Please add support for Protobuf 5

[filbranden]

Help us help you

Planning a new virtual environment that includes Protobuf 5, more specifically protobuf==5.28.1, I'd like to request that a version of Tink that supports Protobuf 5 would be available

Is your feature request related to a problem?

Not a blocker right now, but planning to migrate applications to the new venv that includes Protobuf 5 and I expect the ones that use Tink will be blocked on this feature

What sort of feature would you like to see?

If support for Protobuf 5 is not backwards compatible, then possibly consider splitting into a new major version e.g. tink==2.0.0 with support for Protobuf 5, keeping a Tink 1.x branch for Protobuf <5 in case it still needs maintenance?

Have you considered any alternative solutions?

Not really, we have at least one app that went all in on Tink so we'd really like to have Tink with Protobuf 5 support available.

Would you like to add additional context?

Using Python 3.12

Thanks!

Hi there, just wanted echo this desire... Is it just a matter of dropping the upper bound constraint?

[calderonth]

Yes please, this is quite problematic for us too when trying to use Tink in projects that rely on protobufs in 5.x, downgrading is not a great option.

I noticed commit f86f602 solving this issue.
@juergw or @morambro - do you plan to cut a new release soon and publish wheels to PyPi?

Hi @mouchar, we are currently working on a new release. We don't have a precise timeline yet, but it should be ready by the end of March.
