The way Odoo loads internal application components has been simplified and made stricter, reducing hidden errors and unpredictable behavior. This improves reliability across several apps and helps ensure issues are detected earlier instead of failing silently.

This update removes or simplifies older compatibility code used by several interface components, reducing maintenance complexity. It should make future updates safer and easier without changing day-to-day user workflows.

Australian BSB bank details are now handled in the core Australian localization instead of only the ABA banking add-on. This makes BSB validation available to more Australian users, even if they do not use ABA payment files.

BSB definition is now moved from enterprise (l10n_au_aba) to l10n_au.

BSB is not limited to ABA bank interactions.

As such, it is useful to define this and allow validation in l10n, making it available to users who are not using ABA files.
