+#### Changelog {#Changelog-v5.8.1}
+
+##### Fixed
+
+<ul>
+<li>
+<details>
+<summary>Fixed Inconsistent Context Behavior in UDG APIs</summary>
+
+Addressed an issue for UDG APIs where caching led to the forwarding of stale values for headers that contained content variables towards the upstream of the UDG apis.
+</details>
+</li>
+<li>
+<details>
+<summary>Improved Route Matching Logic for API Requests</summary>
+
+Resolved an issue where requests could be routed incorrectly due to inverted prioritisation of dynamically declared paths over those with similar static paths. Now, statically declared paths take priority in the path matching algorithm, so if API1 has listen path `/path/{param}/endpoint` and API2 has listen path `/path/specific/endpoint` a request to `/path/specific/endpoint/resource` will be correctly routed to API2.
+</details>
+</li>
+<li>
+<details>
+<summary>Resolved Issue With Default Enforced Request Timeout</summary>
+
+Fixed an issue where an [enforced timeout]({{< ref "tyk-self-managed#enforced-timeouts" >}}) set for a specific API endpoint could be overruled by the configured [proxy_default_timeout]({{< ref "tyk-oss-gateway/configuration#proxy_default_timeout" >}}). Now if an endpoint-level timeout is set then this will be honoured, regardless of any default timeout that is configured.
+</details>
+</li>
+<li>
+<details>
+<summary>Fixed Issue With Tyk Self-Managed Gateways Claiming Licenses</summary>
+
+Resolved a race condition in self-managed deployments which occasionally lead to fewer Gateways registering with the Dashboard than the number that had been licensed. Now Tyk Self-Managed deployments will allow the licensed number of Gateways to register and serve traffic.
+</details>
+</li>
+<li>
+<details>
+<summary>Resolved merging issue in field-based policy permissions</summary>
+
+Resolved a bug where `allowed_types` from multiple policies were incorrectly merged using intersection logic. Policies now correctly merge fields to allow access to any fields listed across the applied policies.
+</details>
+</li>
+</ul>
