Key changes
🔥📖 Protocol's invariant change: value management (#4634);
Important
Previously, on errors, values were always returned to the message source immediately, without any actual notification.
From now on, values can only be transferred with messages — including error replies — making it possible to check how much value was returned in your handle_reply export.
For messages that do not expect a reply, no value will be returned on errors. This mainly affects the reply logic: any value sent with a reply will always reach its destination and be retained there.
🔥📚 Fixed bug with absence of reply in case of program's exit. Extended purpose and usage of error reply codes (#4620).
Note
If a program exits without sending a manual reply, an auto-generated one will be sent to maintain the invariant that all repliable messages receive one.
Userspace
📚 Optimized amount of custom sections produced by opt-wasm in gear-wasm-builder (#4444);
📚 Added query for inheritor of exited program in gtest (#4616);
📚 Added query for inheritor of exited program in gsdk (#4622).
Runtime

Note
The necessary value is deposited from the treasury account on migrations.
