Version 220.127.116.11 (07/27/2020) adjusts how we handle early cache eviction.
Previously, we'd have to evict far too much cached content whenever we needed to evict a cache early, which meant that we rarely did it.
We're now evicting only the exact content that needs evicting.
This means that in a future update we can implement a lot more on-demand cache eviction, which will help the site feel more responsive.
An example of this is when editing a post. Currently after editing, it'll immediately show as edited, but if you refresh the page, it'll likely show the cached, pre-edit version of the post for up to 60 seconds. In this situation, it'd be best to evict that cache on-demand so that those edits are reflected immediately.
