After installation plugin will check every day if newer version of wordpress is available and if yes, will send email to blog’s admin with notification.

This plugin is a fork of <a href="https://wordpress.org/extend/plugins/update-notifier/" rel="ugc">Update Notifier</a>. This plugin was forked because there seemed to be no further development on the existing plugin and there was no way to contact the original author to ask about taking ownership. WP Updates Notifier has the following improvements over Updates Notifier:
<ul>
<li>Completely rewritten from the ground up using best practises for writing WordPress plugins</li>
<li>Code wrapped in a class so better namespace.</li>
<li>You can set the cron interval, allowing for more frequent checks.</li>
<li>Update checks trigger WordPress internal update check before notification.</li>
<li>Allows you to set the ‘from address’.</li>
<li>Allows you to set multiple ‘to addresses’.</li>
<li>Makes use of the Settings API.</li>
<li>A number of available hooks and filters for advanced users.</li>
<li>Active support and development.</li>
</ul>

WP Updates Notifier

It's ok for theme and plugins notifications, but notification about core updates does't work for more than one year!
This plugin probably won't recieve an update anymore.

Out-of date and not fully working

Sends email to notify you if there are any updates for your WordPress site. Can notify about core, plugin and theme updates.
