+A little over a year ago we updated our default Wireguard image to no longer support building the Wireguard kernel modules and moved that functionality to the `legacy` tag. We did this on the basis that most users were running a kernel that already had built-in Wireguard support (5.6 or above in terms of official kernel releases) and this allowed us to reduce the size of the default image by 600Mb for them.
+
+Revisiting the situation now we see that the vast majority of users are now either running a kernel with built-in Wireguard support *or* a custom kernel, such as on a VPS or NAS, which we have never supported building for. As a result we have decided to deprecate the `legacy` tag from the end of 2024.
+
+In practice this means there's only one case where there will be a still-supported kernel version that doesn't have built-in Wireguard support: 4.19, which goes EOL at the end of 2025. Our stats show a tiny handful of users that this applies to.
+
+If you are still running a 4.19 kernel, or are running any other EOL pre-5.6 kernel, and for whatever reason cannot upgrade then your only option will be to build the Wireguard kernel modules *on the host*, which the default image (using the `latest` tag) will then be able to make use of.
+
+We will provide additional reminders of this deprecation towards the end of the year.
