 - "You miss 100 percent of the chances you don't take. — Wayne Gretzky" — Michael Scott
 
+This release deprecates the `Severity` enum, the `SeverityLevel` type, and the internal `SeverityLevels` array, all from `@sentry/types`. In v7, `Severity` will disappear (in favor of `SeverityLevel`) and `SeverityLevel` and `SeverityLevels` will live in `@sentry/utils`. If you are using any of the three, we encourage you to migrate your usage now, using our [migration guide](./MIGRATION.md#upgrading-from-6.x-to-6.17.x).

 ## 6.17.0
 
-This release contains several internal refactors that help reduce the bundle size of the SDK and help prep for our [upcoming major release](https://github.com/getsentry/sentry-javascript/issues/4240). There are no breaking changes in this patch unless you are using our internal `Dsn` class, which has been removed. We also deprecated a few of our typescript enums and our internal `API` class. We've detailed in our [migration documentation](./MIGRATION.md#upgrading-from-6.x-to-6.17.0) how to update your sdk usage if you are using any of these in your code.

+#### Severity, SeverityLevel, and SeverityLevels
+
+We deprecated the `Severity` enum in `@sentry/types` and it will be removed in the next major release. We recommend using string literals (typed as `SeverityLevel`) to save on bundle size.
+
+`SeverityLevel` and `SeverityLevels` will continue to exist in v7, but they will live in `@sentry/utils` rather than `@sentry/types`. Currently, they live in both, for ease of migration. (`SeverityLevels` isn't included in the examples below because it is only useful internally.)
+
+```js
+// New in 6.17.5:
+import { SeverityLevel } from '@sentry/utils';
+
+const levelA = "error" as SeverityLevel;
+
+const levelB: SeverityLevel = "error"
+
+// Before:
+import { Severity, SeverityLevel } from '@sentry/types';
+
+const levelA = Severity.error;
+
+const levelB: SeverityLevel = "error"
+
 # Upgrading from 4.x to 5.x/6.x
 
 In this version upgrade, there are a few breaking changes. This guide should help you update your code accordingly.
