| # v4.0 | ||
| ## How to Upgrade | ||
| When upgrading to this version from **hsd v3.x** you must pass `--chain-migrate=3` when you run it for the first time. | ||
| If you are upgrading from **hsd v2.x**, then you also need to pass `--wallet-migrate=1`. | ||
|
|
||
| ## Notable Changes | ||
| ### Urkel Tree Compaction | ||
| `FullNode` parses new configuration option `--compact-tree-on-init` and `--compact-tree-init-interval` which will compact the Urkel Tree when the node first opens, by deleting historical data. It will try to compact it again after `tree-init-interval` has passed. Compaction will keep up to the last 288 blocks worth of tree data on disk (7-8 tree intervals) exposing the node to a similar deep reorganization vulnerability as a chain-pruning node. [#669](https://github.com/handshake-org/hsd/pull/669) | ||
|
|
||
| This feature is disabled by default. Similar to `prune` option of the FullNode, **this will limit the reorganization ability of the node** but will save disk space. Different from `prune`, this does not happen retroactively given the nature of the Urkel Tree, that's why it is called `compaction` which is better term for it. If enabled, compaction will only happen when node starts/restarts. To enable use `--compact-tree-on-init`. | ||
|
|
||
| After compaction next compaction will run after `--compact-tree-init-interval` blocks have passed and it will also only trigger after start/restart. By default it is set to `10 000` blocks. | ||
| Example: `hsd --compact-tree-on-init --compact-tree-init-interval=10000` - this is tree compaction enabled handshake node. | ||
|
|
||
| | Height | Full Tree Size(no reorg) | Compacted Size | | ||
| | ------ | ------------------------ | -------------- | | ||
| | 100 000 | 6.73 GB | 511.37 MB | | ||
| | 105 000 | 8.04 GB | 597.22 MB | | ||
| | 110 000 | 9.89 GB | 727.02 MB | | ||
| | 115 000 | 11.78 GB | 859.22 MB | | ||
| | 120 000 | 13.40 GB | 976.03 MB | | ||
|
|
||
| *Note: Compaction time depends on the compacted size, not the full tree size.* | ||
|
|
||
|
|
||
| ### Node and Chain | ||
| - `FullNode` and `SPVNode` now accept the option `--agent` which **adds** a string to the user-agent of the node (which will already contain hsd version) and is sent to peers in the version packet. Strings must not contain slashes and total user-agent string must be less than 255 characters. [#710](https://github.com/handshake-org/hsd/pull/710) | ||
| - Example: `hsd --agent=example` will give you node with agent: `/hsd:4.0.0-rc.1/example/` | ||
| - Fix SPV node reorg sync issue. SPV will also check `MTP` and `time-too-new`. [#721](https://github.com/handshake-org/hsd/pull/721) | ||
| - `hsd` will critically shutdown on Disk write failure or corruption. `FullNode` and `SPVNode` will emit `abort` event on these failures so embedders can use these events to clean up before shutdown. [#650](https://github.com/handshake-org/hsd/pull/650) | ||
| - `hsd` will recover tree root cache to maintain consistent look up times later for the proof requests. (Making startup time slightly slower) [#726](https://github.com/handshake-org/hsd/pull/726) | ||
| - Checkpoints up to `100000` block. [#734](https://github.com/handshake-org/hsd/pull/734) | ||
| - Fix blockstore atomicity issue, resolves rare **Block not found** issue when process is killed during write. [#688](https://github.com/handshake-org/hsd/pull/688) | ||
| - remove inflation bug softfork covert signaling. [#654](https://github.com/handshake-org/hsd/pull/654) | ||
|
|
||
| ### Wallet changes | ||
| - WalletDB will emit `block connect` events with chainEntry and txs. Note: txs don't belong to specific wallet but walletdb. It will also emit `block disconnect` events with chainEntry. [#707](https://github.com/handshake-org/hsd/pull/707) | ||
| - Fix `signmessage` during REVEAL [#679](https://github.com/handshake-org/hsd/pull/679) | ||
|
|
||
| ### DNS | ||
| - fix negative answers & add non-existence proofs for _synth. [#673](https://github.com/handshake-org/hsd/pull/673) | ||
|
