Entries are ordered by the order the cherry-picks landed on the branch, matching the convention used for 3.47.4.

### Intentionally excluded

Two commits also landed in this range but are routine release infrastructure, not user-facing cherry-picks:

- [#192875](https://github.com/flutter/flutter/pull/192875) Update Flutter DEPS to Dart `b530c21f7de367b94fb04787bfed9d8e989d75e8`
- [#192894](https://github.com/flutter/flutter/pull/192894) Sync `engine.version` to `af7e796e161ae0bb1ff0758c71a7105418bd9ded`

This matches every prior hotfix in this series: the 3.47.1, 3.47.2, and 3.47.3 ranges each contained a Dart DEPS roll and an `engine.version` sync, and none were listed as changelog bullets.

### Note for the release manager

The `Issue Link` on [#192295](https://github.com/flutter/flutter/pull/192295) points at [#189507](https://github.com/flutter/flutter/pull/189507) ("Bump devtools_shared to 13.1.0", merged 2026-07-23), which does not appear to relate to the `package:dds` 5.4.0 roll that PR actually performs. The authored changelog text has been preserved verbatim rather than silently corrected. If that reference is wrong, the bullet should be repointed before this lands.

### Verification

- All three entry links return HTTP 200.
- The `3.47.5` tag link currently 404s because the release has not been tagged yet; it will resolve once "Push release with MPA" completes. This is expected, since the checklist places "Add changelog for stable release" before the release is pushed.

I have double checked with @bkonyi that there is no issue for the dds change because the issue when discovered was already fixed on master.
