 - Extra currency dictionary is not counted in the account size and does not affect storage fees.

+### Anycast addresses and address rewrite
+- Anycast addresses are not allowed in `dest` of internal and external messages.
+- `addr_var` are not allowed in `dest` of external messages.
+  - Note: as before, `addr_var` in `dest` of internal messages are automatically replaced with `addr_std`.
+- TVM instructions `LDMSGADDR(Q)`, `PARSEMSGADDR(Q)`, `REWRITESTDADDR(Q)`, `REWRITEVARADDR(Q)` no more support anycast addresses and `addr_var`.
+- `addr:MsgAddressInt` in `Account` cannot be an anycast address.
+  - Therefore, `src` of outbound messages cannot be an anycast address.
+  - Existing accounts with anycast addresses change to non-anycast addresses in the first transaction.
+- When deploying an account with `fixed_prefix_length` in `StateInit` of the message (it was called `split_depth` before), the first `fixed_prefix_length` bits of the address are not compared against the state hash.
+  - This allows deploying an account to an arbitrary shard regardless of the hash of state init.
+  - `fixed_prefix_length` remains in the account state.
+  - `fixed_prefix_length` of the account can be at most 8. The limit can be changed in size limits config (`ConfigParam 43`).

 ### TVM changes
 - `SENDMSG` calculates messages size and fees without extra currencies, uses new +64 and +128 mode behavior.
   - `SENDMSG` does not check the number of extra currencies.
+- `LDMSGADDR(Q)`, `PARSEMSGADDR(Q)`, `REWRITESTDADDR(Q)`, `REWRITEVARADDR(Q)` no more support anycast addresses and `addr_var`.
