How to upgrade to WordPress 6.4.3

Upgrading your site to WordPress 6.4.3 is a simple process. Users can choose to download the upgrade directly from WordPress.org or, more conveniently, upgrade via the WordPress Dashboard by selecting «Updates» and then «Upgrade Now». For those sites that have automatic background updates, the process should already be underway, demonstrating WordPress’ efficiency in keeping your users’ sites secure without additional effort on your part.

Looking ahead

Version 6.4.3 is a short-cycle release, being a precursor to the next major release, WordPress 6.5, planned for March 2024. This pace of updates reflects WordPress’ commitment to continuous improvement and adaptation to the changing needs of the web and its users.

Attacks and malware prevention

With each new release, WordPress becomes better equipped to deal with the latest tactics and tools used by cybercriminals. From brute force attacks to SQL injections, updates provide the defenses needed to prevent exploitation of your site. By keeping your site up to date, you minimize the risk of malware infections, which can not only affect your site, but also spread to your visitors.

Plugin and theme compatibility and security

Updating WordPress also ensures compatibility with the latest version of plugins and themes, many of which include their own security updates. Using outdated versions of plugins and themes can open up specific vulnerabilities on your site. Therefore, keeping the entire WordPress ecosystem up to date is crucial to ensure a secure and stable environment.

Recommendations before upgrading:

Before installing a WordPress update, it’s important to take certain precautions to ensure the process is as safe and smooth as possible. Here are some key recommendations in the form of bullet points:

• Make a full backup: Make sure you have a recent backup of your site, including files and database, before proceeding with the upgrade.
