WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Older WordPress updates?, by Samuel Wood (Otto) Only security fixes are backported to older versions. The fixes in 4.9.3/4.9.4 were not security related, but bug fixes only. Those generally are not backported. We recommend only running the latest version of WordPress. Security fixes are backported in an effort to keep the web as a whole safe and secure, however old versions are unsupported and can stop receiving updates at any time. In fact, it is quite likely that we’ll stop updating older disused versions like 3.7 soon. Reply To: Older WordPress updates?
