I've been stuck on PHP 7.1 for Windows because that's the latest WinCache I could find. I just went looking deeper and eventually found https://forums.iis.net/t/1237884.aspx, which has a link to https://windows.php.net/downloads/pecl/releases/wincache/2.0.0.8/, which has a 7.2 download., and its logs subdirectory has a 7.3. The main is still 7.2, which I'll take.
Then I checked out simple searches. Google and Bing searches for WinCache both havehttps://www.iis.net/downloads/microsoft/wincache-extension at the top of the organic SERP. That page shows 5.*, 7.0, and 7.1, but no later.
Google #2 and Bing #3 is http://php.net/manual/en/book.wincache.php and is old, for PHP 5.
Google #3 and Bing #4 is https://pecl.php.net/package/WinCache, with a 2.0.0.8 link to a 2016 tarball.
Bing #2 and Google #4 is https://sourceforge.net/projects/wincache/, which shows only 7.2.
Then I searched GitHub for WinCache. That found many entries, mostly old. What I thought to be the only recognizable name was php/pecl-caching-wincache, but despite saying updated last year, all of its files are 4-9 years old.
It would be a big help if iis.net, php.net, pecl.php.net, SourceForge, and GitHub all featured the same downloads or links to a single master distribution, and that the top of Google and Bing organic SERPs pointed to good pages.
