- Line 19: Update the documentation sentence in the device-info migration
guidance to use the direct imperative wording “Move integrations to attributes.”
- Line 17: Replace the “2026.X” placeholder in the release statement with the
confirmed exact Home Assistant Core release number before publication; if the
release is not yet confirmed, leave the statement pending rather than asserting
an estimate.
- Line 7: Change the “Summary of changes” heading from level three to level two,
using an H2 heading for the document’s first section.
- Line 39: Update the migration around device_info.name to preserve the prior
missing-field behavior: convert an absent attribute represented by UNDEFINED to
None, or retain device_info.get("name") mapping access. Ensure downstream code
continues receiving None when name is missing.

Use an H2 heading for the first section.
Change ### Summary of changes to ## Summary of changes. The current heading skips a level and triggers MD001.

Replace the release placeholder before publication.
2026.X does not identify a Home Assistant release. As of September 10, 2026, the referenced core pull request is still open, so state the exact target release only after it is confirmed. (github.com)

| Dict-style access still works for now, so your integration keeps running, but it is a compatibility layer which will be deprecated and removed in a later version. Integrations should move to attributes. |

Use a direct migration instruction.
Replace “Integrations should move to attributes” with “Move integrations to attributes.”
As per path instructions, instructional documentation must use a direct and authoritative tone.

Preserve the missing-field behavior in the .get migration.
When name is absent, device_info.get("name") returns None, but device_info.name returns UNDEFINED according to Lines 78-89. This replacement can pass a sentinel to code that expects None. Show an explicit UNDEFINED conversion or retain mapping access during migration. (github.com)
Proposed correction
- name = device_info.name
+ name = device_info.name
+ if name is UNDEFINED:
+ name = None📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
