Thaazhu Update Lock is a lightweight, <a href="https://projektisle.com/pi-plugins/thaazhu-update-lock/" rel="nofollow ugc">developer-focused</a> utility designed to give you absolute control over the WordPress update cycle. While WordPress provides a native way to toggle auto-updates, it lacks the ability to hard-lock a specific plugin version to prevent manual accidental updates or bulk-action overrides.
At its core, Thaazhu (a Malayalam word meaning “lock”) acts as a safety “clasp” for your site’s plugin updates. It allows administrators to freeze a plugin at its current version, ensuring that a critical environment remains stable until you are ready to perform testing and deployment.
Key Features: 
* Granular Version Control: Pick and choose which specific plugins stay frozen. 
* Contextual Documentation: Pair locks with notes to explain technical reasons for the restriction. 
* Modular Architecture: Built for performance without database bloat. 
* Bulk Update Protection: Locked plugins are disabled from bulk actions.
<h3>Usage</h3>
<ol>
<li>Go to Plugins page</li>
<li>Find plugin you want to lock</li>
<li>Click “Lock Update” link</li>
<li>(Optional) Click “Add Note” to explain why it’s locked</li>
</ol>
