Display last update on plugins page in WordPress backend

[tonikasch]

Hi,

I think it would be awesome that WordPress displayed the date a plugin was last updated in order to manage plugins that are not updated over versions and over several months.

I know that now a notice will appear when a plugin is classified as "not maintained" but I think many plugins take a time before they are classified as such. That is why this proposal of last plugin update.

Happy to offer up my plugin — which shows when a plugin was last updated and even offers a Site Health Check — for use here as I clearly think this is a feature worth spending dev time on. 😉

Thanks @boogah.
Your plugin is the best approach.
I would only lower the trigger from 2 years to 6 months or otherwise add another trigger on a 6-month basis.
Glad you have created a plugin like yours.

I don’t believe that introducing a health check based on the last updated time of plugins is beneficial. Such a security message could unnecessarily alarm users, prompting them to replace plugins and potentially waste hours of their time. The fact that a plugin hasn’t been updated for more than six months does not inherently indicate a security issue.

For example, consider the Hello Dolly plugin, which is included by default in WordPress and hasn’t been updated in 12 months. This would result in every new WordPress user encountering a "security" warning after a fresh installation, which is far from ideal. Imagine setting up WordPress for the first time and being met with a security alert.

Or consider ​https://wordpress.org/plugins/tinymce-advanced/ last updated 7 months ago and 2+ million active installations.

A longer threshold would be more reasonable, in my opinion, however, setting such a threshold could lead users to believe that it applies universally to all plugins, causing them to think it’s acceptable to install a plugin that hasn’t been updated for, say, 18 months, even though this is not a straightforward matter and should be assessed on a case-by-case basis.

It's not a performance issue so removing the keywords.
