If you don’t check your admin panel very often when installing WordPress (perhaps because you prefer to use remote publishing) or want to make sure 
that your clients ‘ WordPress installations are updated, then this plugin is for you. You don’t need to regularly log in to your admin panel, 
subscribe to an RSS feed, or do anything other than install this plugin to receive notifications when WordPress updates, plugins, and themes are released to Telegram messenger.
All you have to do is install the telegram Update Notifier and forget about it until you get a message about the required updates.
To change the Update Notifier Telegram settings, go to the Update Notifier Telegram section in the main settings menu. From there, you can add a unique telegram ID 
that you need to get by writing to the Telegram bot (https://t.me/update_notifier_telegram_bot) . You can also activate update notifications for themes and plugins.

Some server configurations running Pure-FTPd have trouble updating WordPress via FTP. Common error messages when trying to update WordPress or update/install a plugin look like this:
<ul>
<li>Could not copy file.: /wp-admin/css/theme-editor.dev.css</li>
<li>Could not copy file.: /public_html/wp-admin/css/theme-editor.dev.css</li>
<li>Could not copy file.: /…/…/wp-admin/css/theme-editor.dev.css </li>
<li>Could not create file.: /public_html/</li>
</ul>
Each of these cases seem to be related. There is a patch going into WordPress 3.2 that should take care of the issues and the plugin will be obsolete after updating to that version (https://core.trac.wordpress.org/ticket/10913). In the meantime, install and activate this plugin. Updates should work as expected.
