ESP-IDF 5.0 memory partition table requirements

[some_engineer]

Hey all,

I have a project that is in ESP-IDF 4.4.3 currently.
It is very likely that I will have to migrate it to ESP-IDF 5.0 when the product is already released (FW is upgradeable over WIFI OTA mechanism).
Probably once i migrate to ESP-IDF 5.0 I will have to add Bluetooth features (so adding NimBLE to the project) as well as pre-encrypted FW upgrade feature (available only in 5.0)

I am guessing that I should keep my phy_init partition larger for the bluetooth stuff, but does anyone know how much it requires?
Does ESP-IDF 5.0 require some additional space in other paritions (like default nvs partition) ?
And does pre-encrypted image require some flash partition / bootloader modifications ? (As far as i understood from documentation, it doesn't ).

Many thanks
