Question: There are still lot of transients we are using in our code, they are around 20. Can I update them all?

[DevinWalker]

Shouldn't this also check if the transient is expired?

[ravinderk]

@DevinWalker I designed different model on how cached value store in DB with a timestamp and I am removing all cache without checking expiration to upgrade every cache value.

@ravinderk yes, please update all transients to use the new class.

Please update all transient usage throughout Give core to use new caching class. :)
