Hook struct member renaming

Hi, while trying to adapt ida_kcpp to ida 8.4 (and next to ida 9.0) we figured that ida_idp.IDB_Hooks.renaming_struc_member was removed at some point.
I’ve looked into the porting guide and seen that the suggested alternative is local_types_changed. I’m not sure how can I understand from its arguments (a) which local type/struct member has changed. (b) there the change is a renaming.

I would be glad to get some help here, please.

Best regards,
Uriel.

Hello, we already moved on with this question via our support channel, but I thought to summarize it here for future reference - if someone encounters similar challenges:

For 8.4, comparing old and new types in local_types_changed seems to be the only viable, although not perfect solution. In IDA 8.4 the renaming_struc_member event is only sent for stack frame members.
