Migration required for early adopters of Toncenter V3

In anticipation of the public release of Toncenter V3, we have made final edits to the V3 API:

— hashes are now in base64 instead of hex;

— methods that returns an array (e.g. /transactions) now return an object with an array {transactions: []};

— _friendly address fields in each object replaced by address_book hashmap;

— transaction.account_state_after_hash and transaction.account_state_before_hash removed;

This latest version of V3 is now on stage.toncenter.com/api/v3 and stage-testnet.toncenter.com/api/v3.

Next week on Monday, Feb 19, 2024, toncenter.com/api/v3 and testnet.toncenter.com/api/v3 will be replaced on this new V3 version. The stage will also remain available.

The current V3 version is backed up at migrate.toncenter.com/api/v3 and migrate-testnet.toncenter.com/api/v3 and will be available for a month.
