As announced in the release notes for [Radicle 1.7.0]({% post_url 2026-03-18-radicle-1.7.0 %}),
+ 
that version contains a mitigation for a security vulnerability.
+ 
Due to backward compatibility issues, indirectly related to the mitigation,
+ 
we released [Radicle 1.7.1]({% post_url 2026-03-20-radicle-1.7.1 %}).
+ 
That release restores backward compatibility and also contains the mitigation.
+
+ 
With the knowledge of how 1.7.0 broke backwards compatibility, however, we decided to
+ 
take a slightly more general view on backwards compatibility in light of the security
+ 
vulnerability.
+
+ 
We are currently working on two features (see below) that will be released in version 1.8.0,
+ 
and decided to delay disclosure of the security vulnerability until that release is available,
+ 
at which point this page will be updated.
+
+ 
Radicle 1.8.0 will better protect users, and give them options to increase their level
+ 
of protection further via configuration.
+
+ 
## Downgrade Attack Protection
+
+ 
We are adding protections against downgrade attacks that rely on data that was received per-node,
+ 
rather than requiring all nodes to upgrade in order to stay compatible.
+
+ 
## Configuration of Protection Level
+
+ 
We are working on a configuration option that will allow node operators and users to
+ 
decide how backwards compatible their node should behave.
+ 
That is, a way for node operators to decide for themselves where they stand on an ordinal
+ 
scale that trades off maximal backwards compatiblity and minimal security one end and
+ 
minimal backwards compatibility and maximal security on the other.
+

+ 
We would like to thank you for your patience and your trust as we work on ensuring that the
+ 
Radicle network stays secure.
