v0.43.0

Changed

• Cache::flush(string $query = '') takes the find() query over path, user and tree. flush('tree=.') clears the page, every page above it and everything below it, flush('path=blog/post') one page, and flush("user={$uuid}") one visitor's entries on every page. . is the handle's own page and tree= is the whole store. With no query it clears the page's own rows, or every row of an app store.
• tree on an app store, or an unknown field, throws before anything is deleted.
• The cache.flush:after scope argument is the query, or all and /{path} when none was given.
• Query::compare() is public.

Removed

• Cache::flushTree() and Cache::flushUser().

Upgrading

• Replace ->flushTree() with ->flush('tree=.') and ->flushUser($uuid) with ->flush("user={$uuid}").
