+## Version 12.3.0
+
+### Update and Delete operations no longer target all items by default
+
+The **Update Items** and **Delete Items** flow operations previously affected every item in a collection when their targeting parameters were empty or missing. They now return `null` instead of running against the whole collection.
+
+If a flow relied on the previous behavior to update or delete all items, set an explicit query: `{"limit": -1}`.
+
+These operations now also throw an error when both `key` and `query` are defined at the same time, and **Update Items** throws when either parameter is combined with a batch payload. Pass only one targeting method per operation.
+
+### Storage `exists()` throws on connection failures
+
+The storage driver's `exists()` method previously returned `false` for any failure, including connection timeouts and authentication errors. It now throws on these failures so a transient problem is no longer mistaken for a missing object. Extensions and callers that use `exists()` must handle the thrown error.
+
+If you use S3, grant the `s3:ListBucket` permission so the driver can tell a missing object apart from a permission error.
+
+### Image transformation output default raised to 6000px
+
+`ASSETS_TRANSFORM_IMAGE_MAX_OUTPUT_DIMENSION` now defaults to `6000`, up from `3000` in 12.2.0. Transformations that were rejected between these limits are now allowed by default. To keep the previous `3000` limit, set [`ASSETS_TRANSFORM_IMAGE_MAX_OUTPUT_DIMENSION`](/configuration/files) to `3000` explicitly.
+
+### Docker images use the bundled `pm2`
+
+The Docker image now runs the `pm2` version bundled with it. If your custom `CMD` calls `pm2-runtime` directly, route it through `docker-entrypoint.cjs` instead. The startup sequence is unchanged: bootstrap, then `pm2-runtime`.
