@yrong can you open a PR to this for fixing the conflicts?

[yrong]

@claravanstaden @acatangiu It seems #8271 hasn’t been backported to stable2503 yet. Do we want to include it? Some of the types and primitives introduced in that PR are used here.

#8803

[claravanstaden]

@yrong the message reward topups should not be backported to stable-2503. It is available from stable-2506. It still needs to be audited, etc.

[github-actions]

This pull request is amending an existing release. Please proceed with extreme caution,
as to not impact downstream teams that rely on the stability of it. Some things to consider:

• Backports are only for 'patch' or 'minor' changes. No 'major' or other breaking change.
• Should be a legit fix for some bug, not adding tons of new features.
• Must either be already audited or not need an audit.

Emergency Bypass

If you really need to bypass this check: add validate: false to each crate
in the Prdoc where a breaking change is introduced. This will release a new major
version of that crate and all its reverse dependencies and basically break the release.
