v0.3.0 - Network upgrade release

Note: This release includes a breaking change to the blockchain DB. A node
upgrading to this version will need to delete its existing db and resync
the blockchain.

Important: You do not need to delete your wallet. Fake funds are SAFU.

To reset your database, follow these steps:

1. Stop your node.
2. Locate your Tari data folder. The default locations are ~/.tari on Mac or Linux and %USERPROFILE%\.tari-testnet under Windows.
3. Delete the rincewind/db and rincewind/peer_db folders in their entirety. You can leave dht.db, and the wallet directory intact.
4. Restart your node. Resyncing takes an hour or more right now.

New Features in this release

• Several of back-end changes (hence the need to reset the db) to accommodate pruned mode nodes.
• Several new gRPC endpoints for use by the block explorer (and future wallets) (#1922)
• Increase redundancy for Store and Forward messages (#1929). This PR increases the number of nodes
  that will see and store a SAF message when it reaches the neighbourhood of the destination.
• Have Messaging protocol substreams close after a period of inactivity (#1913)

Bug fixes

• Fix mobile build by emitting cargo:rerun-if-changed directive automatically for protobuf (#1926)
• Fix missing Source and Destination Pubkeys in FFI Transaction Cancellation callback return (#1933)

v0.2.5

v0.2.5 focuses on node stability and network performance

Features

• Added get-state-info command to display current base node state (#1880)
• Message tracking for testnet troubleshooting (#1881)
• Added OSX section to README.md (#1888)
• Add the version command to base node CLI
• Add get_cancelled_transaction_by_id to FFI & update cancel callback
• Adding GetCalcTiming function to grpc service (#1872)

Performance improvements and bug fixes

• Refactor the validators to ensure that each validation step only completes once (#1873).
• Add local pub key to the source and dest fields for cancelled txs in FFI (#1893)
• Switched the BlockEvent stream to Tokio broadcast (#1889). Reduce the memory footprint for block event broadcast
  channel by using a tokio broadcast channel.
• Chain metadata service not updating metadata on reorgs (#1890)
• Update sending of Tx Reply & Finalise msgs to send SAF if Direct fails (#1876)
• Limit unnecessary storage of messages with duplicate content. (#1862)
• Fixed block_forward sync to add blocks via local interface to ensure that events trigger correctly.
• Fixed a typo in mobile build script (#1875)
• Replace deprecated bigint with uint (#1874)

v0.2.4

Improvements

Most improvements in this release are centred around removing redundant network traffic and improving peer-to-peer connectivity.

Some of the changes that have come in since the last release include:

• Introduce temporary short term ban for peers that are providing chain metadata but do not respond to header and block requests.
• The chain synchronisation mechanism is simpler and more robust. Previously it was possible that a node would unfairly ban a peer after an initial chain sync.
• The check_db CLI command does more through checks, including block validation. Previously it was only checking the header chain.
• Old store and forward messages are now removed from the DB after they have been queued to be sent to the destination node.
• Connections are now closed earlier if a peer is banned.
• Deprecated tables and code have been removed from wallet codebase.
• The Store and Forward cache size now has a hard limit.
• Add node version info to PingPong messages. This will help identify if network issues are related to peers running older software.
• Introduce Hamming distance as distance metric. The XOR metric seems to cause clustering of nodes that are not able to communicate. Hamming distance seems to improve the clustering issue. The XOR metric is still the default, though will likely be replaced by the Hamming distance in an upcoming release following further testing.

The Transaction send logic in the wallet has been substantially streamlined:

1. First a Direct send is attempted (previously the direct and SAF were both sent at the same time).
2. A SAF message is only sent if a Discovery needs to be done or the Direct messages fails.
3. A record is made in the DB if a direct send occurs because then we know the recipient DEFINITELY got the message and no repeat or SAF should be sent.
4. If only a SAF message was sent then the Recipient is registered for monitoring by the Liveness service.
5. If a PONG is received then only a Direct send is attempted as a repeat sending of the transaction (so SAF is sent on repeats).
6. As soon as a Direct send is successful no further repeats will be sent.

• Multiplex substream counts have been added - allows the connectivity manager to kill
  dormant connections.

Bug fixes

• Temporarily removed randomx-rs (which was causing illegal instruction crashes on some chipsets).
• Log rollovers were writing to the wrong directory in some cases.
• Don't panic if the logger is initialized twice in the Wallet FFI (#1863)
• A few flaky tests were fixed.

Stability release

This release focuses on network reliability and stability

• Hamming distance calculation added to DHT (XOR metric is still used as
  of now)
• Added helpful message if tor is not started
• Don't require a network for --create-id and --init flags
• Temporary banning of non-responsive nodes
• Dedup cache optimisations
• Cleaner shutdown (stops deluge of error messages we see sometimes)
• Logging improvements
