If you find it cumbersome to manually check if installed plugins have received updated from the developers this is the plugin for you. Install and activate and you’ll get a simple notification warning you about an old plugin in your installed plugins list.

Plugin Last Updated Warning

This plugin will display a warning for plugins that haven't received updates on the WP.org plugin repo the past year.

LocalDev Switcher allows you to seamlessly toggle between production plugins and their local development versions.
Usage:
<ol>
<li>
Place your local dev version of a plugin in:
wp-content/plugins/localdev-{plugin-slug}
</li>
<li>
You should now have two directories containing the same plugin inside your <code>/plugins/</code>:
<ol>
<li><code>/plugins/your-plugin/</code> – Loaded from VCS/WordPress.org Plugins/etc.</li>
<li><code>/plugins/localdev-your-plugin/</code> – Your local development version</li>
</ol>
</li>
<li>Use LocalDev Switcher to toggle between the version-controlled and local versions. The toggle UI appears in the plugin meta row.</li>
</ol>
LocalDev Switcher prevents double-loading and ensures only the desired version is active.

LocalDev Switcher

Easily switch between version-controlled plugins and local development versions by toggling in the Plugins screen.
