 ## v8.0.1
 
+- Java 17 is now the minimum supported version.
 - We’ve removed the direct constructors for `TenantSecurityClient` and replaced them with a builder-based API. The static TenantSecurityClient.create method is still provided for convenience.
 - TenantSecurityClient now enforces HTTPS connections to the TSP by default. You can opt out of this restriction using the new `TenantSecurityClient.Builder`, using `allowInsecureHttp(true)`. This should only be done in the case of testing.

 A Java client for implementing CMK within a vendor's infrastructure. Makes requests through an
 IronCore Tenant Security Proxy to tenants' KMS/logging infrastructures.
 
+## Requirements
+
+Java 17 or later.
+
+## Getting Started
+
 The [examples](examples/README.md) and [benchmarks](benchmarks/README.md) are a good way to get started.
 
 More extensive documentation about usage is available on our [docs site](https://ironcorelabs.com/docs/customer-managed-keys/tenant-security-client/overview).
