v3.2.1

• Fixed a severe bug in the downloader.

v3.2.0

• Warning: This version uses different format of bytecoind database and walletd caches, they will be upgraded to the new format on a first start of daemons. Prepare for downtime of up to 2 hours depending on your wallet size and computer performance.
• API change: Renamed methods create_send_proof and check_send_proof to create_sendproof and check_sendproof respectively (along with input parameter send_proof that became sendproof).
• Fixed minor bugs found in the beta release.

v3.2.0-beta-20180723

• Warning: This version uses different format of bytecoind database and walletd caches, they will be upgraded to the new format on a first start of daemons. Prepare for downtime of up to 2 hours depending on your wallet size and computer performance.
• Reworked the wallet cache storage to use 3x less space and run 2x faster.
• Intoduced the 'payment queue' which stores and resends all sent transactions until they are successfully confirmed. This fixes issues with sent transactions lost due to chain reorganizations under high loads.
• Changed the logic of the send_transaction method: It never returns an error, its result is always broadcast because all transactions are first stored in the payment queue and later sent for sure.
• Improved the downloader to reduce sync times.
• Made the params argument optional in all JSON RPC calls according to the spec.
• Improved error handling in the create_transaction and send_transaction methods (distinct error codes for common errors).
• Fixed issue when requests to walletd with address is not in the wallet (it now fails with an appopriate error).
• Changed the mechanism of the memory pool size adjustment to give miners more freedom in selecting transactions for including in blocks.
• The walletd command line parameter --backup-wallet is renamed to --backup-wallet-data and now it makes a hot backup of the wallet cache, wallet history, and payment queue in bulk (backward compatibility is maintained).
• Extended the number of bits of the cumulative difficulty parameter (it is now 128 bits).
• Made entering passwords in terminals/consoles invisible on all major platforms.
• Allowed entered passwords to contain Unicode characters on Windows (not recommended though).
• Changed the logic of the create_addresses method when called with at least one existing spend key and without setting creation_timestamp (or setting it to 0). walletd will perform rescan of the whole blockchain in this case.
• Added a better error message when walletd fails to be authenticated at bytecoind.
• Started versioning binary API methods for better detection of changes.

v3.1.1

• Added --backup-blockchain --backup-wallet command-line flags to bytecoind and walletd resp. to hot-copy blockchain and wallet data (wallet file and wallet cache).
• Fixed behavior of the walletd's methods such as get_balance, which until now returned zero balance for addresses not belonging to the opened wallet file.

v3.1.0

• Updated README in the part of linking with boost libraries to prevent using inappropriate versions.
• API change: Renamed field added_bc_transactions to added_raw_transactions in response of the sync_mem_pool method.
• API change: Renamed fields bc_header to raw_header, bc_transactions to raw_transactions in response of the sync_blocks method.
• API addition: Added the get_raw_transaction method to the bytecoind API to get a transaction by its hash.
• API addition: Added the prevent_conflict_with_transactions field to the create_transaction walletd's method to be used by resilient payout queues.
• Speeded up memory pool to handle large transaction load.
• Fixed rare bug in bytecoind when less than possible transactions were included in block for mining during large transaction load.
• Fixed rare bug in bytecoind when cumulative difficulty of the block was calculated incorrectly, leading to increased orphan block percentage. (bytecoind will now perform quickcheck on start once for all exisitng blockchain database, fixing all differences.)
• Fixed rare bug in bytecoind when it stopped accepting new P2P connections or stopped answering API calls under high transaction load.

v3.0.4

• Made early fixes to downloader to prevent long lagging behind.

v3.0.3

• Fixed consensus bug.

v3.0.2

• API change: In create_transaction, spend_address parameter of type string is changed to spend_addresses of type []string. This change is likely to affect only Web wallets developers.
• API change: In sync_mem_pool, added_binary_transactions of type string is changed to added_bc_transactions of type bytecoin::TransactionPrefix. This change breaks compatilibilty between new and old walletd and bytecoind, so make sure they are both the same version.

v3.0.1

• Added walletd option --export-keys to export keys in legacy format (for example, to print on paper and put in a vault).
• Changed logic of how walletd truncates cache in old wallet files: On writable media, it now tries to do that right after opening.
• Fixed wallet state undo logic, which rarely lead to sync crashes/stucks in version 3.0.0.
• Added test wallets for import/export testing.

v3.0.0

• Added HTTPS support between walletd and bytecoind.
• Added generating and checking send proofs.
• Added SQLite database support as an alternative to LMDB.
• Added several legacy bytecoind RPC API methods for miners.
