SDK.

Thanks Ikai, keeping it somewhat up to date will be fine for CI
purposes.
