Odoo now prevents archiving a contact while it is still linked to an active user, avoiding situations where that user can no longer access important inbox messages. When a user is reactivated, their linked contact is reactivated as well, and deactivating a user now clearly warns that the related contact remains active unless handled separately.

Odoo now avoids saving user sessions for routes that do not require authentication, such as certain system or RPC endpoints. This reduces unnecessary server work and storage activity, improving efficiency without changing the user experience.

This change improves the checkout experience by loading delivery carrier prices automatically after the page is ready, instead of asking shoppers to click to compute each price. It can make shipping costs clearer sooner for stores with a small number of carriers, though it may add background calls to carrier services.

No task, no issue, just to save personnal work

Could be interesting for user with not alot of carrier to load prices
on checkout step 3 instead of showing "click to compute price".

Could never be standard behavior since it would query external carrier
APIs which some user dont want + slow response.

Some user wants to show price, could be interesting to do it once the
page is fully loaded, async call that replace the 'click to compute..'
by the price with a spinner showing something is done
