+# General Support
+
+We will try to align our support strategy with the supported platforms original support policy, in practice this means
+that if the Java Development Kit provides support only to version X and newer, we will align our support practices with it.
+
+Unless decided otherwise by our case-by-case analysis, we will adhere to the following principles:
+
+* We provide support for the current and two previous major versions of our SDKs.
+* We will provide bug fixes and security patches for older versions of our SDKs on a case-by-case basis.
+* We will provide support for versions of our SDKs with the first major version being released a year ago or not older
+  than two major versions.
+
+## Extraordinary Circumstances
+
+In extraordinary circumstances, we may provide support for older versions of our SDKs.
+Examples of extraordinary circumstances include:
+
+* A critical security vulnerability that affects an older version of our SDK.
+* A major change in the underlying platform that requires us to update an older version of our SDK.
+
+We will evaluate requests for support in extraordinary circumstances on a case-by-case basis.
+
+## Enforcement
+
+We will enforce this policy unless a situation is extraordinary.
+
+If we determine that a situation is extraordinary, we will provide support for the older version of our SDK for a limited time.
+
+We will communicate the end of support for the older version of our SDK to users in advance.
