+**BREAKING CHANGES**
+
+The legacy methods to define `createTemplateActions` have been replaced with the new native `zod` approaches for defining input and output schemas.
+
+You can migrate actions that look like the following with the below examples:
+
+```ts
+// really old legacy json schema
+createTemplateAction<{ repoUrl: string }, { repoOutput: string }>({
+  id: 'test',
+  schema: {
+    input: {
+      type: 'object'
+      required: ['repoUrl']
+      properties: {
+        repoUrl: {
+          type: 'string',
+          description: 'repository url description'
+        }
+      }
+    }
+  }
+});
+
+// old zod method
+createTemplateAction({
+  id: 'test'
+  schema: {
+    input: {
+      repoUrl: z.string({ description: 'repository url description' })
+    }
+  }
+})
+
+// new method:
+createTemplateAction({
+  id: 'test',
+  schema: {
+    input: {
+      repoUrl: z => z.string({ description: 'repository url description' })
+    }
+  }
+})
+
+// or for more complex zod types like unions
+createTemplateAction({
+  id: 'test',
+  schema: {
+    input: z => z.object({
+      repoUrl: z.string({ description: 'repository url description' })
+    })
+  }
+})
+```
+
+This breaking change also means that `logStream` has been removed entirely from `ActionsContext`, and that the `logger` is now just a `LoggerService` implementation instead. There is no replacement for the `logStream`, if you wish to still keep using a `logStream` we recommend that you create your own stream that writes to `ctx.logger` instead.
