That area of WP Admin only brings up “Featured”, “Popular”, “Recommended” and “Favorites” listings. Why not “New”? I don’t know the answer to that question.
How to find the newest WordPress plugins? You won’t find them if you go to WordPress.org and click on “Plugins” in the top navigation bar. You can find “Beta Plugins” as you go down the page, but nothing “new”.
The URL, which I found by searching with Google, is: https://wordpress.org/plugins/browse/new/. That means there’s a link to that page somewhere, if only in the site map for the website.
It seems like the WordPress.org folks want to track the newest plugins, but it also seems they don’t want us looking at them.
There are a lot of garbage plugins in the repository. I honestly don’t know how they get approved. There are also a lot of outdated and no longer maintained plugins in the repository. Some of them may still be useful but I’m willing to bet most of them aren’t.
Most of the newest plugins aren’t useful to anyone other than a small part of all the WordPress users out there. Some may be useful to more users, but I can’t tell you which are which just by looking at them.
There used to be a website that did almost nothing other than report on new WordPress plugins. For the life of me, I can’t remember the name of the website or the domain name for it.
It won’t do any good for me to report on anything I won’t or can’t use.
