Changes between Version 1 and Version 2 of Ticket #58919, comment 5

v1	v2
3	3	My uncertainties are:
4	4	- How to organize the built-in caching: Where the functions should be added, where the add_filter and add_actions calls are, and what the functions are named.
	5	- The cache group to be used.
5	6	- The invalidation strategy - I store a list of paths in another cache key, so we can retrieve them later when invalidating. Is there a better way to do this?
6	7	- The invalidation strategy - I do it on all upgrader_process_complete events without checking the parameters. It seems safest and there shouldn't be much of a downside since I assume these events don't happen too often.
