+## 0.53.1
+
+This is a bug fix release addressing the following issues:
+
+### Runtime, Tooling, SDK
+- plugins/logs: Previously while passing the decision log plugins's status to the Status API, the plugin held the mutex while a status upload was in process. This had the potential to block new decisions from being written to the plugin's buffer. To avoid this situation, a local copy of plugin's status is created ([#5966](https://github.com/open-policy-agent/opa/pull/5966)) authored by @ashutosh-narkar
+- download: Public docker repositories require an authorization handshake where the client needs to respond to challenges marked by the `WWW-Authenticate` header of a `401 Unauthorized` response. Errors were returned when downloading a public image as it was assumed that authorization is not necessary for public repositories. This fix addresses this issue by challenging any `401 Unauthorized` responses by passing it to the docker.Authorizer ([#5902](https://github.com/open-policy-agent/opa/issues/5902)) authored by @DerGut
+- `opa fmt`: Fix panic encountered while processing policies with comprehensions written on multiple lines with comments in these lines ([#5798](https://github.com/open-policy-agent/opa/issues/5798)) authored by @Trolloldem
+
+### Topdown and Rego
+- built-in function `object.subset`: Fix an issue in `object.subset` related to incorrect results being generated when arrays are provided as an input ([#5968](https://github.com/open-policy-agent/opa/issues/5968)) authored by @DCRUNNN
+- planner: Fix the optimization check for overlapping ref rules ([#5964](https://github.com/open-policy-agent/opa/issues/5964)) authored by @srenatus
