Versioning structure

I might have missed where this was discussed, but I don’t quite see how the CP directory solves the problem the WP repo has with versioning.

As far as I can tell, the only version the WP API will serve is the one marked as Stable Tag, although the previous versions are available for manual download. What this does is give the users a false sense of being up to date. For WP releases, the update nag is there, but it can be ignored for years. When it is, all the plugin updates are also ignored because the version numbers don’t match.

I’ve heard that CP will keep 1.x working “forever”, so when 2.x and 3.x are out, wouldn’t they need a different set of plugins? And are they all in one directory? Is the latest version of the plugin the only one that is available?

Take a look at Statistics | WordPress.org to see that there are so many versions being run that the repo doesn’t help at least a quarter of them.

Some good questions…

I don’t think this has been discussed much yet.

I don’t follow this part. WordPress/ClassicPress core version is totally separate from plugin versions, and you can update plugins just fine on an older site as long as the plugin is still supported in the older version of core.

The plugin versions and the “stable tag” are another set of version numbers, this time related to the plugin only.

Which versions of WP are supported by a given plugin is yet another set of version numbers, and they have “Requires at least” and “Tested up to” tags in the readme, which makes sense to me. We will probably need to introduce our own tags for these values.

This is what I was talking about. The statistics page shows that not everyone updates WP to the latest version (update nag is ignored), so as the plugins continue to evolve to support the more current releases, their “Requires at least” increases, which means that the API won’t return that plugin as needing an update because the Requires is higher than the site’s WP version. (there is only one plugin version served) This gives the illusion of the plugin being up to date when it is not. The WP API just hides the fact that there is a newer version of the plugin, because it is running on an older WP version.

Newer plugin versions probably use functions that do not exist in older versions of WP, so from that standpoint the behavior is correct.

I’m not questioning the policy, just stating what happens. If the update was indicated, the user might actually update WP to get the plugin update.
With CP, it is already known that the versions will likely be incompatible, so serving only one version of a plugin will be a bad thing.

“likely” is too strong a word to use here - v1 to v2 may break some edge cases, but we won’t be making incompatible changes “just because”.

I think it’s worth emphasising edge cases - there’s nothing planned that should break anything at all.
