Can you support PSR Cache in version 3?

Is your feature request related to a problem? Please describe.
Some other vendor used in my project uses PSR cache in version 3 not in version 2 so there is conflict.

Describe the solution you'd like
Please support PSR Cache in version 3 also.

Describe alternatives you've considered
I've wrote also to that other vendor to support also version 2. But version 3 is newest so should be also supported by Google Auth

Blocking upgrade to PHP8.1 due to this being the only library left that needs 1.0/2.0 and not 3.0.

In our case, this support is blocking us from adopting Firebase as a push notification service, we are up-to-date using PHP 8.1, so our main option is to use the legacy SERVER_KEY authentication mechanism, which is ironic...

IMO droping support for end-of-life PHP version in a new major release (#322) is the best move here, but is a bit worrying the lack of recent progress on the PR, I'm open to help if neccessary.

Running into similar (blocking) issues here, hope this can be resolved soon.

To implement 3.0 is not trivial - we'd have to either drop support for PHP < 8.0 (psr/cache 1.0 is not compatible with 3.0, and 2.0 requires at least PHP 8.0) which isn't going to happen, or create a TypedItem compatibility layer (see #364). In order to support the latter we'd need to drop support for PHP < 7.0, which is something I am willing to do at this point.

Thank you for your feedback.

PHP 5.x has been EOL for a few years now (3yr2mo) so I think dropping support for it would certainly raise the least eyebrows.

[bshaffer]

I've updated the PR so the library has a minimum of PHP 7.1, and uses the TypedItem compatibility layer with psr 3.0.

Please use composer to try this branch out and see if it works for you

composer require google/auth:dev-add-typed-cache-item

This is now released in v1.20.0
